Default Water / rain leaks - C4 Cab - I searched!

The search had lots of sunroof drain references, but not much came up concerning the cabs.

Both the left and right rear footwells are pretty well sopping with water after all the rainfall we've been having. The fronts are very slightly moist. The passenger rear seems to be the worst.

I opened the front trunk and found that there is a lot of condensation around the area of the "shut off valve" above the fuel tank. But the rest of the trunk seems fairly dry.

I couldn't find any significant areas that water could be entering. Are there any usual suspects to check out?

Thanks!

To begin with, these cars were never weather proof...

Seals, seals, seals... they shrink with age...

I would start with the one around the top of the windshield frame... if it is bad you will get drops of water falling in the front carpet... Then you have the ones in the top... the ones in the side of the door have some level of adjustment to bring them closer to the door window. Not sure about the ones on top of the door window as I have not touched those...

Mine also leaks around the front when it rains heavily. I was going to try Jaime's advice and replace the seal above the windshield.

This is a very common replacement seal on the 911. This is the seal that runs across the top of the windshield, and also down the sides. It is a one-piece seal that often breaks in to three pieces at the corners of the windshield. 911-799-565-80

You also have the seal that attaches to the cabriolet top and seals it to the front part of the windshield seal. 911-561-244-01 then you have the small rubber cap that attaches to the top of the small triangular vent window frame 911-542-065-41 / 911-542-066-41

prices for the above are yet not crazy...

Now, these seals are expensive as @#$@#$@#, so replacing might not be an option so try adjustment (#12,13,14 in the diagram)...
Roof frame sealing (on top of door window): 911-561-187-00 (L) / 911-561-188-00 (R) and
Roof frame sealing (on top of side of door window): 911-561-681-01 (L) / 911-561-682-01 (R)



Also, forgot to add... if you do not treat the top, with time, it will let water through... make sure you use the spray that comes to treat the fabric...

Thanks for the tips - I'll start with the seal at the top, then move on to the others. I'm not seeing anything drip-like anywhere, just wet floors.

See if you can go into one of those touchless car wash. That would be the best test to see where the water is coming in from... that way you don't change the seals that are fine. Why waste $ if you don't have to?

This can't help - I just discovered that I'm missing the #85 seals completely. Those babies don't look particularly easy to replace either. Also the #86 seal has a mighty gap on the passenger side. I am not impressed at the shop that replaced the top under the PO...

Nick,

I had a similar problem that was eventually solved. See this thread https://rennlist.com/forums/showthre...light=wet+feet

Good luck on the repair.
