Water Leaks -- How to Find and Fix



  • rderrder Posts: 1
    I have an Accord EX 2000, which has the same problem. The trunk seal looks perfect, but the rain water comes into the trunk through a hole near the passenger side speaker. I saw water gushing in when snow started melting after the major snowfall on the east coast last February. Water collects in the spare wheel well, outlets of which I have had to unplug to drain out the water. Since it was covered by mats etc., I didn't realize until I lifted up the mat one day and saw rust in the well. I don't feel any moisture in the car back seat or anywhere, bu the inside of the car fogs up unusually.

    Did you get your car fixed? How and where? What was the problem? And how much did it cost? I would appreciate you or anybody letting me know. Thanks

    I have a 1998 Ford Explorer XLT V6 SOHC which leaks water on the driver's side floor whenever it rains. I see the water comes down along the firewall inside of the car. There is some sort of black rubber possibly for protection in the event of a fire covering the firewall along the interior of the car. It seems like a lot of disassembly might be required to remove this rubber intact. I would appreciate any suggestions in locating the cause of this leak and fixing the leak. If I pour water down the plastic grill in front of the windshield I see water leaking into the cabin along the firewall. Is there any sort of drian that could be clogged? It also occured to me that maybe some area of the metal below the plastic grill rusted and is letting water through.

    When I pour water on either the passenger or drivers side grill in front of the windsheild the water seems to come out in multiple places along the door and below the car. Not sure what is supposed to happen exactly. Any suggestions would be much appreciated. Water does not seem to leak in on the passenger side.

    I have a '99 Ford Expedition that has an annoying leak that appears every so often on the drivers side after a good rain. I have actually had water to pour in a stream on my foot while it was on the brake pedal. The water doesn't show nor does it cause problems every time it rains, it will usually cause problems after a couple of days to a week after the rain. The fuse box will usually get wet which causes everything to malfunction(defroster running,wiper blades starting/stopping,radio turning on/off,security system engaging-all without the key in the ignition,slow start/or not at all). I have had my windshield replaced and even resealed as I was told that the windshield was the source of the problem. However,this did not solve the problem!! I have replaced the fuse box twice, which can get pretty pricey. I was recently told that it may be a body seam and that I should go to a body shop and have someone take a look at it. After making a few calls, it appears that everyone that I talked to is a little hesitant to even take a look at it. This vehicle had been wrecked before I purchased it. I am desperate, please help!!!!!!! :cry:

    Not sure how anyone can really help via the internet. Sounds like to me that whoever put the vehicle back together after the wreck, either left off a gasket, or didn't close a weld, or they could have mistakenly closed a drain, or something else like that.

    It's going to take a lot of hands on sleuthing to try and determine what is causing the problem. Your problem is undoubtedly complicated by the fact that it was wrecked. The bad thing is, this water is going to ruin your electricals and cause many other problems down the road. You're going to need to fix it, or dump it.

    A drain hole in a pan that's under the evaporator coil is clogged up somewhere.
  • I have the same problem with my 2002 Vue too. I want to get it fixed but am not sure how to do it.
  • The repair work was covered under the extended warranty, so I do not know the cost. However, the Honda dealer did keep the car for a week to perform the work.

    Just to recap, the leak was from the sunroof which was not draining properly and leaking into the trunk and cabin.
  • Hi Rainchaser,
    Could you possibly let me know what I would be looking for? My neon does not have a sunroof. I have had to remove my back seat all together, as the water seems to be leaking near the seat belt lock... please send me responses to
    Any helo is greatly appreciated.
  • I have the same issue..I know the water is coming in from the back seat near the seatbelt lock.. as I have taken out my seat all together... any advice?

    Have you tested for leaking tail light assembly? You ca spread some newspaper in the trunk, then close it and spray the trunk and tail lights with a hose or car wash wand, then open the trunk and see where/if the water is coming in. If it is the tail lights, it's not the gasket around the lens itself, but rather the seal around the entire body of the tail light assembly. Sometimes you can tighten this up with thumbscrews provided, or you might have to seal it from the outside with some clear LATEX sealant, which is water-soluble and not messy like silicon

  • My 2001 Lincoln Towncar has a terrible water leak both driver and passenger side. I had a window glass installer check and he claimed no windshield leak. I removed the cover and cleaned the tray under the windshield wipers but still get soaked carpets when it rains. A couple years back I had the wiper motor replaced...nor sure if there is a gasket or seal there that is the problem. Car windshield frosts up on the inside from the moisture inside the car due to the damp carpets. I place towels down under the mats and they get completely soaked. Top of the mats are dry. Any help is greatly appreciated.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,604
    When you cleaned the tray under the wipers did you also check and clear the drains under each tray? You should be able to test this by pouring a shotglass or two of water in there and you should see it dribbling on the ground.

