Water Leaking Into a Car

Eddie spent 35 years in the automotive business with Honda. He is an ASE Certified Master Technician and has bruised knuckles to prove it.

If you have water leaking into your car, you need to deal with it promptly because of the many serious problems it can cause. If water sits for too long in a car's carpet, mold can grow and cause bad smells. Other problems can include corrosion of pin connectors, computer failures, sensor failures, rust, and high humidity inside the car causing your windows to fog up.

Where Is the Water Coming From?

A wet carpet is not the only sign of water leaking in a car. If you have an idea of where the water is getting into the car, check for water marks, stains, or even signs of rust. Take a close look at connectors for corrosion and check brackets for rust spots; you will be amazed what you will find when you look for it.

I have always said, "Mechanics' best tools are not found in their toolbox, they are found in their heads." Water leaks are hard to pinpoint, but once you find exactly where the water is coming in, you can access the problem spot and repair it.

Leaks From Outside the Car

There was a water leak near the back glass, the trunk and rear seat were soaked to the point of black mold growing. We had the rear glass removed professionally and found this pinhole near the urethane.

Leaking Windshield

The number one cause of a water leak in a car is the poor installation of a windshield. If you have had a windshield replaced recently, take a look at this possibility. I'm not trying to disrespect windshield replacement companies, it's just that some companies hire people who just don't care; they will cut out the old windshield and slap in the new one without proper preparation.

If a professional replaces the windshield, it will take a minimum of an hour. It takes time to remove the moldings, cut the windshield out, trim the old urethane so the new windshield sits flat, touch up any scratches in the paint from the removal process, prime the glass with a primer, and install a nice bead of new urethane.

If your "professional" replaced the glass in just 15 minutes, his or her work might be not just the cause of a water leak but a safety issue. In the event of a car crash, you could be thrown through an improperly installed windshield and severely injured. I am good friends with a guy who owns his own windshield repair company, and I see and hear the horror stories, so I write to you from experience.

Leaking Body Seams

Body seams are the second major cause of water leaking in your car. Seams that weren't properly sealed at the factory, or seams that were broken open by a car accident, will usually cause the mystery water leak. Finding the point of entry is worth the struggle.

Once you find the seam that is leaking, I recommend using 3M Brushable Seam Sealer on the problem area. This is the same sealer auto makers use in the factory to seal all seams in the body of the vehicle after they are welded. One reason I like to use this seam sealer is that it skims over in about 30 minutes, so you don't have to wait a long time between water tests. Nevertheless, if you can let the car sit overnight after sealing it, the sealer will adhere to the body seams completely, and you won't have a seam open again because of the body flexing before the sealer is completely dry.

Water-Testing Your Car for Leaks From the Outside

Finding the point of entry is the first step in keeping rainwater out of your car. This investigation is time-consuming, but something you can do yourself. You need to physically see where the water is coming into the car, not just where it is traveling along a panel or a seam. To test your car, pour water on it: start at a low point and work your way up to the roof. If you determine that water is leaking into the bottom of the windshield, there is no need to go any higher with the water test until after you've fixed this first low leak.

Leaks Into the Trunk

A foul, moldy smell in the trunk may result from water getting in around the taillights or the trunk lid. If you can identify these leaks you can get them fixed.

Leaking Aftermarket Accessories

Poorly installed aftermarket accessories are another major cause of water leaking in your car. Anything from a sunroof to a roof rack system, if not installed properly with the right sealer, will cause a water leak in a car.

If you have a factory-installed sunroof, check the drains. Sunroofs leak! That's why a factory-installed sunroof has a built-in tray with four drains, one in each corner of the sunroof. Sometimes these drain tubes become disconnected or clogged and will cause water to leak into the car. Locating the drains and checking them for proper drainage can take some time because they are usually buried in fenders and body panels, but it's time well spent. A shortcut to locating the drains is to fill the sunroof tray with water and watch where it goes when it drains. It will usually spill out in the front and the rear of the rocker panels.

Leaks From Inside the Car

Some leaks into the passenger compartment happen when it hasn't even been raining; they involve fluids created by the car's cooling or heating systems.

Clogged Air Conditioner Drain

When air conditioners take humidity out of the air in the passenger compartment, they end up collecting a lot of water that has to drain out of the car. Water dripping out of the air conditioner drain onto the ground is totally normal; water dripping onto the floor of the car from the air conditioner is not. If you haven't had any rain, and you have water leaking onto the passenger's floor, check your air conditioner drain or evaporator drain; it may be clogged or disconnected. Debris gets sucked into the evaporator from outside and occasionally will clog the drain tube. A temporary quick fix for this problem is blowing compressed air into the drain tube located under the car, but eventually you will have to remove the evaporator and clean out the debris.

Leaking Heater Core

Another possible cause of wet carpet, especially in the front of the car, when it hasn't been raining, is a leak from the heater core. Car heaters circulate coolant through the dashboard area to heat the car, and if the heater core springs a leak, coolant can drip onto the floor.

Questions & Answers

Question: I have water on the passenger floor of my 2011 Hyundai Sonata. Could this be a clogged drain in the sunroof?

Answer: More likely the drain on the evaporator is either clogged or knocked off. If that looks ok it could be a sunroof drain or a windshield gasket. Have you had your windshield replaced recently?

Question: Water leaks into my car from under the glove box. How do I fix this problem?

Answer: Water is leaking in from under your glove box because you either have an evaporator drain that is clogged, or you have some other leak. You'll need to find the point of entry by either water testing your vehicle, or try unclogging the evaporator drain by using a coat hanger or compressed air up the drain tube.

Question: I have a 2016 Ford Fiesta. I just got it brand new a year ago. This morning, I found the floor on the passenger side (behind the driver) soaked in around 5-7mm of water. I’m sure it didn’t rain yesterday but it rained hard two days before. The other side of the passenger, seats and the driver floor is dry. What could be causing this?

Answer: I recommend bringing it back to Ford; I think it may still be under warranty. There are a lot of things that can cause this, leaking body seams, missing door seals, tail light seals, sunroof drains, etc. I recommend checking the trunk for any signs of water as well.

Question: 99 Civic EX, leaks inside right rear side, where should I start?

