Wet Floorboard! Tried everything!

(Click here to view the original thread with full colors/images)

Posted by: 96hotrodlincoln

Ok guys

I have the typical wet passenger-side floorboard. I've resealed around the air intake tube, except for the backside, cause I wasn't able to get to it. I've replaced the piece of weatherstripping on the underneath side of the passenger-side wiper cowl. Checked the drain hole for the AC system, drain seems to be clog-free, couldn't get anything to come out of the hole. I didn't try pouring any water in the intake tube to check the drain. I thought that might be a bad idea.

Any suggestions my friends??? I'm tired of the wet floorboard! Also, the rubber grommets in the floor are intact. Also, not the door seals, plus I have no sunroof.

Sure it's not the heater core? Is it water or coolant?

i just start pulling stuff out till i can see the leak, it could even be a spot on the firewall where it wasn't sealed properly from the factory

Just rain water, not coolant!

If you've been running the ac when you noticed the wet floorboards then check to make sure the condensation run off from the evaporator is actually comming out of the drain and dripping onto the ground, not running back down the drain and back into the firewall to the floor

Haven't been running the AC yet this year, check the drain hole and it seemed to be unclogged, I've had that issue with another ford in the past. We had a nasty storm Saturday night here, rained like crazy, that's usually when I notice the leak.

my suggestion would be to take a real close look at the window sill trim seals that sit long the glass at the bottom, when they dry out water runs down the glass and into the interior of the door, they usually cant drain fast enough when it gets bad and water backs up and runs out from between the door trim and the metal backing onto the floor, or perhaps the sun roof drains are clogged

^ What he said ^

Gotta think it's a leaky windshield if it's rain water. Maybe the windshield was replaced in the past..?

I don't believe that the window sills trim seals are the issue, but I will check it out anyways.

Windshield was just replaced about two months ago, although it leaked before it was replaced too. Although, it wasn't quite as bad. I'm thinking, maybe it was an issue before the windshield was replaced, that just got worse after. I'll either wait until it rains next time and watch for the leak, or I'll start tearing it apart and looking for questionable seals.

Water can come through the vent under the wiper cowl if it's not pressed to the windshield close enough.

Some RTV between the glass and the cowl can help.

the only reson I brought up the window sill seals is because it happened to my dads old towncar, when it would rain hard the entire back passenger floorboard would be under water lol

i will have to say that since you didnt seal behind the air cabin vent under the wiper cowl that is most likely the problem, i know you can get behind it, but, this is what you can do, take the wiper cowl back off, and cut around that vent, take it right out, clean where the base of it sat, then run a bead of seam sealer around the base of the vent and squish it back down in place, use a thick bead dont be shy no one can see it, i have done this to stop leaks in a few of my customers mark's, i took it off completely and sealed the flange itself then squished it back down, real hard, let the sealer squeeze out then take your finger and smooth out the excess with your finger around the flange as much as you can, getting behind it is very hard, thats why i say to put the sealer on the flange it will help get it behind the vent. try this, i bet your water leak goes away.

I wasn't even aware that the tube came off, I figured it was permanently attached to the air box. I was figuring it was the back side of the vent cause I typically park on a slight uphill incline. I figure the water is sitting in behind the tube and leaking in there somewhere.

If what Jamie suggests that doesn't work...

OK? Does it get parked on unlevel ground, like at the curb? My 94 will leak when it rains if parked on the curb, and she'll leak good.

If parked on flat level ground no leaks.

Took it to a auto body guy and he suggested that a drain, hole which is supose to allow water drain, may be plugged with leaves or other debris.

I searched for this hole which is right above the front RT 1/4 Panel but what I found was not plugged.

So I try not to park it on the street when it's going to rain to avoil any water.

Car does not leak when I wash it either. Only when on unlevel ground leaning to the passenger's side.

I had the same problem with my gen2. I fixed my leak by just replacing the plastic screws on the cowl which were not really holding much of anything. to my astonishment, one was missing and the other hole on the driver side cowl was resting in place on top of the screw hole w/o any screw inside! i just replaced them with real screws and colored the heads black w/ a marker for looks (didn't work out as well as i'd hoped). I did this last night and today it poured here in NY by the buckets and the carpet was dry. hope this helps. I warn you however, you may strip the tread where the previous plastic screws once were. i do not know if that can be replaced or not. any info would be appreciated, b/c i'd rather have original stock look than a frankenstein mark. lol

I'm considering using some of these if they will work, and trying to find some black screws, or just getting a can of rustoleam and painting them black. They're called U-clips and can probably be purchased at the local hardware store.
