Date: May 20, 2009
Subject: Front Side Door Glass Loose in Channel, Wind Noise, Water Leak (Revise Window Regulator Mounting Hole)
Models:
2008-2010 Chevrolet Cobalt (Sedan Only)
2008-2010 Pontiac G5 (Sedan Only)
Condition
Some customers may comment that the left and/or right front side door glass may leave the rear of the front side door window weatherstrip run channel
when being cycled up or down. This may also lead to wind noise and water leak issues in the upper B-pillar area.
Cause
This condition may be caused by the window glass rocking forward in the door as the window is cycled. This may allow the glass to disengage from the
rear of the front side door window weatherstrip run channel. The rocking condition may be caused by the window regulator being improperly positioned
within the door.
Correction
Cycle the glass down, then up. If the glass disengages from the rear of the front side door window weatherstrip run channel when the window glass is
being lifted, proceed with the following repair steps. If the glass appears to be operating correctly, proceed with the established diagnostic and repair
procedures in SI to correct the condition.
Note
Do not replace the front side door window weatherstrip unless it is damaged.
1. Lower the door glass approximately 75 mm (3 in) on the affected door.
2. Remove the front side door trim panel. Refer to Front Side Door Trim Panel Replacement in SI.
3. Remove the two bolts retaining the arm rest bracket and remove the bracket.
4. Partially remove the front side door water deflector in order to gain access to the rear regulator mounting bolt area.