Answer: Check the trunk first and see if there is any water anywhere in the trunk, even behind the wall panels. If the is water back there, check the rear sunroof drains and taillight gaskets.

Question: I have a leak in spare tire area in a 2008 Honda Fit. How do I fix it?

Answer: Check out this video, I found several leaks in the seam sealer near the roof run channels https://youtu.be/5bGCaQlBJRc

Question: I can hear steady dripping overhead on the driver's side of my 2009 Lincoln MKX, but there is no water inside the vehicle. Where should I begin my search?

Answer: I recommend checking the sunroof first, find out if the drains are clogged.

Question: My trunk is soaked and there is condensation on the trunk lid. Today I noticed the back passenger seat is damp and the rug on that side as well. There doesn't appear to be a problem with the stripping around any part of the car and we also washed the car and nothing leaked. Any ideas?

Answer: It's possible the leak is from inside the trunk, have you checked the complete trunk area for standing water link in the spare tire well and under the trunk liner? Taillight lens gaskets are a very common place for water to enter the trunk, also if you have a sunroof, the rear drains usually exit the vehicle in the rear quarter panels behind the trunk wall liners.

Question: There is a visible waterfall from under glove box when turned left; continued to run at every turn as if sloshing out of some sort of tray or bucket? I turned floor vent on high (not a/c) and blower motor quit after 3 minutes, won't come back on in any mode?

Answer: Sounds like your AC evaporator is full of water because it's not draining. I recommend having someone blow some compressed air up the drain tube from under the car or use a coat hanger to fish out the debris clogging the drain.

Question: I have a Suzuki Wagon R. Near the front left door, close to the door, water comes in drops under the dashboard. What is the main issue?

Answer: Look under the dash with a flashlight and see if the water is coming in from up high like next to your windshield or low like where the carpet meets the kick panel. If you have a sunroof, I'd definitely check there.

Question: My 2007 Lincoln Towncar has twice had a pool of water in the back seat passenger side well. It appeared even though we had no rain two days before. The first time there had been showers, but not the day it was observed. Where could it be coming from?

Answer: I recommend checking the AC drain in the front passengers' side foot area. If the drain is clogged, water will leak under the carpet and find its way into the back seat floor area.

Question: How can water get in a nonmoving car?

Answer: Water can enter a vehicle in many areas like the windshield seal, back glass seal, door seals, body seams, tail light lens gaskets, etc... Pinpointing the point of entry is the most difficult part of diagnosing a water leak.

Question: There is water in the back passenger floorboard when it rains. I have checked the seals on front and back doors. I also made sure that the windows were up all the way, and checked the trunk, but no luck. I’m stumped?

Answer: Have you checked the front passenger carpet? When it's raining, people use there defog mode on the windshield. This uses the AC to remove moisture from inside the passenger compartment. If the AC drain (located on the front passenger floor near the firewall) is clogged, it will leak onto the front floor and flow into the back. So check the front carpet as well, and let me know what you find, thanks.

Question: The driver and passenger floor of my 2006 Grand Caravan is very wet. Where should I look for the source, and what would be the solution?

Answer: I would first look for the cause. Is it coming in from the rain or is the problem coming from the AC not draining? Has the windshield been replaced recently? Has the vehicle been in any major accidents?

Question: I have a 2001 Toyota RAV4. The driver side floor is soaking wet after the rain. How do I find and fix this issue?

Answer: I recommend pulling back the carpet and water testing it to see where the water is entering the vehicle. Water leaks will usually leave a trail or debris or rust so you can look for signs of this before you even water test.

Question: I have water leaking into the driver's side floor well of my 1990 Honda Civic EF hatch. It's not going into the back of the car at all or the passenger side footwell just the driver's side. What could it be? I know the window regulator is bad and won't roll up all the way unless I push it up, and this only happens when it rains. But, a puddle still collects even when I haven't driven the car. Where could the leak be coming from?

Answer: It's a good possibility that your windshield is leaking on that side of the vehicle and is leaking in from behind the dash. You'll need to pull back the carpet and inspect the floor for any trails of water leaking from above.

Question: There is water in my 2014 Ford Fusion driver and passenger floorboard and we know it's not the heater core. Could our AC drain be clogged?

Answer: Absolutely, I recommend checking the drain first. Try using a piece of wire like a coat hanger to clear the drain on your vehicle.

Question: After I spray water on my windshield or after I carwash it there's no leak inside my dashboard, but when I drive it and take a sharp turn some water leaks under my dash on the passenger side floor like there's a container overflowing. How can I find out from where the water is leaking?

Answer: It sounds to me like your air conditioner evaporator is not draining and is leaking water onto your passenger side floor. I recommend finding the AC evaporator drain and clearing it with a coat hanger or a piece of flexible wire.

Question: I have a 2010 Nissan Altima, and on my driver's side when it rains, it's always wet. I also hear water dripping in the back but can't seem to figure out where it is coming from. When I drive, I hear water from the back shifting, but I can't find where it is gathered. Where could the leak be?

Answer: I recommend checking the tail light gaskets, its a very common place to have a water leak. Check your trunk for water too, if the trunk is wet, the water may be creeping into the back seat as well under the carpet.

Question: I just swept the rubber mats in my 2011 Nissan Rogue and discovered they were wet as is the carpeting under the mat on the driver's side. Do you have any thoughts?

Answer: If you have been using the AC system, make sure the evaporator is draining under the vehicle when it's running. If you don't see any water draining, it's possible your AC drain is clogged. If you have a sunroof, make sure those drains are working as well by pouring water into the sunroof tray and watching it drain from all four corners near the wheels.

Question: Water is sitting in my car under the spare tire and on the back carpet. How do I fix this problem?

Answer: Have someone get in the trunk with a flashlight, water test the outside of the car and have the person in the trunk look for the leak.

Question: I have a 2012 Chrysler 200. I have noticed after car washes and rain my driver's side rest and front get flooded with 2" of water. What is it?

Answer: There is an obvious leak somewhere. You'll need to pinpoint the entry of the water. Have you ever been in an accident or had the windshield replaced? If so, this can certainly be the case.

