Reason for change

Reason for block
Complaint:
Side windows can cause noise and/or reverse when closing.
Cause:
1. Interior dust shield seal: Faulty anti-friction coating can lead to increased friction and folding down of the sealing

lips.

Consequence: Friction is too large and results in noise and reversing windows.

2. Window guide rails (see Picture 1): Side window (2) can slip behind base lip (3) whereupon the base lip (3) folds

over (red arrow).

Consequence: Window runs on bare rubber and the friction is too large, which causes noise and reversing windows.

Remedy:
1. Visual inspection of upper (Picture 3, Item 2) and lower sealing lips (Picture 3, Item 1) of interior dust shield seals:

- If the sealing lip has folded down replace the affected interior dust shield seal.

2. Visual inspection of window guide rails at front and rear as to whether the base lip has folded down (see Picture 2):

- Open window and close slightly again.

- Use a plastic wedge to force the window guide rail above the window until the base lip (1) is visible.

- If the base lip is folded down replace the affected window guide rails.

IMPORTANT: When installing the side window make sure that the base lip (3) is not positioned at the side of the window
