  • Thanks for the post. My mother has taken her 1999 Town Car to the dealership three times to fix the leak that you described, with no luck. My son and I followed your instructions, and after a weekend with 2.5 in of rain, no leak. Thanks again!
  • We have a 01 LTC, bought used. love the car hated the water leak that came with it as a surprise. Went to google typed in problem and this forum came up. problem was fixed right away. This guy was absolutly right. It was a gasket under a grill. Followed his advise and problem fixed.
    Thanks
  • I have a water leak on drivers side an can't figure where it is coming from?The drivers side floor is soaked could it be a seal or weld? Any help would be appreciated,

    Thank You

    could be a seal up top where the window slides into the door...this is called a "squeegee" in case you have to order one.

    Also, has anyone been in the door recently for speaker work or window work? If so, they might have forgotten to re-tape the plastic moisture barrier inside the door panel.

    Another thing to check are the door drains (little holes at the bottom of the doors). If they are plugged, you'll have a little fish tank in there.

    Last of all, a loose rear view mirror can cause a leak.

    I bought a used 2003 Honda Accord Coupe. Every time it rains I find water on the floor in the back behind the driver's side seat. I have had it in the shop 3 times, twice to the Honda Dealership. They said the sprayed water all over the car and found no leak. The last time they said the sunroof drain was clogged and they unclugged it. Last night it rained and I found water in the same place. One day I was in the car when it was raining I saw a stream of water going from the doorwell across the back floor.
  • I bought this accord used almost 3 years ago and have found that every time it rains I have a passenger side floorboard full of water. This is seen both in the front and the back. I took it to a honda dealership and they said that the drains along the windshield frame were not working correctly and supposedly fixed them but the problem still occurs everytime it rains. I even took the car to an auto glass place and had them re-seal the windshield and back glass. The problem remains. Please if anyone has any advice I would greatly appreciate it.

    Could be the following:

    1. Drains in the door itself are clogged.

    2. The plastic membrane that sits behind the door panel may have been removed for a repair and not replaced?

    3. The rubber seal, called a squeegee, is worn/torn. This seal sits at the base of the window as the window goes into the door.

    4. If you have a sunroof, the front sunroof drain is clogged, or a rubber hose inside the car's A pillar (where the windshield is glued in all the way on the right side) has slipped off its tubing.

    5. the fresh air vent (under the windshield wipers) has filled with crud and tree debris and is now a fishtank in there, and needs to be cleaned out.

    In order of possibility, I would check 1, then 3, then 5, then the other two.

  • Hi! Thanks for the info. Your fix was 100 percent right!

    I took my 2001 Town Car to the deler today and they said they had lots of Merc & Lincolns with this problem.

    They preformed the exact fix you told about. They even took out the seats and they are keeping the car tonight and tomorrow drying the carpet. Don't yet know the cost, but this dealer was very helpful, especially about drying out the carpet as I have no garage! Bill E

  • BILL E:
    Hope that does it for you. I realize you have a helpful dealer ... but please pay close attention to whether the carpet is REALLY dry on BACK side where there's a thick foam that's VERY hard to dry.

    I'd sure like to know what your dealer charged $ to pull carpet & seats ... dry it .. and reinstall? Would you post cost $ here or email $ thru this forum?

    the floor of the passenger side -from front to rear - is completely soaked. Driver's side is dry. Can't find any obvious source beneath the carpet. Have cleared out the debris where the fresh air vents are, but still having a problem.
    - what are the likely causes of a leak only on one side?
    - if it could be that the vents aren't draining properly, how to fix? and is there a reservoir in there now that we need to drain somehow?
    - how to dry the carpet once the leak stops?

    thanks for your wisdom.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    Yes there is a drain hole at the bottom of the fresh air vent cavity. You can test it easily by pouring a small amount of water in there...you should see it coming out beneath the car. If it isn't, you'll have to pop open the vent clean out the gunk in there (bio-degraded tree debris, etc.) and unplug the drain hole.

    Another possibility is a clogged sunroof drain (which would drop water from the ceiling) or a dislodged sunroof drain tube that sits behind the A pillar interior trim.

    Last possibility would be a leaking windshield.

    Some fresh air vent systems have a plastic removable tub reservoir in there with a gasket around it. Others are just a metal basin that is part of the car.

  • Hi! Got that leaky Lincoln back from the dealer today. The charge was $197.50 which I didn't think was bad as they fixed the leak (just like your post with the silicone seal) and took out the seats and carpet and dried them out for two days. Lots of labor there! Bill E
  • How do I access the the fresh air vent cavity and the various other drains to check if they are clogged?
  • I have a 97 Honda Civic Hatchback that after it rains there is about an inch of water in the well where the spare it at. The carpet is not we at all and I cannot find anyhwere that it leaks from. If the seal was leaking I would think the carpet would be wet? Anyone have any ideas? I have tried everything that I can think of. There was one post on there that had this problem but, I didnt see anyone answer his question?? Help!! :confuse: :confuse: :confuse:
  • On the floor behind the passenger seat everytime it rains the floor is soacked with water. I've done some inspecting and it isn't leaking from the roof or door seals of seat mount bolts. As the on wet spot in on the fllor in the middle. Anybody heard of this or seen it before, would really appricate the help. Thanks Alot!
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    Try two things:

    IF you have a sunroof, open it and look for the rear drain hole in the groove where the roof rides...pour just a little bit of water in there and see if it goes down to the ground under the car...or...into your back seat.