Question: I discovered a large pool of water on the carpet floor in the front passenger and back seat on the same side. The other side is dry, and so is the floor on the driver side. I have followed your advice and poured water on the windshield while someone else was looking with a torch. Nothing. The carpet under the glove compartment is dry, and so is the trunk. A neighbor checked my water reservoir and no leak from there. Can you help, please?

Answer: Check the drain tube coming out of the bottom of the AC evaporator; it is usually located on the passenger's side of the vehicle where the passenger would rest their feet near the engine firewall.

Question: My daughter has a 2008 Nissan rogue and has had it for ten months, just recently it has water in the driver's floorboard and the back passenger floorboard behind the driver's seat, how do I find out where the water is coming from?

Answer: You'll need to pull the carpet back and dry under it. Check the trunk for any water in the spare tire well or anywhere else in the trunk. If the trunk is dry, check under the dash with a flashlight for any trails of water leaking down against the firewall, also look for rust stains or areas of the carpet higher than the floor that is wet, if there is, water test it in that area.

Question: I have a Ford Fiesta and I found that the back seat on the driver's side is wet. Why could this be?

Answer: First, check if there is water in the trunk. It could be an issue with the headliner, or maybe snow got onto your seat?

Question: My car leaks water from where you pull the handle to open the hood of the car what can it be ?

Answer: The most common leak would be the windshield gasket, but depending on the vehicle it could be something else.

Question: My daughter has a 2010 Ford Escape, and both front floorboards get wet now when it rains. This problem just started within the last couple of months. I don’t see any sign of water on the headliner and the windshield hasn’t been replaced. Do you have any ideas?

Answer: If you have been using the AC system, make sure the evaporator is draining under the vehicle when it's running. If you don't see any water draining, it's possible your AC drain is clogged. If you have a sunroof, make sure those drains are working as well by pouring water into the sunroof tray and watching it drain from all four corners near the wheels.

Question: I have a leak at my pillars, by the windshield. It happens more so on the passenger side and my floorboard on the passenger side is wet. What could be causing this?

Answer: If you have a sunroof the front drains may be clogged. If you don't have a sunroof, it's a good possibility the windshield gasket is leaking.

Question: My truck is leaking from the frame about 2/3 the way up the windshield on both sides. What could be causing this?

Answer: Most likely you'll need to have your windshield removed and resealed or replaced, the gasket must be compromised.

Question: I have water leaking in what looks like under the center engine compartment where the shifter is located in my 2006 Saturn Vue, 2.2. Is this possible?

Answer: Yes, anything is possible. If the leak smells sweet it may be a heater core leaking, or it's possible you have a water leak, maybe the evaporator drain is clogged, and water is starting to back up out of the floor vents? I recommend checking the evaporator drain first if the fluid leak is not a sweet smell.

Question: How can I find where the water is coming in my car? A pool of water forms on the carpet in front and back well of my Nissan Micra. We have checked all the places mentioned.

Answer: You'll need to pull back the carpet where the water is pooling, dry the floor with a towel, then water test the vehicle with a hose on the roof in the area the water is seen. You'll need to have a flashlight and watch to see where the water is streaming in.

Before you start, inspect the interior of the vehicle by running your hand on the areas of carpet that go up the sides of the vehicle to see if you feel any wet carpet that isn't at floor level. If you come across an area that is wet higher then floor level, start by water testing in that area.

Question: I have water on the driver's side of my car inside the door panel. What do I need to do to get rid of the water and how do I prevent more water from collecting in the future?

Answer: Your doors have drains in the bottom along the seam, locate the drains and clean them out so the water will drain properly. Doors are not sealed and it is normal for water to drain from them, but not puddle in them.

Question: I have a 2015 Chevy Traverse. I've had no accidents and have never replaced the windshield. There is no sun roof. It drips water when raining in the front middle towards window and by the control panel. Any ideas?

Answer: Most likely the windshield gasket is defective. Sometimes there can be a weak spot and it shows up over time from the body flexing.

Question: I have a 2006 Infiniti G35, and while driving, I felt small drops of water hitting my feet as I drove. I pulled over to find that there was water coming from the undercarriage inside of my car. What do you think that could? I always feel like a female that I have subjected to foolishness when it comes to getting my car worked on, and would at least like an idea when I walk in so that I am somewhat prepared when they assess the vehicle.

Answer: Your AC drain may be clogged causing water to pool up inside the HVAC system and drip or spray out onto your feet when the interior fan is on. If it is humid where you live and this sounds like a possibility, have the AC evaporator drain checked first.

Question: I have a Mercedes A Class 63 reg. (no sunroof) and water leaks inside and onto the carpet on the passenger side; the back is soaking wet. I took it to the garage, and they said it might be a blocked AC drain as the pollen filter was absolutely soaked. They cleared the debris, and then they did a water test, and the problem was sorted. A few weeks later the problem is back! Is it really blocked drains or something more serious?

Answer: Yes, it could be a blocked drain. Since the mechanic only temporarily cleared the drain, it's like pushing the hair back down the tub drain without removing it from the tub; it will flow back down the drain and will clog it again. You could keep clearing it with a coat hanger or have the evaporator removed and have it completely cleaned of debris, but that costs a few bucks. They will need to discharge the AC system and remove the evaporator box from behind the dash.

Question: I have a 2010 Cobalt and every time it rains, water gets in on the driver side right above where the diagnostic plug is and over the footrest next to the brake. What could be leaking?

Answer: Most likely the windshield or a body seam in the bulkhead area where you wipers rest.

Question: I have isolated the front driver side sunroof drain hose as the problem. I pour water in and some make it to the ground behind the tire, but it seems as though more ends up in the headliner at the corner of the windshield. Occasionally some will leak out of panel by the door near the gas release level. How do I fix this?

Answer: You'll need to lower the headliner in that corner and try to repair the leak, it will be tight and you may bend the headliner but you need to stop the leak asap.

Question: I have a 2014 Nissan Versa. Because of the cold/ice weather we have had, I noticed right above the driver's door that the ceiling was wet. Now if it rains heavy it continues to be wet. What can I do to fix it?

Answer: Call your local windshield repair shop and have them check the windshield gasket for a leak.

