Every time it rains or I get my 2007 C4 Cab washed I wind up with wet carpet at the bottom of both door inners. The drains are open. I spent $1000 on this with Porsche dealer service, but they couldn't find any problem. Has anybody else had this problem? PIA to not be able to drive in the rain!

 

I had a similar problem in my 996 cab. Cleaning all the drainse helped, but I had to replace the seal on the rear quarter windows where they seal to the front window to get it to be completely dry.

 

It sounds like the door seal. I had the same problem, and the dealer sealed it with excessive silicone. They claim it is a better solution than replacing the seal. No more wet carpet.

 

Did you have this in a coupe? Would be possible to post some photos of the location and fix? Thanks!

 

I went through that with my '05 coupe - removed the door panel and siliconed the seal - dry now.
Also replaced all the door switches FWIW.

Had lots of water. had to remove the mats and dry them. Hot afternoons it was like a stem room.

Fairly easy diy if only doing silconing the seal. Little more involved with the switches, but still very doable.

 

See ^ if you want to tackle it on your own. My car is still under CPO, so I just took it to the dealership. It requires removal of door panel and such.

 

The front windows can be adjusted to tighten the fit with the seals. There are four screws at the bottom of the door (covered by black plugs). The screws are in pairs at the front and rear of the door. One screw adjust how far up or down that end of the window can be positioned. The other screw sets the tightness of the fit between the top of the window and the seal. The official test procedure for fit tightness on that seal is to insert a piece of paper between the window and the top seal, close the door and then pull out the paper. There should be resistance but the paper shouldn't tear.

 

Thanks for the adjustment info - did not know that!
