The past few days it's been raining, and my car has sat outside overnight. Every morning, I find a large puddle of standing water in my passenger side floor. I have no idea where it's coming from, but my first guess is the winshield? My inner fender wells are out, I don't know if that has anything to do with it. Any ideas??? Thanks

 

Do you have t-tops? If so, is your headliner still attached? Before I installed my new one, I used one of the lead detection methods from GM's 1987 shop manual.

If your headliner is off, this will be easy. If not, I would lower it in the middle section. Then, take a bottle of dish detergent and with the t-tops ON the car, run a bead over all the top of all the parts where the glass meets the body.

Next, from inside of the car, use an air compressor nozzle (or a power tire inflator if you don't have a compressor) to shoot air all along the joints from the inside. Anywhere you see the soap start to bubble on the roof, is a potential leak spot. This method worked perfect for me; I now have 7 areas to treat on my driver's side.

 

Yeah, I do have T-Tops; I'll defenitely be sure to try that out. Thanks! Whats the best way to go about fixing the trouble spots?

 

Is the rubber in good shape?

Some ppl use windshield caulk that comes in strips.
I D K how to use it.
Somewhere I added a link to a magazine editor installing new weather stripping to his T-Tops.

Maybe search 1ATony for the link 1A Auto has showing how to install T-Top stripping. It will at least give you an idea how it's installed.
Also, search t-top leaks or t-tops leak--that is where you will find ways ppl have successfully stopped the leaks. There are quite a few, so happy browsing!! Other wise, I would post a link. Find what fits your situation.
I used clear silicone. It worked for a while, but NOT permanently!!
Washed the car last week & : ( little bit of a leak!!
Some ppl will tell you it's just the nature of T-Tops!
Good luck, & post your fix!!

 

I haven't tackled that yet (having a garage and therefore, a dry car, is definitely a procrastination factor)! But, I found some good posts after searching the site; specifically threads with photos showing where and what was done. * For all of you reading this who have done t-top leak repairs, feel free to paste the links here to your threads