Question: Would a wet fuse box cause my car to not crank?

Answer: It depends on what got wet. If a relay shorted internally because of water, then yes. If the outer part of the fusebox got wet and nothing internally did, then most likely that is not your issue.

Question: Rain water leaks into my car from the sunroof. Where can I take it to for repairs?

Answer: I recommend you take it to your local automotive glass repair company, someone who replaces windshields may be able to help.

Question: My daughter broke off the top antenna of her car, and it got rained on. No water got in the passenger area of the car. She eventually had the antenna fixed, but how do we know if there's been damage and what should be done?

Answer: If water never entered the vehicle there should be no need to worry, outside antennas are made for the weather, even if they are broken.

Question: Every time it rains my floor gets wet on the driver's side. My husband broke the hood latch on my car and it hasn't been replaced. Also, my windshield got hail damaged during the storms in 2017, and I got my windshield replaced. My sunroof had a recall and work was done on it all in the same year. The glass company said the drain plug is clogged on the driver's side coming from the sunroof. What do you think could be the problem?

Answer: There are a lot of possibilities because you have had so many repairs that could cause a water leak, check out this video on how to check your sunroof drains. https://youtu.be/663jF7O-jkA

Question: Our daughter's car started having water coming up from her front passenger floorboard. This is the first time this has happened. Do you know why?

Answer: Water usually flows down; I recommend checking the carpet up on the sides and up under the dash. A common leak is the Air Conditioner evaporator drain tube being disconnected or clogged; I recommend starting with checking the drain tube.

Question: I have water inside of the trunk liner whenever I wash my car. Where could that possibly be coming from?

Answer: If the water is on top of the trunk mat, then it is possible your back glass seal is leaking, or the trunk lid gasket is leaking. If the water is under the mat, it could be coming in from the taillight gaskets or a seam in the body. There are so many reasons for why water is entering a vehicle, so it's best to soak up the water with a towel and water test it with a dry trunk to see if the water is leaving a trail, then just follow the trail to the point of entry.

Question: Why is it that when I go through the car wash, my passenger window on my 2006 g35 Infiniti leaks?

Answer: You probably need a window run channel.

Question: I recently had cross bars installed that attach to the running bars on my Jeep Renegade. When I open my passenger side window after there's been rain, water leaks down into the car. Is that normal?

Answer: Yes, it is possible to have water dripping from the crossbars into a window. It might be worth investing in some window visors to help divert the water.

Question: I have a water leak in my trunk mainly from splits in the seam sealer. Can I apply new sealer to the old or do I have to fully remove, and do I need some type of primer before and/or after applying? Is wax/grease remover necessary when applying the sealer as well?

Answer: You can apply new sealer over the old seam sealer, I recommend cleaning it up with some rubbing alcohol or lacquer thinner just so it adheres better.

Question: What is the most common leak on a 2003 Honda Civic LX two-door?

Answer: An oil leaking from the valve cover gasket is most common.

Hi Joshua,

Does your car have a sunroof? If so the sunroof tray may be filling up with water and leaking from the front and rear of the tray. I recommend you check the tray and make sure it is draining properly "see my video". The electrical problem will need an expert, someone who can test the battery for a draw and at the same time removes the fuses one by one to pinpoint the issue. Let me know if the sunroof tray is draining, thanks.

Eddie Carrara (author) from New Hampshire on July 13, 2020:

Hi V,

It's normal for water to enter the door, your problem is it's not draining. Go to the 15 min mark on this other video I made and it will explain the drain in the doors. Let me know if this helps, thanks. https://youtu.be/veFEvlXnGlE

Eddie Carrara (author) from New Hampshire on July 13, 2020:

Hi Sam,

I hope this is the least of your worries, any car that leeks for long periods of time usually have a lot of electrical issues. I recommend you wet vac as much water as possible from under the carpet and out of the carpet, then park the car in the sun, turn on the heat full blast, turn on the recirculate button and make sure the AC is working and have that on at the same time you have the heat on. Doing this will suck the moisture out of the car completely and you will be able to tell when it's dry when the water stops dripping from the AC evaporator under the car. The car will have to idle sometimes up to 24 hours to completely dry the interior. Better fill your gas tank lol. Let me know how you make out, thanks.

Joshua on July 13, 2020:

Hi Eddie, I have a 2008 Volkswagen passat and there are 3 things i would like to get some help on, the first one is:

water is seen around the two back seat floor of my car, especially when it rains and if I drain it, I can still feel water dripping down from the trunk of my car but there's no evidence of any water in my trunk.

Secondly, when it's raining, water will be dripping down from the upper part of my windshield.

Thirdly, my battery died off if I refuse to remove the batter head after switching off my ignition and I have removed both the light in my compartment and the one on my trunk, still the battery still dies off if I don't remove the terminals, please any suggestions on these 3 problems?

V Daniel on July 12, 2020:

I was driving and heard water splashing in my passenger side door, when I open it water stared to leak out. How and where could the water be getting in

Sam on July 11, 2020:

Just bought a eos Volkswagen.. the sunroof had problems so previous owner tarped it up eventual lol.. so the cars like a swimming pool.. how do we dry out the totally soden fire wall ?

Eddie Carrara (author) from New Hampshire on June 27, 2020:

Hi Philip,

It's very likely! Usually, the floor in a vehicle is lower in the rear than the front and water usually run downhill so I suggest you pull back the carpet in the driver's side front floor and inspect it, most likely it's just as wet as the back seat but it's just not pooling. Let me know what you find, and if you have more questions, you know where to find me :)

Philip on June 27, 2020:

Thanks for the article!

I have a 2007 Kia Rio that recently began pooling water under the driver seat when it rains. One thing about my car is that the rubber seam on the windshield on the driver's side tends to fly out when I drive on the highway. About a month ago, I taped it down using some electrical tape. Not long after that is when I began noticing the water pooling in the car.

Is it possible that the windshield seam is causing a leak that travels all the way to the *back* of the car? The area in front of the driver seat has remained relatively dry, with only hints of moisture but no pooling. How likely is it that the windshield and back floor pooling are related?



