Water Leaking Into a Car

Updated on June 10, 2018

Eddie spent 33 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

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 the Inside of 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

  • 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.

    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.

  • 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?

    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.

  • 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?

    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.

      Hi Sherry,

      That is a very unusual place to find water in an Odyssey. Your going to need to pull back the carpet and look for signs of water trailing from the front of the vehicle. I recommend checking the passengers side first because that is where the AC evaporator is located and sometime the drains can become clogged and leaking inside the vehicle. if everything looks ok on the front passengers side, check the drivers side carpet. I say to check the front because water will usually travel from front to rear in a vehicle because of the floor pitch and movement of the vehicle. Let me know what you find and if you have more questions, I'll be right here.

      Hi, I found water in my drivers side front and back of my car after a heavy rain. There was no water on the surrounding carpet, just the floor. The back had more water buildup but my car was on a slightttt decline. I took it to the dealership and they said they didn’t find a leak but I’m not convinced. I haven’t picked my car up yet, but any ideas on where the water could be coming from? Thanks!

      Hi Eddie,

      I have a Honda Odyssey 2007 and I have found out that my boot carpet is wet, I checked the spare tyre boot and I have found out that there’s is a pool of water in there. The water seems to have been there for quite a long time because mould has been growing on the tyre. There has not been any other places that have been wet and my car has never had accidents before. Can you identify what the problem is?

      Hi James, sorry for the late reply, You could use a wet vacuum to suck up the water, and there's some wires that run along the floor but are pretty well protected so don't worry about that yet.

      Hi Eddie,

      We have an Audi Q5 and it is no longer under warranty. If a windshield got tested for a leak issue and they find it was due to the seal, can one press further to Audi for assistance in replacement due to manufacture ‘error’ and/or defect?

      When I turn to the left the car starts making a funny noise through the ac if it’s on. If the ac is off, water starts leaking from under the glove compartment and onto the floor board. What do you think that is?

      Hi Justin,

      Check that evaporator drain, if it's clogged and you are using the AC, the condensation/water will find another place to drain and usually it's the seam of the evaporator onto the passenger floor.

      Hi Darcy,

      Are you using coolant in the cooling system (radiator)? If so, if the heater core was leaking you would have a sweet smell inside the car and the wet floor would feel slippery because of the antifreeze. If condensation is forming on the out side of the wind shield that means the windshield is colder then the outside temp, also keep in mind that when you use defrost the AC automatically kicks on in newer cars. Is the evaporator draining at the bottom of the vehicle when you are using the AC?

      I have a 2006 chevy Silverado, leaking water on to passenger floor, carpet is soaked. I tried cleaning out the AC drainage area with compressed air, and also used suction from a wet vac in the same drainage area. Still leaking. AC is NOT on but using circulated air from blower motor, not raining. There is condensation that forms outside the windshield but no condensation inside windshield. what else can I trouble shoot before I tear apart dash to get to heater core? Anything simpler?

      Hi Jenny,

      I recommend having the drain on your evaporator checked, it may be clogged and is filling up with water. If it's not clogged, most likely your windshield is leaking by what you have described. Have you ever had the windshield replaced?

      I have a 2004 Honda pilot. I've noticed when it rains my passenger floorboard is getting soaked. When I was driving I noticed water leaking from under the dash and when I went around a curve water pored out from the middle of dash on to driver side and on passenger side. What could this be?

      Hi Richard,

      I recommend opening your sunroof all the way and have a small bottle of water in hand. Go to the side that has the leak and pour water in the sunroof tray ( the tray is located in the sunroof track area and you can find the drains in each corner) and see if it drains properly, if the water puddles up in the corner and doesn't drain, that is your problem, but if it drains out the corner and exits the drain tube behind the front tire, the drain is working with no obstructions.

      If you think the windshield is leaking, try using a grand hose at low flow just over the windshield gasket where you notice the leak, but don't let the water near the sunroof gasket. Let me know how you make out, thanks.

      I had a windshield replaced and have a sun roof on a 2012 Honda Civic. The right side now has moisture/water on the inside passenger side of the windshield when it rains. The window repair person says it is a slow draining sun roof related. My question: Could the windshield replacement have pinched or caused the backup during heavy rain resulting in inside the windshield moisture? They say their work did not cause the problem. There has never been a leak from the sun roof until now.

      You'll have to locate the drain tube and either reconnect it or repair it, most likely it's disconnected at the rubber boot behind the kick panel.

      I have a 2009 Mercury Mariner Premier that has a wet carpet on the drivers area. I removed the kick panel under the dash on this side and then poured water into the front left drain hole at the sun roof. Water came out behind the tire on the front left as I believe it should have, but also down where the kick panel was removed. What is the probable problem and fix?

