Carwash spray leaks down all side windows. We've had since new. Low mileage. Always garaged. Appears to be getting worse. Hints?
Thanks

I have the coupe and because of the lack of b-piller, small amount of water would come in when going through touchless car washes. This is true since the car was new.

The side windows do a quick release when you pull the door handle. I just open before the release is finished so may be damaging the seal?? Not sure if this is the same on the coupe. Any advice?
P.S. note that my carwash has upped the pre-wash pressure to the degree that there is now water on the inside door sill.

I also have issues with the front side markers when going through touchless car washes. I had a malfunction and when I removed the side marker, it's full of water inside. The wiring was all rusted and I had to replace the wiring in the dealership.

My MB advisor said although these side makers have grooves to direct the water when the water is coming down vertically, they are not designed to fend off high-pressured water shooting in horizontally like touchless car washes. Maybe this applies to other exterior components as well.

John, it sounds like you need to avoid that car wash! I do get a drop or two on my windows when I wash it myself, but just a drop or two.

may need replacing as they just fatigue over time.
maybe $75 for the pair
takes like 5 minutes to r/r both