Eddie Carrara (author) from New Hampshire on June 22, 2020:

Hi Allen,

It sounds to me like the trunk is where you should start looking for trails of water (see video) the water will usually rush forward when braking so that probably why there is water in the rear driver's side floor area.

Allen on June 20, 2020:

Great blog.

Q: i have a 2004 camry, leaking left in the trunk and wet under the rear driver side seat. I checked everywhere but in vain.

Any answers? Thanks.

Eddie Carrara (author) from New Hampshire on June 11, 2020:

Hi Nancy,

Which floor, driver's or passengers? Are you using the AC? Are the back carpets wet? Let me know, thanks.

Nancy on June 09, 2020:

I just noticed my carpet in the front floor is soaking wet

Eddie Carrara (author) from New Hampshire on May 18, 2020:

Hi Rob,

You're welcome, and wow, you've done your homework lol. Yes, body seams are very difficult to find and most shops will not dig that deep, they just give up. I don't know of any drains under the cowl, usually, they are just channels to direct the water out from under the windshield. I also recommend you use a garden hose to check the water leak. Start water testing low on the body and slowly move your way up the body 6'' in 5-minute increments until you get to the top of the windshield, this will help identify the approximate location of the leak, it's time-consuming but worth every minute. I have had to take quite a few fenders off to find the source of the leak, once the fender is off you still need to dig through welded boxes mounted to the firewall and frame and it's not an easy task. Sometimes we will use a hole saw to open up parts of the welded boxes to peek inside and add brushable seam sealer to any exposed seam. If you know the general area of where the water is entering I recommend you wash the area extremely well, let it dry, then use either rubbing alcohol or brake cleaner to remove any remaining oil, grease, or grime, then apply 3M brushable seam sealer to all visible seams in the area or any questionable spots, let it dry and then water test with a garden hose again to verify the leak is fixed before you put the car back together. Let me know if this helps Rob, and keep me post on your progress. You have inspired me to make another video explaining the process :)

Thank you for the insight to figuring out water leaking problems. I think I may have a really hard one for even you to figure out. I am not saying that you are not able to, I am saying this seems to be a problem that no one can figure out on the internet.

I have a 2014 Ford E-350 Super Duty Cargo van. Like many other people on the internet I have worked hard on trying to find where the water is coming from and getting to my . Short of pulling fenders, I am at a loss as to what to do.

Here is what I know:

• The truck only has 35,000 miles on it and is looking brand new. I have some very small water marks on the metal behind the driver side kick plate close to the fire wall. The water is coming from the seam behind the kick plate about 6” from the floor.

• The water is getting the padding under the rubber front mat wet.

• Water is collecting where the floor starts to rise leading to the fire wall.

• Some water makes its way into the door sill under the door plastic foot plate/trim.

• A little water is collecting under the gasket of the engine cover at the floor.

• All the above references to the leaking is from the kick plate and on the driver’s side.

• On the passenger side the water to appears to be coming from near the engine cover compartment on the firewall by the dash. No water is coming in at the kick plate.

• The windshield is original with the factory Ford sticker still attached to the glass.

• Someone has already used a Polyurethane caulk at many of the seams under the rubber mat. Some one thought the water was when the truck was driven which is not when it leaks. The leaking is when it rains. All of the rubber seal is intact and in excellent condition.

I have removed the wipers cowl and looked down into the cowl to find the drains. I am not sure where they are for sure, but if the drains are where I think they are, I was barely able to get my hand into the hole to clean them out which I did. I still have leaking.

Looking on the Internet someone said that there are hoses that lead down from those drains, but I supposedly won’t be able to get to them even if I take the fender off.

I am going to pull the dash apart again to install a new sub-woofer and amp today. And while I do that, I am going to pour water from the roof down the windshield to see if I can make it leak and where the water is coming from. After the roof and the window pillars, I will pour the water in the cowl directly. Hopefully, I will see the water come in, but that still will not tell me what I need to stop the water from coming into the truck cabin, or inside the fenders.

I will look at anything that comes through the firewall that might be leaking and caulk that up or replace the grommets. Please give me any insight in what you know regarding water leaking under the dash.

Lastly, It’s not the heater core.

Thank you,

Hi KerriAnn,

The roof must have some channels where you would attach accessories like a roof rack. Inside the channel maybe where your leak originates from because of so seam sealer that has failed or something. I would start by looking at the channels closely, you may need to remove some trim or covers to expose the channels but that is the least of your problems. I also recommend you check the back seat floor under the carpet, I'm sure it's getting wet. Let me know, thanks.

KerriAnn978 on April 27, 2020:

My 2015 traverse roof has been leaking above my rear drivers door not dripping but enough to soak the headliner, the spot has now got so big it extends over my drivers door. I do not have a sun roof and havent been in any major accidents. None of my floors are wet. The spot orginally was only over the rear door for about 9 months or so, but with the recent new england weather has got worse in the last 3 weeks with the recent rain. Any advice? Thanks!

Eddie Carrara (author) from New Hampshire on April 16, 2020:

Hi Beth,

The drains are hidden behind the interior panels. The front drains will be located behind the side panes near your feet like where the hood release is located, they are usually between the sheet metal and the rear ones are usually located behind the panels in the cargo area, you'll need to do some disassembling of the interior to find them. If you haven't watched my video at the bottom of the article "How to Find Water Leaks in a Car" I recommend you watch it, it's a bit lengthy but informative. Let me know if this helps.

Beth on April 15, 2020:

How can I access bottom of sunroof drain tube on a 2014 Nissan Pathfinder?

Eddie Carrara (author) from New Hampshire on April 15, 2020:

Hi Ruben,

If you watch the video above titled "How to Find Water Leaks in a Car" it will explain the process, once you find it then we can explore the options on how to fix it. Let me know if this helps, thanks.

Ruben on April 15, 2020:

My dad has a 2006 chrysler 300, its leaking water on driver side and back floor. Is there a drain clogged? And if so where would the drain be because we cant find it.And how do we fix it. Please help.

Eddie Carrara (author) from New Hampshire on April 10, 2020:

Hi Alonzo,

Does your car have a sunroof? Has the windshield been replaced recently? Does your windshield fog up quickly when you start your car? When do you see water on the front floor, after a rain or all the time? Is the carpet wet behind the driver's seat? Is there water in the trunk or spare tire well? Let me know, thanks.