    2) lay down newspaper in your trunk, especially in the area of the tail lights and where the trunk seal goes 'round...and then test with a hose and see if anything wet the paper. What CAN happen is that water leaks into the trunk, then you brake quickly, and it squishes into the passenger compartment under the seat.

    i have the same problem. the water also collects under the back seat and makes the seat wet. help!
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    Any water in the trunk/hatch area, that might slosh forward when you brake, or are you sure it's only in the rear seat area?

    If it is isolated to the rear seats and isn't coming from the trunk or hatch, and isn't coming from the front seat area, you had better check the rear sunroof drain (if you have a sunroof) or the rear door "squeegee" that wipes the window clean when it goes down....or the door drains...if you shake the door can you hear water in there?

  • i0i0ii0i0i Posts: 2
    yeah, i heard water sloshing when i brake. i checked under the spare tire and there is a tone of water there. any ideas? any help would be greatly appreciated. thanks.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    You could put some newspaper under the tail lights and then test with a garden hose around the tail lights...those gaskets get old and water can easily come in there....also the hatch or trunk seal...you can test by carefully examining the hatch or trunk seal for tears or places where it's come loose. If you see a suspicious spot, lay a dollar bill over it and close the lid. If the dollar bill can be slipped out easily, that seal is not tight enough to keep out water most likely.

  • I have a 99 lesabre and we had heavy rainfall for about 3 days..went to get in my car and my front driver side carpet was wet but it was nothing compared to the back.There was a swamp behind my seat.I guess from where it settled.So I poured water all over the wiper area and finally I saw some trickle down right behind the gas pedal down onto the floorboard.I took the vent off and I dont really know what Im looking for...I dont see alot of leaves on top.Where am I supposed to unclog it from....the top or bottom of the engine?The seal thats attached to the vent is basicly ripped off and Im missing a few of the rivets that hold it down...could water get in those and cause a leak?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    There should be a drain down there, at the bottom of the basin. You unclog it from the top usually, if you can. On some cars, the drain pipe is visible on the firewall, down low. You can also check for various grommets or seals that are broken. If you poured water on the windshield that could also have a small leak. Did you see water pouring out the drain when you tested?

    MODERATOR

  • Yes water came out right under the front driver wheel.I dont think its the drain becuase the water just instantly poured out from the top.If it was the windshield wouldnt I be able to see the water coming in from the inside by the windshield?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    Not necessarily...sometimes the leak can travel to the corners of the windhshield...but that's not where you leak is. Well if the drain is working it must be some grommet or seal in the cowl area, or a body seam that wasn't totally sealed at the factory.

  • My daughter complained about her windows fogging up and a wet rear seat in her 1996 Civic Hatchback. Sure enough, I checked and the spare tire well has 3 inches of water in it that must be sloshing under the rear seat. I am useless at fixing stuff myself and I really trust my car guy, but I don't want to give him a bolank check. I hope that it's the fault tailight gasket like you guys are suggesting. I have checked the trunk gasket and it seems really tight. Have you had any feedback that the tailight gasket turned out to be the problem? Thanks
  • I have a 1987 Honda prelude which has a slow rainwater leak from the windshield which slowly drains into passenger side flooboard from behind the glovebox. I slowly poured water ONLY down the windshield and within 30 seconds, the
    drip started. Most of the water correctly drained behind the right front tire. I tried to take off the fresh air cowlings--but didnt have too much luck due to the age of the car. I even have the service manual for the car and it doesnt reference that at all

    any thoughts or ideas?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    Well usually there are a couple screws holding it in....all cars are different, so......do you know a good body shop that might give you a tip on this?

    Once you're in there, look for a cracked grommet or some loose seal in the firewall area...your drain might be working but might also be backing up a bit...

  • Howdy,

    I recently discovered standing water under the driver seat of my GFs Honda; no work has been performed on the car door in over 6 months (I removed the speaker to check the speaker brand). I have reviewed some of the posts on this forum but need to know if it is possible to have water trickle past the speaker.

    I ask this because, I have dismantled the car (driver side seat, door panel, carpeting, rear seat, and any molding that might hide a leak. The only smoking gun I turned up was the trickle of water from the speaker which was dripped on by the power mirror cabling(with hose applied to driver side door window).

    What is the cause? The squegee type window seal? A leak in the mirror housing? WIndshiled leak? Possibly the vents (but wouldn't my front floor pan, also have standing water)?

    Help. Any advice or just a damn good fix would be greatly appreciated.

    Nick
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,527
    Okay, couple of ideas:

    Did you replace the plastic membrane inside the door panel or did you just tear it out? If it's not in there, that could be your problem.

    If the plastic is in there, how are the door drains at the bottom of the door? Are they clear of debris?

    Yes it could be the squeegee at the top of the door. I think you could test this by removing the door panel and pouring water on the window.

    Usually squeegees just slide out...you just pull 'em backwards toward the rear of the car---but all cars are different...some require removal of a chrome trim piece first, so I dunno....