    Thanks for the reply..I have free flow of water from the three drain holes in the tray area (left middle and right side) water runs out to the ground. I used silocone sealer around the screened vent in the tray that is in front of the passenger side. (often cited as the cause of leaks on the passenger side). It rained eariler today and the towels under the mats were soaked again. I can't understand how the water is getting into both sides of the interior. Any other thoughts/advice is greatly appreciated

    How hard is it to remove the floor mats - down to bare metal? If you can do that, you might be able to locate the approximate source of the water - see if it's dripping from the center of the dash, running down the inside of the firewall, or down along inside of the car (the parts that are usually covered up with carpeting).

    Do you have a sunroof?

    No I don't have a sun roof. A prior posting suggests that it might be a leak where the hood release cable goes through the fire wall? Any thoughts on that and how to fix. Lastly,,, a couple of years back I had the wiper motor replaced. Is that located where a leak could occur? If a possible source of the problem...any ideas on how to fix that... Thanks all.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,604
    Well I suppose the wiper motor didn't seal too well against the firewall--but gee that's a long shot.

    So have you ever tested the windshield gasket, using the newspaper method I outlined (laying down newspaper on the floor prior to the test, or against the firewall inside the passenger compartment?)

    Have you ever had the door panels off on this car for a repair?

  • I have water building up inside my car on the driver's side ceiling between the window & windshield. It becomes saturated after raining & then a small drip starts which ends up getting my seat wet. I had it checked by my insurance agent who said it is not covered but suspected it was a windshield problem. I've had it checked by 2 glass guys who said they cannot tell till they remove the old windshield & even if they replace it, that still might not be my problem. Is there an easier way to approach this problem? Thanks to all that reply.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,604
    Why don't you read back in the topic a bit and look at suggestions for sunroof leaks and for leaks from the fresh air vent cavity under the wipers?

  • I do not have a sun roof.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,604
    Okay then...there are drains in the cavity under the windshield wipers--where the fresh air comes in for the car's interior. If any debris, dried leaves, junk from trees, gets washed in there by the rain, eventually this organic matter forms a kind of plug in the drains---then more rain comes in, or melting snow, and you've got a little fish tank in there.

    What has to be done to check this is to remove the cowl plate below the wipers and peek in there and see if there's water accumulating. The drain itself usually ends up as part of a rubber tube that sticks out of the firewall and drips /drains onto the ground beneath the car---but of course if the drains are plugged, it's going to leak into your car.

  • My leak is on the CEILING. Would a plugged drain in the cavity under the windshield wipers cause leaking that far up or would that just be found on the floor?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,604
    Oh no...I didn't catch that part. So you have a leak on the headliner and you don't have a sunroof? Is that right?

    And where exactly do you think the leak starts? Is it near the front of the headliner, or on the side, or.....

    My only guess at this point is that a roof leak on a car without a sunroof as either got to be a windshield seal leak up top there, or if not that, then a leaking seam where they didn't weld it properly.

    you might have to drop the headliner in that case.

  • When the area becomes saturated, you can feel it almost all along the area just above the side window all the way to the windshield. The wettest point is in the corner before the windshield. When there is a lot of rain (which we've had) it becomes so saturated that a drip of water starts & that's how my seat gets wet. I just wonder if going to all the expense of replacing what looks like a perfectly good windshield may end up being a waste of time & money and in the end the origin of the leak will be in the area above the side window. It's like exploratory surgery. I'll just be having guys replacing stuff till the leak stops. It seems like there should be a more efficient way to solve the problem.

    Have Honda Accord 1995- recently, when I pulled the rear passenger side seat belt, got water on the seat. There is water in the trunk too- seems water is entering from the underbelly- any ideas?
  • srs_49srs_49 Posts: 1,394
    What makes you think the water is coming in from below the car?

    I would look for a bad rear windshield seal, or a dried out/cracked gasket between the trunk lid and the trunk.
  • Would it be the same for a Chev. HHR 2006 we have like a mine lake inside ?