Alonzo on April 10, 2020:

I have a 2005 Buick lesabre and I have a leak on my driver's side on the carpet I wanted to know what it could be leaking from

Eddie Carrara (author) from New Hampshire on March 28, 2020:

Hi Summer,

Thank you for the feedback, I really appreciate it :)

It sounds like you have more than one problem here. Your car alarm may be activated because of your accident, there is a hood switch that may be damaged and causing a false alarm, your local Acura dealer can test this or you may want to just unplug it to test my hypothesis.

The front floor getting wet is most likely a problem like a windshield or a sunroof drain, it could also be a body seam but let's go with the easy checks first.

The back seat getting wet is water flowing from the rear, I bet if you check the trunk area under the carpet and in your spare tire well you'll find pooling water, it's a quick easy check. If you find water in your trunk you'll need to look for the point of entry by looking for trails of water like I show in the videos.

The center console will normally get quite hot because the catalytic converter runs down the center of the car and is usually located somewhat below the center console area. I think maybe the AC isn't working as good as it used to an that may be the underlying issue.

Let me know if this helps, and if you need more questions answered or you want to inspire me to create more great content, you know where to find me lol :) I'm happy my content helped answer some of your questions :)

Summer Greene on March 27, 2020:

Sweetheart ! I loved the article. I’ll begin my quest to find the leak in the morning. BUT I am SO pleased to see that you’ve worked with Honda, I just had to ask you about my Acura.

It’s an 06 TL, and when I went to vacuum out my car, I seen the backseat on the driver’s side was soaked ! So was the driver’s side floor, but that had been so for a little while now. I did have a car accident last April but the driver’s side floor had been leaking a little before that, and the accident was very minor, extremely minor. I rear ended someone. But I think maybe at this time, I’ll say it’s getting worse. Now I do not know if this is related, but my middle console is overheating, can’t really keep my AC cold enough & years ago when it use to rain my car alarm would go off and I would have to leave my doors unlocked, with the driver’s seat belt engaged. Your ideas & suggestions are greatly appreciated. Thank you so much ♥️

Eddie Carrara (author) from New Hampshire on March 22, 2020:

Hi James,

If you have a sunroof I recommend you check the drain tube on that side, it's possible a rodent has chewed it and it's leaking or maybe the windshield is leaking. Has the windshield ever been replaced?

James Walker on March 22, 2020:

I have a 2010 Mazda 6. After rain water leaks into interior fusebox(driver's side).

Any suggestions?

Eddie Carrara (author) from New Hampshire on March 15, 2020:

Hi Tee,

If you have water on all four corners of the floor and the car wasn't driven I suspect the windshield is the problem but it will need to be water tested to verify. It is very unusual to have water completely covering the floor without the car moving. Has the windshield ever been replaced? Has the car ever been in a serious accident with extensive body damage? Let me know thanks.

Tee Davis on March 14, 2020:

Yesterday was sunny, my floors were dry. It rain all last night and is currently. My car has been parked all evening until this morning and my driver (front) and passenger (front and back) floors are soaked. This only occurs when it's raining. It does not occur when i use my heater. I been dealing with this for 2 years now. I originally thought it was the kicked up rain water from driving because my car is normally in a carport but last night it wasn't so im confused. I had my condenser/radiator replaced last week (was driving w/o ac for 4 years)

Eddie Carrara (author) from New Hampshire on March 04, 2020:

Hi Ritesh,

Look in the trunk to see if it is wet if so you'll have to start removing some of the back panels and look for trails of water. If the trunk is not wet, feel under the front carpet for any moisture. Let me know what you find, thanks.

Ritesh on March 02, 2020:

I've a nissan ssentra SV, recently noticed a lot water there in the floor of the back side of the car. Trying to understand from where we have 2'' water logged. not sure from where water is coming from

Eddie Carrara (author) from New Hampshire on February 11, 2020:


Thanks, I have a new water leak diagnosis video coming out soon and I'll post it here and on YouTube.

With your leak I recommend you pull the seal off around the top of the door jam and take a look at the top of the headliner, be careful, there may be water pooling up there, some headliners have a fiberglass type backing which is water-resistant. It's possible a mouse chewed the hose or it developed a leak because of age. Let me know if you find anything, if not, we can dig a little deeper.

Eddie Carrara (author) from New Hampshire on February 11, 2020:

Hi Jason,

Look in the rear of the vehicle for any water in the cargo area under the carpet and plastic panels. Has the car ever been in an accident? Let me know what you find, thanks.

jdknetflix on February 11, 2020:

Eddie, I really enjoy how clear and practical your advice is on this forum. Thanks very much.

I drive a 2001 Honda Accord, with a factory-installed sunroof. I dismissed damp carpet for weeks but this morning there was a pool of water on the front passenger-side floor (it rained during the night). I found where it's dripping from: the edge of the roof where it meets the door. More specifically, it's wet in the area around the handle, right around the midpoint of the door. The areas surrounding the sunroof are dry.

I don't see any cracks or holes in the rubber seals around the door and I don't think anyone has hit my car recently. Can you advise me on what i should do next? Thanks!

Jason on February 09, 2020:

Hello Sir.

My 2008 Honda CRV has water getting on the passenger side back seat carpet only. Just in far back right corner. I checked the water flow of the Sunroof on all four sides and they drain just fine.

I'm so lost lol

Eddie Carrara (author) from New Hampshire on January 07, 2020:

Hi Maranda,

Water will always flow towards the back seat because it sits lower than any other part of the car. I recommend you check the front carpet under the floor mats and the trunk in the spare tire well and surrounding area for any water or wetness, this will indicate where the water is coming from, that would be the first step and will prevent you searching in all different direction. Let me know what you find and I can help guide you to the next step.

Maranda3377 on January 07, 2020:

Hi, I have been struggling with a bad water leak in my car for a while it creates a huge puddle in the rear passenger floorboard and I feel like it does happen when it rains but I’m really not sure, I do have a sunroof. it’s a 2008 Chevrolet Malibu and no mechanic can seem to figure it out which I don’t understand. I am going to start running tests on it like the sunroof test but I was just wondering if you had an exact direction on what I should look for since mine is in the backseat floorboard..

