Hi All!

I have been working on my XJ-S and pulled out the back seat. To my disbelief, on the driver (left) side I found a puddle of water. The seat foam (bottom part) was also wet. Additional searches found that the carpet and pad on the left rear were also wet. My door seals are all good. No visible rust anywhere on the car. I found this after snow had melted off. The car was parked in my driveway that does have a grade to it, and the front was pointing downward in the driveway. Any guesses as to where the water could be leaking? Thanks in advance for nay thoughts and ideas!

 

You mentioned snow, so this maybe wrong time of year for this. Can you pull the rear seat and have someone hit the top with water. I would suspect the rubber seal in the back glass. Check in the back pillar down the side of the convertible top. I also would consider making a small drain back there for the water to escape. Good luck!

 

Which car?

 

1989 XJ-S Collection Rouge

 

It's actually not the convertible that is leaking. I should have mentioned that in my post. It is my Collection Rouge that is leaking.

 

In that case the water is either coming through the rear window seal or the fixed side window seals. In the case of the rear window, sealing round the rear window rubber/metal body join is the best and cheapest fix. All the way round, including the bottom. Use bitumastic sealant, push it in with a sliding finger and then clean it up with white spirit soaked cloth.
Side windows: on the outside, seal along inside the rubber to window seal all along the vertical and bottom edges. On the inside the same AND seal between the rubber seal and the bodywork.This has worked for me for decades.

 

I'll give that a try! Thanks!!
