NOTE:
This bulletin applies to vehicles equipped with a Power Moonroof (sales code GWA).
SYMPTOM/CONDITION:
A pop/thump sound coming from the Moonroof when cycling from the "Closed" to the "Open" position.
DIAGNOSIS:
If the vehicle operator describes the Symptom/Condition, perform the Repair Procedure.
PARTS REQUIRED:
REPAIR PROCEDURE:
1. Open the Moonroof to the 'Vent" position.
2. Clean the exposed Moonroof seal bulb with an alcohol prep pad.
NOTE:
Allow the alcohol to dry before proceeding.
3. Start applying the lubricant, using the applicator, in the center of the rear Moonroof seal bulb and working outward. Continue the application around the corner and work forward along the seal bulb (Fig. 1) and (Fig. 2).
NOTE:
Slower is better. A good application will have the appearance of being wet.
4. Continue forward with the applicator until contact with the seal bulb can no longer be made (Fig. 3).
5. Repeat Step # 3 and Step # 4 on the other side of the glass panel.
6. After coating both sides and the rear, allow the lubricant to dry for at least 3 minutes.
7. Cycle the glass panel open by:
a. Press and hold the "Open" button on the switch until the Moonroof is approximately half open.
8. Clean as much of the seal bulb as possible with an alcohol prep pad.
NOTE:
Allow the alcohol to dry before proceeding.
9. Start applying the lubricant, using the applicator, in the center of the front Moonroof seal bulb and working outward. Continue the application around the corner and work rearward along the seal bulb (Fig. 4).
NOTE:
Turning the applicator around can aid in getting the coating as far into the corner as possible (Fig. 5).
NOTE:
This area is important because it has been determined that from both front corners to about 3 inches inboard is where most of the sound originates.
10. Repeat Step # 8 and Step # 9 on the other side of the glass panel.
11. Allow the lubricant to dry for at least 3 minutes.
12. Close the Moonroof.
