Sunroof Actuator Mounting Bracket Diagnostics

This section of the bulletin is intended to aid in sunroof actuator mounting bracket diagnostics. Refer to the service predictors in this bulletin for sunroof actuator mounting bracket diagnostics and replacement.

Sunroof Module Diagnostics

This section of the bulletin is intended to aid in sunroof module diagnostics. This information is in addition to the service information available in the appropriate S-Series service manual.

This section of the bulletin is intended to summarize the sunroof components that can be serviced by following the service procedures in this bulletin and in the S-Series service manual. Based on recent sunroof warranty information, it has been found that sunroof modules/sunshades have been replaced when they could have been serviced with a component.

The following sunroof components are serviceable:

Important: Sunroof glass seal is no longer serviceable

Important: Do not replace sunshade due to broken slide blocks. Replace slide blocks using sunshade kit.

1. Remove cable locator blocks.

1.1.	Open sunroof.

1.2.	Remove locator block fastening screws.

1.3.	Remove locator block using needle nose pliers.





Important: If guide channel is fractured/broken, the cable end will most likely be separated from the separated from the guide channel.

2. Lift sunroof drive cable from guide channel.
3. Inspect guide channel for damage.

•	If guide channel is broken or fractured, replace sunroof. Refer to the appropriate S-Series service manual for procedure.

•	If guide channel is not broken or fractured, proceed to step 4 and replace cable locator blocks. Then, refer to the Sunroof Module Diagnostics" chart in this bulletin for additional diagnostics.




4. Apply Permatex® medium strength threadlocker (or equivalent) to locator block fastening screws. Make sure to cover the last few threads.
5. Install locator blocks.
6. Install locator block fastening screws.

Tighten
Tighten the locator block fastening screws to 2 N·m (17.5 lb ft)

1. Remove sunroof from vehicle. (Refer to "Sunroof Module Assembly Removal" procedure in the appropriate S-Series service manual).



2. Place a straight edge across sunroof actuator mounting bracket as shown in illustration and inspect bracket for warpage.

•	If actuator mounting bracket is warped, proceed to step 3.

•	If actuator mounting bracket is not warped, refer to "Sunroof Actuator Mounting Bracket Diagnostics" chart in this bulletin for additional diagnostics.

Important: Prior to removing sunroof/sunroof actuator, make sure sunroof glass is in full closed position. this will result in proper actuator to module timing provided actuator is not operated after it is removed.

3. Remove sunroof actuator. (Refer to "Sunroof Actuator [Motor] Removal" procedure in the appropriate S-Series service manual).



4. Using a 3 mm (.012 in.) drill bit, remove rivet that holds sunroof actuator mounting bracket to module front beam.
5. Obtain tube assembly/actuator mounting bracket kit (P/N 21059928).




Important:  Make sure sunroof actuator mounting bracket stays tight against drive tube during rivet installation.

6. Place a new actuator mounting bracket over drive tubes, making sure insert (included with tube assembly/actuator mounting bracket kit [P/N 21059928] is mounted on bracket in correct position, and secure with replacement 3 mm 12.3 mm rivet.
7. Install sunroof actuator. (Refer to "Sunroof Actuator [Motor] Installation" procedure in the appropriate S-Series service manual).
8. Operate sunroof to insure repair has resolved customer complaint.

•	If repair has resolved complaint, proceed to step 9.

•	If repair has not resolved customer complaint, refer "Sunroof Actuator Mounting Bracket Diagnostics" chart in this bulletin for additional diagnostics.

9. Install sunroof. (Refer to "Sunroof Module Assembly Installations" procedure in the appropriate S-series service manual.)

To receive credit for this repair during the warranty period, submit a claim through the Saturn Dealer System for B2780 (Housing Assembly, Sunroof (Module) - Replace) or B2752 (Cap, Track Cover, Right - Replace) or B2753 (Cap, Track Cover, Left - Replace) or N3360 (Motor, Sunroof - Replace).
