Water Leaking Into a Car

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.

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

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

    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.

  • 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?

    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.

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

    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?

  • 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?

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

  • 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?

    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.

      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.

      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

      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.

      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?

      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 :)

      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?

      Thanks,

      Philip

      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.

      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 :)

      Eddie,

      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,

      Rob

      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.

      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!

      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.

      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 :)

      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 ♥️

      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.

      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)

      Hi JDK,

      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, 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!

      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.

      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..

      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.

      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.

      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.

      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 :)

      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.

      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.

      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.

      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.

      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.

      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.

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?

      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.

      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.

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.

      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.

      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.

      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.
