In Reply to: dry window seals posted by Steve Svalina on August 10, 1998 at 20:21:05:
: I'm experiencing sqeaky sounds from the passenger side windows over irregular road surfaces and upon accelerating from a stop. The "velvet"-like window seals feel very dry and give off a cracking sound when compressed. The sounds disappear when the windows are cracked slitely open. I've got an appointment next Monday with the local BMW dealer. Anyone have a similar problem? I already had the door seals replaced and corrected that problem.
in your second note you said it was an 1997 E39.
The fault is not the "window" seal but rather the seal that is along the top of each door. The noise is coming from the rubber strip that closes againt the body at the roof line - this is the rubber seal you can see from the outside with the door closed.
The noise is coming from slight movement of that rubber strip on the car body. This only seems to happen when the winhdow is closed tightly becasue the pressure of the window actually pushes the door frame up slightly, making the rubber strip contact the roof even more.
Solution - some slight rubber lubricant will keep the noise at bay for a few weeks. Also wax on the body at that point helps.
But the permanent solution is to replace those seals with the latest version - BMW apparently spent a lot of time determining what the best solution really was. New one has a "felt knap" like surface on the inside (next to the body).
These are apparently in short supply, and you may have to wait for them - ask to be "put on the waiting list".
