1.
Verify that the vehicle has the correct rear sunroof module support bracket on each side. See Figure 3 for bracket usage identification. If an
incorrect bracket(s) is verified, it must be replaced with the correct bracket(s) before proceeding.
2.
If the vehicle has the correct bracket on each side, verify that the rubber dust seal located on the "top" rear of the sunroof module is making "light"
contact with the inside of the roof sheet metal from side to side. See Figure 1. Contact of the seal to the roof can be viewed from the back seat. If
the seal is not making light contact on one or both sides, the rear support bracket(s) will need to be adjusted.
Rear Support Bracket Adjustment
1.
Measure the gap between the rubber dust seal and the roof sheet metal on the affected side(s).
2.
Remove the affected rear support bracket(s) from the vehicle and place in a vise.
3.
Carefully straighten the bracket(s) as necessary to eliminate the gap when reinstalled.
4.
Reinstall the bracket(s) to the roof. Tighten screws to 1 N.m (9 lb. in.).
5.
Raise and support the module so that it contacts the rear support brackets. Verify that the rubber dust seal is lightly contacting the roof.
6.
Loosely install the bolt that attaches the sunroof module to each rear support bracket.