Eddie Carrara (author) from New Hampshire on December 17, 2019:

Hi Joeanne,

You'll need to at least find the path or direction where the water is coming from, is it coming from the rocker panel, trunk area, roof? That would be the first step, it could be clogged rocker panel drains and the water is backing up or it could be from the rear glass gasket traveling behind the rear seat and draining onto the back floor, the possibilities are endless so you need to find the water path. Let me know if this helps.

Joeanne on December 13, 2019:

Hi my car is leaking behind the drivers door its a 57 clio it has rained non stop for four days any idea thanks

Eddie Carrara (author) from New Hampshire on November 21, 2019:

Hi SpecOfSand,

If I were you I would call the manufacturer and ask them for a buyback deal because of the issues with the smell, rust, and possible electrical issues in the future. They may offer you some kind of deal on a new vehicle or something. If they don't want to help, I recommend you ask to have this problem documented at the dealer, replace the carpet and any other components that were damaged from the water intrusion.

SpecOfSand on November 20, 2019:

Hi, Wife has an 11 mth old Fiesta Vignale (from new). She first noticed bad condensation & cats pee smell over the past mth, checked the car to find a LOT of water in the boot, pretty deep in places.

Rear passenger floor soaking wet as well. Took car back to dealer who have had it for 6 days but no word from them yet.

When they tell us we can have it back what should we be looking for, checking, should we ask someone to check it over first?

Our neighbour told us the ECU unit could cause problems, also rust, smells & ruined carpets that will deteriorate faster than normal.

Will appreciate any advise offered, thanks.

Eddie Carrara (author) from New Hampshire on November 02, 2019:

Hi Cameron,

The good news is it's a 2018 and it should be under warranty. I recommend you call Toyota customer service and report the problem so you'll have a case #, it's like an insurance policy for any problems that may arise in the future. You can vacuum up the water with a wet vac (don't forget to remove the vacuum filter when using it for water) for now but I recommend you be adamant about them replacing the carpet under warranty so you don't develop a mold problem in the future because more then likely they will not dry the carpet properly. Keep me posted on what happens and if you have any other questions before you bring it in I'll be right here :)

Cameron on October 31, 2019:

Hello, I have a 2018 Toyota Corolla. Have had a funky smell the past week and just thought one of the kids had spilled a water bottle or something. Last night I did a closer inspection and realized all the carpets in the car were soaking wet. It doesn't seem like one area is more wet than another. I pulled the passenger side dash apart to check for any glaring leaks but didn't find anything. Car does not have a sunroof and it doesn't appear water is coming in from the trunk area. Set up an appointment with the dealership for next week so a professional can try and find the source of the leak. In the meantime, is there anything I can do to prevent the risk of mold or mildew? Thankfully it is fall so temperatures haven't been crazy hot. Also, should I be concerned about electronic components being compromised from this event? I have no choice but to drive the car until I can take it to get looked at next week.

Eddie Carrara (author) from New Hampshire on October 29, 2019:

Hi Mikaela,

I recommend you check the back of the vehicle near the tail lights to be sure the water isn't entering back there. I also recommend you check the front carpet under the floor mats to be sure water it's coming in from the front. Watch the video in the article on how to test the drains in the sunroof tray so you can verify they are draining properly. Let me know what you find, thanks.

Mikaela on October 26, 2019:

Hi, I have noticed that the carpet on the floor in the back seats of my 2012 GMC Terrain are wet. I took it to the dealership a month ago and they said my sunroof wasn’t closing all the way and fixed that, but water is still coming from some where. Any idea what it could be???

Eddie Carrara (author) from New Hampshire on October 22, 2019:

Hi Marvin,

Does the vehicle have the original windshield? Did it just start leaking? Do you have any idea where the water is trailing from?

Eddie Carrara (author) from New Hampshire on October 17, 2019:

Hi Jotika,

Check to see if the trunk or hatch area is wet as well, also check the spare tire well for water, if it's wet back there you'll need to find the leak in that area. Let me know if this helps and if you need more assistance.

Jotika on October 16, 2019:

Sorry was speaking to you b4 cant find your messages

JotikaParekh on October 16, 2019:

I have a wet carpet on the back off the drivers seat.

Eddie Carrara (author) from New Hampshire on September 09, 2019:

Hi Ciara,

I recommend you start by having someone check your AC drain, I think it may be clogged. If it hasn't rained, the water must be coming from the air conditioner. Let me know what you find.

Eddie Carrara (author) from New Hampshire on September 09, 2019:

Hi Ilene,

I would start by checking the trunk to see if it is wet or your hatch area, which ever your car has. Water will always run towards the front of the car and most likely the problem area is in the backside of the vehicle on the driver side. Let me know what you find maybe I can help pinpoint the leak, thanks.

Ilene on September 06, 2019:

Car is damped in the back of the driver side. The back is soaked but it’s just the back of my driver side. What to do? It’s a old car and I don’t want to put to much money into it.

Ciara on September 01, 2019:

My floor is wet I’m the front and back mainly on passenger side and it hasn’t rained my car is a 2007 Lexus gs350

Eddie Carrara (author) from New Hampshire on August 31, 2019:

Hi MJ,

Are you using the air conditioning system? If so, is there water dripping out under the passenger's side floor onto the ground? If not, most likely the drain for the AC evaporator is clogged and is not draining outside the vehicle but onto the passenger's floor. Let me know, thanks.

Eddie Carrara (author) from New Hampshire on August 31, 2019:

Hi Pat,

Has the windshield been replaced? Do you have a sunroof? Are any of the other floors wet like the passenger's side, back seat area, or hatch area?

I have a water leak in the front passenger side under the glove box where the front mat meets the center of the car in the floor area. I have had the sun roof checked, but there is a water drip when there has been no rain for days. (?)

Eddie Carrara (author) from New Hampshire on August 19, 2019:

Hi Gina,

Is the water on top of the front seats and on top of the back seats? Like is the water dripping from the roof?

