Condition
Some customers may comment that the Ultraview Sunroof reverses direction when auto closing. This may be accompanied by a squeak or moan noise or
a shuddering condition while the sunroof is moving.
Cause
This condition may be caused by high friction forces due to a lack of lubrication or dirt/grime inside the rear tracks for the front sunroof. A binding front
drive cable or track may also cause this condition.
Correction
Clean and lubricate the tracks following the procedure below.
Tip
The rear track cleaning and sunroof motor initialization and teach module processes can be viewed on the GM Training website under Service
Know-How/TECHAssists (U.S. dealers). The TECHAssist course number is 50250.23T1.
1.
Remove the moveable sunroof glass panel.
1.
Open the sunroof until the air deflector is in the full upright position.
2.
Carefully remove the front and rear sunroof-to-lift arm fasteners.
3.
With the help of an assistant, lift and remove the sunroof glass panel.
Important:
Once the front sunroof glass panel is removed, operate the sunroof motor to open and close the front drive system. Listen for chattering
or noisy front drive cables. If a condition is noted, replace the front track assembly and drive cable that is causing the noise. It may not
be necessary to replace both sides. Once the front drive system operates freely, move to the rear track system.
2.
Remove the front cam extensions for the rear tracks. You can now remove the rear track guides. Clean the white plastic guide shoes with brake
clean. You may notice small scratches in the plastic shoes this is normal and it's not necessary to replace the guide arms.
3.
Remove the four white plastic guide shoes from the rear track guides. Once the shoes are removed, install the softer durometer rubber guide caps,
P/N 25880591, in place of the original ones. Once all for rubber caps are installed, reinstall the white plastic guide shoes over the caps. The shoes
must be reinstalled to reduce friction forces.
Important:
If cracks are found in the plastic guide shoes, replaces all four shoes, P/N 25979460.
4.
Once the rear track guides are removed, place a clean shop towel where the guide was removed from the track. Using shop air pressure, start at the
rear of the track and blow out the tracks moving back to front. Once air has been used to clean the track, obtain a steel rod (a used antenna mast
works as well) and wrap with a shop towel/paper towel soaked with brake clean. Move the rod or mast with the towel through both rear tracks.
Continue until all debris and grease is removed.
