A solution that i had is that if you can open your sunroof without it opening ur shade try that then fold the shade by pushing between or in the middle of it and popout the shade. this works but try not to push to hard or you can break the plastic runners on the side of the shade. check to see if nothing is in the way of the runners. then put back the back part first then slide it all the way to the back then, do the other part and clip them back together
(there might be a little metal piece that pushes your shades back so check that first to see if its there first)
can you explain this in better detail as this is a problem I have and I don't understand what you are trying to say...thank youcan you explain this in better detail as this is a problem I have and I don't understand what you are trying to say...thank you

Is there anything else to check before changing the motors ? Yeah , hook up a factory or some other type of professional scanner an check for DTC'S - diagnostic trouble codes,also to see if the scanner will communicate with the modules. Changing batterys without a alternate power supply can cause modules to go to sleep permanently.
Power Sunroof System Components
The Power Sunroof and Sunshade System consists of the following components:
• Sunroof control module
• Sunshade control module
• Sunroof switch
• Sunshade switch
• Rail and track assembly upon which the sunroof and sunshade glass rides
• S/ROOF/SUNSHADE Fuse 30 A
• Body control module (BCM)
Don't be a parts changer, learn how to diagnose! So before you go wasting your money on parts not needed see if a professional scanner can communicate with all the modules on the vehicle.
The Power Sunroof System will operate only with the ignition turned to the RUN or Accessory positions, this allows for retained accessory power (RAP) control of the sunroof and sunshade through the body control module (BCM). With the ignition in the run or accessory positions, the BCM supplies the sunroof and sunshade control modules with ignition voltage which allows sunroof and sunshade operation. Once the ignition switch is turned to OFF the sunroof will continue to operate until any door is opened or when the RAP timer reaches its shut-off limit. For a description and operation of the RAP operation, refer to Retained Accessory Power (RAP) Description and Operation.
Circuit/System Description
The sunroof and sunroof shade modules supply each of the switch signal circuits with a 12-volt reference. When a switch is pressed the signal circuit is pulled low signaling the sunroof or sunroof shade open or close request. The modules determine the motor direction based on inputs received from the sunroof switches. When the modules reverse the polarity of the applied voltage, the motors reverse direction. The sunroof shade module contains the logic for opening and closing the sunshade based on Serial Data from the sunroof control module. Ignition voltage is supplied to the sunroof and sunroof shade modules by the BCM. B+ is applied to the sunroof and sunroof shade modules via the S/ROOF fuse.
The sunroof shade module contains the logic for opening and closing the sunshade based on Serial Data from the sunroof control module. The sunroof shade module internally applies voltage and ground to the appropriate circuits of the reversible sunshade motor in order to move the sunshade panel to the open or closed positions.

Sunroof Description and Operation (One Connector System)
Sunroof
This diagnostic procedure is to be used for the 1 connector Sunroof System that combines the sunroof control module with the sunroof motor/actuator.
The Sunroof System consists of the following components:
• BATT MAIN 2 Fuse 50 A
• Body control module (BCM)
• RAP relay
• S/Roof Fuse 20 A
• Sunroof module (includes sunroof motor/actuator)
• Sunroof switch
The Sunroof System is controlled by the sunroof switch and the sunroof motor/actuator assembly.
When the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the body control module (BCM) applies a ground to the RAP relay in the instrument panel (I/P) fuse block. This activates the RAP relay and allows battery positive voltage to be applied through the SUNROOF Fuse to the sunroof module. Ground for the sunroof module is supplied from G302.
The sunroof can be placed in 3 preset positions:
• Open
• Vent
• Closed
When the sunroof switch is placed in the OPEN position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof motor/actuator then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the full open position.
When the sunroof switch is placed in the VENT position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof module then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the VENT position.
When the sunroof switch is placed and held in the CLOSED position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch close signal circuit. The sunroof module then applies voltage to the sunroof motor close control circuit and applies a ground to the sunroof motor open circuit. The sunroof motor then closes the sunroof.
The sunroof can be placed in any preferred open position when:
• The sunroof is in the fully opened position by pressing and holding the sunroof switch in the CLOSE position until the panel has reached the desired position then release the CLOSE switch in order to stop the sunroof
• The sunroof is opening, it can be stopped by momentarily pressing either side of the switch.
The sunroof control module, sun roof actuator, and the sunroof motor are integral parts of the sunroof module assembly and are not service separately.
Your best bet , take it to a qualified repair shop or buick dealer .
If your motor is audible and your fuses and connectors are okay, you may have to take a close look at the plastic gear parts up in the roof. The nylon parts do wear out since they are in the roof and more exposed to different temperatures. If any of that mechanism fails then your sunroof will stop working even if the motor is still good. It is a bit of a PITA to get to it since you will have to remove the headliner to get at the mechanism and then identify the worn part and replace it CAUTION: The sunroof system is timed from the factory so that the motor shuts off automatically when the sunroof window reaches a certain position. Extreme care must be taken when removing the motor, timing may be thrown off causing possible damage to the sunroof system. Anytime the motor is removed from the sunroof assembly the sunroof glass panel must be in the FULLY CLOSED POSITION or the unit will be out of timing. The drive motor cannot be reset to the park position after being removed.
CAUTION: The sunroof motor should only be powered through the vehicle battery and sunroof wire harness. Applying power to the sunroof motor leads will cause failure of the control module.
Move glass panel to the fully closed position.
Move glass panel to the fully closed position.

Remove the overhead console. (Refer to 8 - ELECTRICAL/OVERHEAD CONSOLE - REMOVAL)
Disconnect the control switch wire connector.
Remove headliner as necessary to gain access to sunroof drive motor. Refer to Headliner Removal and Installation for proper procedures.
Disconnect the drive motor wire harness connectors (Sunroof Drive Motor and Express Module).
Remove drive motor fasteners and remove motor from the sunroof housing
might try spraying white lithium grease on the slides and open and close few times my g6 did the same thing grease it and open and closed a few times then it work
you may have to strip out the roof lining to gain access to the sunroof component if you cant pull the sun visor free , dont keep pressing the power button as could at the least blow the fuse , at worst burn out the motor
Can't say for sure about this particular model, but most vehicles with sunroofs have a manual crank for situations like this. Generally it is located forward of the sunroof on the roof of the interior of the car, sometimes under a panel or interior light. This at least will get the roof closed until the problem can be fixed. It may also allow the sun roof to realign itself and help the electric crank to start working again.
