Condition

Some customers may comment that the driver or passenger side door glass is inoperative, has a binding condition or a rattling noise.

Cause

This condition may be caused by the side door glass window regulator mounting bolts loosening.

Correction

Important
Do not replace the door window regulator.

Use the following procedure to correct the condition.

1. Remove the front side door trim panel on the affected side. Refer to Front Side Door Trim Panel Replacement in SI.
2. Remove the front side door water deflector. Refer to Front Side Door Water Deflector Replacement in SI.





3. Partially lower the side door glass on the affected door to relieve tension on the door glass regulator and to expose the bolts retaining the front door window to the window regulator.

Remove the bolts and nuts one at a time and apply GM Medium Strength Threadlocker, Part # 12345382 (in Canada 10953489), to the bolt threads as instructed in the product information. Reinstall the nut or bolt, but do not fully tighten the nut or bolt. Repeat the procedure to the remaining nuts and bolts one at a time.
