#PIT4305B: The Sunroof Will Only Vent Or Only Slide Open - keywords control inoperative module motor roof switch timing - (Apr 18, 2007)
Subject: The Sunroof Will Only Vent Or Only Slide Open
Models: 2005-2007 Chevrolet Equinox
2006-2007 Pontiac Torrent
2005-2007 Saturn VUE
This PI was superseded to update models. Please discard PIT4305A.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
The sunroof will only go to the vent position or only slide open. This concern can happen if the sunroof control module and sunroof motor are not timed correctly.
Recommendation/Instructions:
To time the sunroof motor and control module, follow the instructions below.
Using the vehicle switches, move the sunroof glass panel as near to the closed position as possible.
Without removing any wiring connections, unbolt the motor from the sunroof beam. Note: Once the motor is removed, the sunroof mechanism will be free to move.
Remove the glass and manually push the right and left drive cable plate until the closed position is reached (Closed position = 46mm between rear of locator and front of drive cable plate). See picture below.

With the sunroof electronics still connected the sunroof wire harness, but disconnected from the sunroof beam, press and hold the closed button until the motor stops.
Release and again press the close button and verify that the motor and electronics think that the sunroof is in the closed position.
Bolt the retimed motor / electronics into the mechanically retimed sunroof.
Verify correct sunroof operation.
Note: It is very important to understand the sunroof switch operation. If the sunroof module and motor were not timed correctly, the sunroof switch may operate the glass differently then it was designed to. This switch will slide forward and rearward, and this switch can also be pulled down or pushed up. Below is the instruction on how the sunroof switch operates.
To express-open the sunroof glass panel and sunshade, press/slide the switch rearward and release it. To stop the sunroof before it is completely open, press/slide the switch rearward again.
To close the sunroof, press/slide forward and hold the switch until the sunroof stops, lifts and seals at the back of the sunroof glass. Press/slide forward on the switch again to make sure the sunroof is fully closed.
To put the sunroof in the vent position, pull down on the front of the switch. Push up on the front of the switch to close it.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Attention: Fixed Operations Manager and Technician
This bulletin is being revised to add a model. Please discard Corporate Bulletin Number 05-08-67-010 (Section 08 - Body & Accessories).
Condition
Some customers may comment that the sunroof will no longer respond to the control switch while in a vented, partially opened, or fully opened position.
Cause
A software issue with the sunroof control module may cause the sunroof control module to incorrectly indicate a "closed" position, which may result in no power to the sunroof motor.
Correction
Verify the customer concern. If a condition is present, replace the sunroof control module with a new sunroof control module, P/N 15847643. Refer to the Service Procedure in this bulletin.
Service Procedure
Verify the customer concern by opening and closing the sunroof.
If the sunroof will not open, check the power windows.
- If the power windows are also inoperative, check the fuse. If the fuse has opened, refer to Corporate Bulletin Number 05-08-64-004 to install 30A circuit breaker.
- If the power windows are fully functional, refer to "Power Sunroof Inoperative" diagnostics (SI Document ID# 1392967) in the Body section of the 2005 Chevrolet Equinox or Saturn VUE Service Manual.
If the sunroof will open (or is already open), but will not close, proceed to Step 2.
Replace the sunroof control module. Refer to "Sunroof Control Module Replacement" procedure in the Body section of the 2005 Chevrolet Equinox Service Manual (SI Document ID# 1196049) or Saturn VUE Service Manual (SI Document ID# 1710479).