Eddie Carrara (author) from New Hampshire on August 19, 2019:

Hi Kimmy,

Not usually, but you need to make sure this is all documented just in case you do run into something unusual on the future. The leak was found quick so most likely there is no damage from the water.

Kimmy Lewis on August 10, 2019:

I purchased a used 2019 Infiniti QX80 and noticed a water stain in the drivers side area near the dashboard. The dealership advised the sunroof had a cloggled train tube. They are going to fix the clogged drain tube in the sunroof and replace the carpet and the quarterpanel. My concern is will this cause any electrical damage long term?

Gina Myers on August 10, 2019:

I have a 2004 Pontiac Vibe and im having leaking somewhere. My backseat all the way across have white patches on them and my front seat too. Where would you think it was coming from . It just started a couple of weeks ago and wont stop.

Eddie Carrara (author) from New Hampshire on July 31, 2019:

Hi Cindy,

If you haven't watched my video on the Subaru sunroof leak, I highly recommend you start there. The AC drain is usually located on the firewall on the passengers side of the vehicle near where the passenger would rest their feet. I recommend cleaning the drain if the sunroof is not clogged. Let me know what you find.

Eddie Carrara (author) from New Hampshire on July 31, 2019:

Hi Bonnie,

It possible you may have some wire damage at the connectors, but it all depends on where the water is trailing. I recommend you check the path the water travels and inspect all eletrical connectors in that area. I you can find out where the XM receiver is located you can inspect the connector there as well.

Eddie Carrara (author) from New Hampshire on July 31, 2019:

Hi El,

I use 3M brushable seam sealer which you can buy on Amazon, be sure to clean the surface extremely well and use rubbing alcohol on the surface before applying the sealer. The rubbing alcohol will remove any oils or grease on the surface and the seam sealer will bond completely. Let me know how you make out, thanks.

Dealership is trying to tell me this is not related. What other damage, including rust, mold, has occurred?

cindy zalewski on July 26, 2019:

I have a 2012 subaru outback. Just recently had funky smell and tracked to soaked carpet under drivers seat where AC vent is. recent hot/humid days in WI. I do have a sun roof which I see is a standard question. No marks/signs of water elsewhere. I dried it out hoping a window may have been slightly open.

Wet today directly posterior to heat/cool vent. nothing else wet anywhere. Did rain last night too.

Where to start???? Help

Eddie Carrara (author) from New Hampshire on June 12, 2019:

Hi Martin,

If you don't see any water draining from the bottom of your vehicle when running the AC, most likely the drain is clogged and needs to be cleaned. Let me know what you find, thanks.

My 2009 Galant has water leaking onto rear seats, the headliner does not appear to be wet. it's also leaking on seatbelts and back of seats but not side of seats. Only happens during hard rains , not like when I go through the car wash... found wet in the trunk also this am all the way up near where back seats are. Any help would be appreciated as I am 65 and on disability so can't afford a trip to the dealer.

Karen on June 09, 2019:

I have a 2009 Mitsubishi Galant everytime it rains real heavy the back seats get wet not soaking wet but just wet I cannot feel any water coming in between headliner and the back window. Any ideas?

I have a 2015 Chevy Malibu and the drivers side front and rear floorboards are wet. There is no sunroof in this vehicle. Appears to be clear water leaking and no smell. Any idea of what may be causing this. Thank you.

Eddie Carrara (author) from New Hampshire on June 05, 2019:

Hi Payton,

Youll need to pull the carpet back and start water testing. Have you checked the sunroof drains? Make sure all drains are clear by pouring water in the sunroof tray and verifying the water is draining at each of the 4 drains.

Eddie Carrara (author) from New Hampshire on June 05, 2019:

Hi Sharon,

I recommend you start by checking the AC drain on that side of the vehicle as I explained in the article :) Let me know how you make out.

Hi Thomas,

CAn you be more specific like where you would find these and on what type of vehicle? Thanks.

Eddie Carrara (author) from New Hampshire on May 28, 2019:

Hi JJoe,

Keep in mind that most doors/trunk lids have drains on the bottom that can become clogged, so be sure they are clear of debris if they're visible. Tail light lens gaskets are very common leak areas on tailgates FYI. Let me know if you have more questions.

Eddie Carrara (author) from New Hampshire on May 28, 2019:

Hi Tim,

It sounds like your leak is coming from the trunk and flowing forward. I recommend you put a hose on the trunk and have someone sit inside with a flashlight, it's the only way to know where the water is entering. Make sure everything is out of the trunk so you can see the stream of water quickly.

Eddie Carrara (author) from New Hampshire on May 28, 2019:

Hi Makayla,

I wish I had the answer for you but the possibilities are endless. If you can find someone to help look for the leak you can follow the information I put in the article and you would most likely find the point of entry, but it may take some time and effort.

Makayla on May 27, 2019:

I have a volvo 2008 v50 hatchback

And water soaks the floor behind the drivers seat on the floor. But nothing else in the vehicle is wet, my macanique said there was a hole in the sealer around the windshield and he fixed that and he said the AC hose was fine. But there is still water coming in.

Where do u think it would be from?

Tim on May 26, 2019:

I have a 2002 Dodge Neon. When it rains, the carpet gets soaked on the passenger side in front and rear. Water in the trunk too. I replaced a bad seal on the trunk and pulled the carpet out to dry. Carpet is soaked again a month later. What should I check?

JJoe Morris on May 26, 2019:

My problem is water in the trunk lid that has accumulated after rain or washing. might be 1/2 pint or more and drains out when I lift the lid.

Thx for any ideas.

Thomas on May 24, 2019:

Find and check your firewall drains

Eddie Carrara (author) from New Hampshire on May 23, 2019:

Hi Lori,

Most likely you have something else leaking, you first need to find out where the water is entering, front or rear. Also, check the trunk area, water will usually run forward when stopping.

Lori on May 23, 2019:

I have wet carpet on both driver and passenger floorboards (both front and rear). Could this be from a sunroof leak or is there some other possibility?

Eddie Carrara (author) from New Hampshire on May 21, 2019:

Hi Danielle,

Are you sure it only happens when it rains or when you run the AC? The evaporator drain could be clogged or it's possible your sunroof drain on that side has become disconnected somehow.

Danielle on May 17, 2019:
