Look toward the back of the sunroof on inside, if there is a small circular piece of plastic or other slot like opening. Open it with proper tool, probably a screw driver. In there should be the part u will need to turn, with the proper tool usually sized to fit socket & ratchet, or Allen key, or star wrench. In order to close, or begin to close the sunroof manually. Usually u can get it started manually, then run it as u usually
would.

Check the RAP fuse in the rear fuse box , this fuse powers the sunroof control module ! Fuse Block - Rear , Left rear of the passenger compartment, under the rear seat .
The sunroof module contains the logic for the opening and the closing of the sunroof. The sunroof motor assembly contains the reversible DC drive motor, the gear train, and the limit switch.
The sunroof module determines the sunroof motor direction based on inputs received from the overhead console sunroof switches. When the ignition switch is in the ON position or when retained accessory power (RAP) is active, voltage is applied to the sunroof module via the RAP relay. For a description and operation of the RAP system, refer to Retained Accessory Power (RAP) Description and Operation in Retained Accessory Power. The sunroof module controls the sunroof motor direction by changing the polarity of the applied voltage. The sunroof module remembers the sunroof position whenever the ignition switch is turned to the OFF position. The limit switch is used as an input to the sunroof module to indicate that the glass is fully closed, or in the comfort stop positions. The limit switch is grounded when the sunroof glass is in the fully closed or comfort stop positions, otherwise it is open.
The SLIDE CLOSE mode is initiated by moving and holding the sunroof slide switch (ROOF) forward. This applies a ground provided from the sunroof limit switch low reference circuit to the sunroof switch close vent signal input of the sunroof module. The sunroof module controls voltage to the control circuits of the sunroof motor. The sunroof motor will run until the limit switch contacts are closed. The closing of the limit switch will apply the sunroof limit switch low reference circuit to the sunroof limit switch soft stop signal circuit to the sunroof module, indicating the flush closed position has been reached. As the sunroof is approaching the close position the sunroof glass will force the wind deflector downward.
You need to have a factory scan tool hooked up an have it checked for DTC'S in the sunroof control module ! a code reader will not do this , a code reader will only check the engine codes for OBD 2 .
Important: The following must be completed before using the symptom tables.

1. Perform Diagnostic System Check - Power Sunroof in order to verify that all of the following are true:
?€¢
No DTCs are set.



?€¢
The control modules can communicate via the serial data link.


2. Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation

your better off taking to the dealer !

check your power motor The factory sets these motors on an open and close timer.or,the track may have an obstruction in it. other than that,may be time to replace the power motor(Brushes worn down)

most likely they control mechanism is a bit stiff/dry , if the roof will move forward spray wd40 up each side runners etc go back and forwards a bit at a time ,this should lubricate the mechanism and hope fully save ypou having the roof stripped out to solve the problem

These limits are not adjustable.

If it is able to open fully, but only closes part way it probably just needs to be lubricated. White lithium grease will do the trick. Get it in a spray can with a tube that can be attached to the spray nozzle. There is a set of tracks for the glass and one for the sunshade.

Fully open the glass, then spray some into the track where you can see the roller in the track. Move the glass forward part way, then spray some into the track at the back end of the glass. Now work the glass back and forth, open and close to distribute the grease.

After a few times it should fully close. Once fully closed, open fully then close fully. It ought to work correctly now. This worked for my Lincoln MKX and also for a Ford ZX3 sunroof.

You might need to do the same for the sunshade track before the glass will operate properly.

Recommend to do this annually. It doesn't require as much when regularly maintained.

THE ELECTRIC DRIVE SYSTEM FOR POWER SUNROOF IS NOT ADJUSTABLE.DONT REMOVE THE SUNROOF MOTOR UNLESS THE SUNROOF IS COMPLETELY CLOSED.OTHERWISE A NEW MOTOR WILL HAVE TO BE INSTALLED AND TIMED WITH A TOOL THAT COMES WITH THE NEW MOTOR.THE GLASS PANEL CAN BE ADJUSTED.OPEN THE INTERIOR SUNSHADE ALL THE WAY BACK AND OPERATE THE SUNROOF UNTIL FULLY CLOSED.THERE ARE THREE GLASS MOUNTING SCREWS ON EACH SIDE OF THE SUNROOF OPENING.INSIDE THE VECHICLE LOOSEN THE SCREWS SET THE FRONT EDGE OF THE GLASS TO BE JUST 1MM BELOW THE SURFACE OF THE ROOF.ADJUST THE GLASS AT THE REAR EDGE TO BE JUST ABOVE 1MM THE ROOF AT THE REAR TIGHTEN THE SCREWS.

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

1. 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.
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).
