Hey guys I noticed today that my rear floor mats in the back were wet anyone know how to seal it correctly. Going to figure out exactly where it is but when I do how do I go about sealing the leak?

There are 502 reasons why your floor mats would be wet. The t-tops account for 3 of them.

Is there something that makes you think it's coming from the top and not the window or the hatch?

Figured out where it's leaking from, if you're looking outside at the passenger door the leak is coming from the top left corner of the window

You'll want to make sure you don't have this common problem that usually leads to that type of leak: https://ls1tech.com/forums/general-m...dow-guide.html

I'm pretty sure it's the rubber lining

Unless someone tried to break in to the car or a dog chewed on your door, the rubber is fine. Problems arise when the glass doesn't contact the rubber in the right way.

This only leaves something in the door being broken or out of adjustment.

Talk about coincidence - My 02 TA just started leaking at the same location as yours. It's been raining here all week, fairly hard, when the car is in motion is when I'll see the water coming in, onto the rear hatch passenger panel and then of course, running down.


Lets keep each other posted on the progress, and hopefully we'll both get our rides leak free by the weekend.

Same over here, lots of rain !
How are you going about it ?

Process of elimination I think:
- Last night I ruled out the window, for the passenger window seals better than the drivers side does.

- Tonight I'll investigate the weather-strip drains.

This would make sense on a framed car window, but not on a frame-less window, like we have on the F-bodies. The ONLY things that govern how the glass contacts the weatherstripping is the door hinge/strike, hardware attached to the glass, the hardware attached to the door that interacts with the glass, (in our case, it actually pushes the glass away from the weatherstripping) and the adjustment of all the above.

I guarantee water is not getting into my passengers side area from the lack of the window not sealing enough to my weather stripping. It's coming from someplace else, tonight I have more time to pin point the problem.

I had you confused with the OP.

Well in the mean time, anyone how the best way to get rid of the mildew smell out of the carpet?

- I've verified my t-top "flaps" are all seating and sealing correctly. Here is a great write up with pictures on this issue: https://ls1tech.com/forums/general-m...t-top-fix.html

I've found my problem, and it's probably the same for you!

There is some foam sealing tape under the weather strip, back of the t-top area, right where the small bolt is holding the strip down.

Mine is all but gone, and creating the leak into the car. There is more of the foam sealing tape down lower on the side, at the screw holding the weather strip in place.

Tomorrow I'll clean those areas and re-seal with some weatherstrip sealant, and hopefully fixed the leaks.

The rear hatch is definitely a possibility if the car is parked nose down in the rain. Feel under the rear seat bottoms, if that's wet it's most likely coming from the rear hatch. This is a very common problem with these cars and there are multiple topics on here about it. Hope you get it figured out.

Id love to start figuring out where the leak is coming from but it's been torrential Raining for the last 2 days and don't have a garage !

At least I have a few options to check !

Thanks guys I'll keep you posted

This weekend I pulled part of the pass weather strip off, and found the 2 areas GM had used some foam sealing tape.


I removed the old stuff and cleaned the areas, wasn't easy but got it done.
Then I applied black RTV sealer in the same areas, screwed and bolted the weatherstrip down, locked the t-top in place to help keep pressure while it dried.


A day later it all looks good! We'll have more rain here next weekend, that'll be my test.