      Hi RCHuge,

      It is normal for water to be inside a door, it is not a sealed unit and there are drains at the bottom of each door so the water can exit. If water is in the speaker wires it may be from the angle the wires are at? You could try using black electrical tape to seal out any water by wrapping the wiper loom from the rubber boot to the connector, that should stop any water from getting into the loom. Let me know what you think, thanks.

      I have a 2009 Saturn Outlook and have been through the hassle of the clogged sunroof drain, emptying out on my fuse box and making my electronics go crazy. Got that fixed. Now I have water in my rear door speaker wires. If I disconnect the electrical connectors from the door, water pours out of both sides of the vehicle, wire harnesses. Even though they have rubber gaskets and seem to seal really well, water still gets in. I don't know if it's coming from the rear sunroof or if it is getting in through the window scrapers. I haven't taken the door apart and hosed it down yet. I was hoping to find someone who could give me an idea and some pointers first before I go disassembling my interior in search of leaks. Any help would be greatly appreciated. Thank you.

      Hi Forrest,

      I recommend checking the trunk area under the trunk liner and spare tire well, the most common areas that leak are around the tail light lens gaskets. Water tends to run forward under the back seat cushions then the vehicle is braking so maybe that's why the rear seat is wet? Let me know what you find, thanks.

      hi. I have a Citreon C1 that is leaking when it rains on the passenger side foot well - the floor is damp in a central position but slightly nearer the door. It is not coming in through the wind screen seals as I covered all the car with plastic the other night except the windscreen and grill and the car remained dry. Take off the plastic and when it rains the car is damp. I have had an extra seal added by citreon over the existing seal at the top but the car is still leaking. They have said the existing seal is good and is making good contact all the way round. Any ideas ??

      Hi Jamie,

      You can find my contact information by my photo at the top of the article on each page. If the water is coming in from behind the door panel, most likely the vapor barrier is compromised behind the door panel and needs to be sealed with new sealer, maybe a new vapor barrier as well, it's a dealer only item or you could use a thick mil garbage bag, trim to fit and seal with dumb dumb.

      Hi Eddie, I have a 2012 Hyundai Elantra Limited. After a few recent rainstorms my carpet on both the passenger side front and driver side front were wet. Took the car to the dealer and after their diagnostic they determined it was a clogged drain from the sunroof. The mechanic claimed that he also blew out the ac drain. Now a week later it rained and of course carpets are wet on both sides again. I've never had an accident or replaced the windshield glass or any glass on this vehicle. Any suggestions as to where you would look? Thanks.

      Hi, Eddie

      I have a 2002 Honda Civic and it's been in the mornings, when I notice my driver's side under dashboard being wet and not the passenger side and recently I notice the passenger side being wet and not the driver's side. It's not all the time. I don't run my AC or my heater and I usu notice this in the mornings. I'm not sure if it rained at night but one day we had a torrential downpour all day and there was no water leak. I do park on the grass at night and I can only think that it has something to do with tho inside of my car has been quite wet. I don't have any smell in my car. Any ideas are appreciated.

      Thanks!

      Hi Eddie it’s coming in via the door. Seems to come in when car is parked when the driver side is parked on the road side at an angle.

      Do you have an email address and I can upload photos as they say a picture speaks a thousand words?

      Cheers Eddie

      Hi Jamie,

      I don't know where the water is entering so you'll need to figure out if it's coming in from the door area or if it's entering from under the dash, like near the windshield.

      Hi Eddie I have a Peugeot 5008 and water is leaking into the driver side foot well.

      The door seals have been recently replaced and the garage where I bought the car are unable to replicate the issue.

      The issue has came back today and seems to come over the top of the seals and into the car. Seems to be more apparent when the car is parked at an angle.

      Do you have any suggestions as hot spots as to where the issue may be coming from?

      Kind regards

      Jamie

      Hi Kaven,

      The vehicle should still be under factory warranty 3 years 36k miles. I recommend you bring it to a Toyota dealership to have it checked.

      Hi Colleen,

      Remember, water runs to the back of the vehicle when driving. Has the windshield ever been replaced? Is there a sunroof?

      Hi Jenn,

      Yes, check the AC drain first for a blockage.

      Hi Peter,

      Try using a coat hanger wire to clean out the AC drain. Is the passenger side wet also? If not, it may be the windshield seal.

      Hi Eddie,

      I have a 2006 Honda CRV and water is dripping down from above the gas pedal when it rains. There is quite a bit of water after 2 days of rain. Do you have an idea of how it is getting in or how I can fix it?

