So my car has been smelling a bit musty for a while and I thought it was the T-top or hatch seals. I finally did some testing and searching and here's what I found. Took the car through a car wash and not 1 drop from the tops. Tested the seals around the tops, windows and hatch with a piece of paper and they all seem good. The car has been sitting outside lately and after a long rain I noticed there was water puddled up where the drivers side rear seat bottom should be (rear seats are out at the moment). Seems like there was a wet trail on the carpet from the door to the well. Could this be my door seal?? Car is a 1992 BTW. Also what's the best way to get the musty smell out of the car?? Thanks

 

have you tried sitting in the car will having someone spray it with water?

 

Did you look UNDER the seat? You could have a hole in the floor.

 

I was in the car through out the car wash and nothing came in so I don't think having someone hold a hose would do it. Seems that it happens with it rains all day.

No holes in the floor. I was under there inspecting the under carriage when I pulled the motor and trans for my LS swap. Car is solid.

Has anyone heard of the door seals leaking? Where the door and body meet under the window.

 

My 89 GTA also has a weird leak like that. The drivers side rear seat get a drip from the rear plastic ceiling panel. I have removed it and seen water drip out the hole the screw goes in to hold the panel up too. Not sure how water is getting in and t-top seals in the center near the t-bar are tight. Any suggestions would be fantastic!
