Complaint
Excessive resistance of door side windows when being raised/lowered, cracking and squeaking noises.
Cause
Sealing lip of inner sealing rail (see picture 1 and picture 2, pos. 40 and 130) folds down while side windows are being
lowered (opened).
When the side windows are raised (closed), the sealing lip is pulled back up again.
Remedy
Replace inner sealing rail.
Then perform normalization of the window lifter system in the relevant door control unit.
