Note! The illustrations in this service information are used for different model years and / or models. Some variation may occur. However, the essential information in the illustrations is always correct.
Important information
Cars made from week 6, 2003, have new glass clamp screws installed in the lift mechanism carriage, 2 per door.
It is recommended that the new glass clamp screws, P/N 867 6801, are installed on cars made before this.
This means that if the side window and/or the power window lift mechanism cassette must be replaced or if the side window is removed from the power window lift mechanism cassette, the screws must be replaced before starting adjustment. The new glass clamp screws increase the potential for adjusting the window as follows.
Changing glass clamp screws
When the side window is to be reused when replacing the glass clamp screws, complete the replacement of one screw at a time.
At the same time, secure the position of the window against the lift mechanism cassette for the power window during the replacement.
Adjusting side window
Raise the window lift mechanism fully.
Close the door carefully.
Ensure that the rear side windows are in the highest position.
Check the position of the front side window against the weatherstrip and the distance to the rear side window. Note any discrepancies.
Lower the window lift mechanism fully.
Mark out the position of the front side window in the carriages.
Raise the window lift mechanism 10 cm.
Slacken off the screws using the torx grip. Slacken off only so much that the window can be adjusted.
Note! Turn clockwise to slacken off the screws.
Adjust the window according to the marking made when checking the deviating position of the window.
Tighten the screws. Tighten to 9 Nm.
Note! Turn counter-clockwise to tighten the screws.
Caution! Ensure that the clearance of 1 mm between the lift mechanism and the carriage is maintained.
Raise the window lift mechanism fully.
Close the door carefully.
Check the position of the window.
Repeat the adjustment if the position is incorrect.
Adjust pressure against weatherstrip front side window
Check that the pressure of the window against the weatherstrip is the same across the entire top edge of the window.
Hint: Clamp a strip of paper between the weatherstrip and the window and pull to feel the pressure.
If the pressure is the same, go to point Final adjustment of front side window.
If the pressure is not the same, adjust using the lower adjustment screws.
If this is not sufficient, shim in the window as follows.
Shim adjustment of front side window
Slacken off the glass clamp screws for the carriages using the torx grip.
Note! The new glass clamp screws are slackened off by turning clockwise.
To reduce the pressure at the front edge of the side window (1), shim the front carriage over the glass clamp screw.
To increase the pressure at the front edge of the side window (2), shim the front carriage under the glass clamp screw.
To reduce the pressure at the rear edge of the side window (3), shim the rear carriage over the glass clamp screw.
To increase the pressure at the front edge of the side window (4), shim the rear carriage under the glass clamp screw.
Tighten the screws. Tighten to 9 Nm.
Note! The new glass clamp screws are tightened by turning counter-clockwise.
Caution! Ensure that the clearance of 1 mm between the lift mechanism and the carriage is maintained.
Close the door and check that the window applies even pressure against the weatherstrip.
Final adjustment of front side window
Fine adjust the contact pressure using the lower adjustment screws.
Hint: Turn counter-clockwise to increase the pressure against the weatherstrip.
Spray water on the upper part of the weatherstrip for the B-post.
Close the door to the first lock position.
The water bead that is formed must be a maximum of 10 mm long.
Check:
- the seal and adjust if necessary
- that the window reaches the uppermost position when the door is open.