      Advice please. Water (clear, no odour, no taste) is visibly dripping onto the passenger side floor while the car is operating, mostly when during turns. Enough to fill up the grooves of the rubber matting. Wondering what is best to check first ... ac drain? or ??

      FYI - Car is 2008 Kio Rio 5

      Hi Jill,

      Are the carpets wet? is there a sweet smell in the vehicle? Do your windows fog up with the heat on?

      Hi Patty,

      Maybe there is a disconnected sunroof drain or a leaking door seal? Sunroof drains usually are located behind the rear doors in the trunk quarter panel area and in the "A" pillar and out the front fender near the front of the drivers and passengers doors.

      Hi Ron,

      Water runs usually from front to back. I recommend pulling back the carpets in the front and putting a hose on the windshield, then go inside the car with a flashlight and see if you can find the point of entry.

      Hi,

      I have a 2014 KIA Sportage and when it rains the carpets on the floor in the back get wet. This happens on both sides. The door seals seem good to me. One time when it rained I got in the car but, could physically see the water coming in. The last time it rained the front carpets were wet. Original windshield and the car has not been in an accident.

      Any ideas of where the water is coming in? Any help or suggestions would be greatly appreciated.

      Thanks,

      Ron

      Hi Char17,

      Has the windshield ever been replaced? Is it only happening when it rains? Are you using the air conditioner? Is it humid where you live?

      Hi Eddie,

      Is the complete carpet wet? Is it only wet on one side? What kind of vehicle is it? Was the windshield ever replaced? Are you running your air conditioner? Is it humid where you live?

      Hi Kim,

      There are no holes in a transmission case, it may appear to be a hole, but highly unlikely. I recommend having a mechanic put the vehicle on a lift to inspect the leak, it's possible it a minor leak like an axle seal and a quick fix.

      The water in your car, is it only in the back seat area or is the floor wet up front as well? Water usually travels to the rear floorboards even when the water enters in the front of the cabin.

      Hi Janice,

      It sounds like your windshield may be leaking at the top and bottom. Have you ever had it replaced? I recommend having it checked by a glass company first. Let me know what you find, thanks.

      I have a Chevy Malibu bought new in 2011. We had rain last night. On the driver's side where the sun visor is leaking and also in the center front where my sun roof button is and is also leaking under the driver's side dash board water is dripping down and the driver's seat was soaked. I did not see any water spots anywhere else. Any suggestions as to who I should take my car too, glass place or mechanic?

      Hi John,

      First of all the dealer you're buying from (if it is a dealer) should fix the water leak before you buy it, I also recommend running a carfax on the vehicle to see how serious the accident was. It may not be a good buy because of the two key features you pointed out, "the car is perfect" and "the price is right" Do you homework first, water can cause serious electrical and rust problems. Keep me posted, thanks.

      Hi John,

      It's possible the bottom of the windshield is leaking which is very difficult to pinpoint the leak.

      .

      We were buying a car yesterday.passat cc 2009.it doesnt have a sunroof.They found a water leak in trunk at spare tire and said it's because of a side passanger side read accident repair. rubber insulation is perfect,tail gate,windshield,etc.

      they said it might be from the accident, The car is in perfect condition other than that and the price is right.

      any idea what that might be and should I take the risk?

      I appreciate this page so much.

      Hi, the driver and passenger floor of my 2004 Toyota 4runner gets soaked each time it rains or when I wash the car. I've had the sunroof drain checked but problem is still there. Where else can I check?

      Hi Ann,

      The doors have drains, so if the water is not draining, they are clogged again. I recommend taking it back to the same mechanic to have them clean the drains again.

      Hi Jan,

      Most likely you'll need to have the windshield replaced and resealed.

    • eddiecarrara profile imageAUTHOR

      Eddie Carrara 

      9 months ago from New Hampshire

      Do you have a sunroof? The drain for that corner of the sunroof is usually located in the passengers rear quarter. I recommend checking to see if it is connected to the drain.

      Hi Jelena,

      Either water is entering into the fresh air intake of the HVAC system or the windshield is leaking. Have you ever had the windshield replaced? How long have you owned your car?

      My Chevy tracker has been great SUV, but a few years ago, my head lights began to mysteriously come on. Sometimes there would be a clicking. Then I noticed it wasn't just the lights, but the defroster would run if in the on position when the ignition was off. Replaced the ignition, thought that fixed it. Happened again, put that it was only happening when it rained. Now believe it's the windshield that I had replaced about the time it all started. Last winter I noticed the rubber around my window was pooping up in areas. I believe it's a small leek that gets to the fuse box. Dose it sound feasible or am I a crazy woman and do I need to change the ignition again.
