What causes a 1995 Chrysler Lebaron convertible to leak water when it rains puddling on the floorboard both front and rear driver side?

Answer 1

I had this exact problem and there is more to the problem than just an old top. no convertible top is ever water tight no matter how old or new the top is. in the bottom of the rear window wells there are two small drain holes that allow any water that has gotten in to drainout of the wells. however these holes are rather small and can become clogged with leafs or other debris. when this happens the wells fill with water and this flows forward into the hollow box frame of the car where it is attached to the window wells. now the problem that you incounter is that the seat belts for the car have had their mounts drilled into the hollow box frame and this is where the water comes out of after the frame fills up. what i did to fix this problem was to clean out the leafs and debris. then I drilled the drain holes larger so they would drain better. after this i took out the seats and seatbelts along with the carpeting and then I used "Great Stuff" foam filler and pumped it into the box frame through the openings in the frame to seal it off from the window wells. (this product can be bought at any hardware store and is water proof). the larger drain holes and sealed off box frame will solve the flooding problem alltogether. ^^ It's either due to the top shrinking with age or an incorrect installation. Look at the corners of the top where it meets the body by the 2 rear windows. I bet you can put your finger underneath there. The water runs down into the body by the rear windows (that's what kills the windows motors, btw) and then it puddles in the rear floor. Check out the side bow where the drivers window comes up. The top should wrap down tightly and cover that. If not, water weeps into the front and runs down the weatherstrip.

Spray foam will cause your car to disintegrate. It works like a sponge and absorbs it. Never use spray foam around metal when it can be exposed to water in any circumstance.
