Default Water leaking through the passenger window

Water is leaking in my 2001 911 C2 Cabriolet. It is leaking through the passenger window by the top by where the windshield is. I am not sure exactly where it is coming in.

It leaks both with the soft top and the hard top. I see water in rain and at the car wash. It sometimes fills up the pocket at the bottom of the doorsil.

What can can I do to troubleshoot this?

Maybe try cleaning out some of the drain passages in case they are clogged? I wonder if it is a worn seal? You could test it with some water and try identifying where and how the water penetrates. you can do the same to test the drainage flow out of the drain tubes to check for obstructions that maybe preventing the water from free flowing out.

Make sure the cabriolet top is parallel to the top edge of the windshield before the cab top locks down (that the alignment is correct).

Check the drains as Device2 suggests...if this persists, your problems are going to get a LOT more expensive if the in-cabin control modules get wet.

Have you had the door card off? Maybe the membrain has lost its seal or your door drains are clogged?

One, stop going to the car wash in a cab. The water pressure is too great and something is going to leak. I would check what others have said but i would also take a garden hose, have someone sit inside in the passenger seat, and run water over various parts of the windshield and door window/seal. There is a rubber seal surrounding the windshield and with a cab, various seals along the top edge. Have you very closely inspected those? If the leak is somewhere around the door window, there are adjustments in the lower part of the door to move the window so it makes a tighter seal with the cab top.

I went to the carwash with the hard top on. I just picked up this car. It was parked outside with the soft top when I purchased it, and I observed the water passenger side doorsill container. Is the water pressure at the carwash too great for the hard top as well? I think it leaks even on low pressure. I will have to use the garden hose method to test it out.

Where is the in-cabin control modules? Can I seal/waterproof them, so that they are secure from future possible issues?

I'm not 100% sure that the layout is the same for the cab vs. the coupe. In the coupe, more of the electronics are moved to area that houses the convertible cassette - so I think water is potentially a greater issue for you and your cab vs. me and my coupe. If the cabin gets waterlogged enough that the electronics under the driver seat get wet, you have a very expensive problem on your hands.

There are solutions for waterproofing, including this waterproof enclosure from ECUDoctors.com:



Ensuring the drains are all working is the cheapest solution, even if it's not the most permanent solution or the most effective for all situations.

i hope I'm not hijacking the thread. But I was wondering what would happen if you didn't have the water drainage tubes connected underneath the front water collection tray? I mean it would still drain and not overflow? Why I ask is because I managed to get one of the drainage tubes lose underneath the bottom of the collection plate trying to clean it. I have no means of getting it connected again, but the water seemed to drain out on the ground underneath. No damp interior afterwards.

So all in all, do the front collection tray drainage tubes really need to be in place it it drains out on the street anyway?

regards

The front collection tray? Carl, do you mean the area on the left or right in front but behind the frunk? BTW, some models have those drain tubes removed and replaced with this type of drainage grommet. Short version is P/N: 171819419 and long version is P/N: 91102561200.

The water drainage basin and its drain tube should be intact.

Briefly, the basin collects the water and the drain tube is there to ensure the water goes where it can do no harm.

If the drain tube is damaged/missing the water has to find its way to the ground any way it can. This could have the water running down other surfaces and not reaching the ground but instead flowing onto things it should not or into areas it should not.

This is just with the car stationary. As the car moves down the road in the rain the air flow under the car can have this "loose" water flowing anywhere and everywhere.

My advice is you reconnect the drain tube to its basin or replace the damaged basin/drain tube to ensure water is routed out/under the car in such a way to keep the water from where it should not be.

Yeah the collection tray underneath the battery, it seems to be a continuous tray. Just in between the frunk and where the bonnet hinges connect. Ill try those rubber grommets!

I went to the nearest opc and asked them about the drainage tubes. According to the salesman who also asked the mechanic, it doesn't matter that much if the hoses are dirrconnected or connected. What he said was that rather them being disconnected than clogged up. (i disconnected it while trying to clean the tubing.)

Make sure that the window is touching the seal at the windshield/window joint when the window is up.
With the window up and door closed on a piece of paper check to see how much force it takes to move the paper in/out up/down all around the problem area. It should be very hard to move without ripping it.
Try the drivers side for comparison. The windows can be adjusted for a tight fit. There are screws under the bottom of the door that adjust the window if needed.

Along the same lines do you have an aftermarket stereo or speakers in the doors?

Most aftermarket places just hack the crap out of your car to put them in as fast as possible, they slice the waterproof door membranes to put in bigger speakers etc.

Spent months fixing junk like that in my old boxster, I swore I'd never buy another car that has been touched by one of these chop shops
