Water leak on Driver's side door

[lelandschultz]

I have a '93 coupe and have had all of the weatherstripping replaced (by a Chevy dealer with OEM parts). When washing vehicle I get water leaking inside near and getting the carpet wet about in the middle of the speaker. The carpet just below the plastic panel on the (the panel you can't see when door is shut) is also wet.
Any suggestions???

I'll be watching this one too, seeing as how I've had the same problem for years - and I also replaced all of my weatherstripping. Yet, the leak persists.

I'd go right back to the dealer and tell them; make them fix it. Your window probably needs adjusting and they may sell you some parts that support and guide it, if or no other reason than to absolve themselves of any wrongdoing. Adjusting it is a bit of an art, I think. Watch carefully as the window closes the last bit to observe how the glass seats in the rubber.

Reminds me of having my steering wheel replaced at McPherson Chev. After, the telelscoping part didn't lock it very well.

I change all my wx-stripping, but the few washes I do, invovle little hard spray 'above the belt'. I know the likely leaks will be at the junction of the windscreen, top and window; was the first leak as the car aged.

The water leaked prior to the dealer putting in the weatherstripping so they are not at fault. They thought the driver's door may be a little out of alignment but otherwise were not sure as I have also replaced the outside window guides.

As you seem to have a good repoire with the dealer, you might go back and ask them why the new weatherstripping leaks. Such is one of the functions of these expensive parts.
OR
Sit inside the car and have someone squirt all around the window with a nozzle, similar to conditions which cause the leak. Moving the nozzle slowly and varying the angle of incidence will help if the leak is not readily apparant. Water will travel, which can make detection harder. This process can be painstaking, which is why few dealers care to do it.

My leaks are at the junction of rubber pieces at the top corners of the windshield. As your wetness is under that area, you might spend extra time on it. The rubber under the top can flatten and leak, as well.

I won't claim to be a door adjusting expert, but inspection of the striker plate can be a good indication of a sagging door, as the hinges wear.

I still think that closely watching the window close, from the outside of the car, will show if it shifts in the last little bit of travel. Considering that you replaced the guides, it's a good candidate for your leak.

Good luck.

Mine seems to leak from the top corner of the windshield and runs down the windshield frame and looks like it is from the door weatherstrip. I replaced the windshield strip which reduced the leak from literally pouring in to a few drops and then only when it rains really hard.

I have a similar leak as "lelandschultz" above. I read through the factory service manual and followed it to find the leak. It says to use soapy water (409 in my case) to spray on the outside, and use an air hose to spray from the inside out, looking for bubbles. Start down low and work your way up with the soapy water. I removed the windsheild garnish trip to be able to see everything and to get in close with the air hose. Found my problem to be the seal between the windsheild trip moulding, and the metal strip that holds the weatherstrip. It looks like it is all one piece, but it is actually two parts. The book breaks it down to show all the parts.

Now I have to decide if I can take it apart and repair it, or if I will need to replace the weatherstrip at the same time.
