How do I reprogram the sunroof shade? It only closes half way.

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.

from @fredboy20:
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)

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

Cheak out the channels line there glass runing one moter woking proper and othe is not working so please see the motorized scheduled root with diagram

there is a part of the shade jammed in the track if you remove the piece is jammed it will work properly

make it go back to the open position,look down the side of the tracks in the roof that the sun shade slides in and you will probable find the guides for the sunshade are jamming up the tracks. only way to replace them<4 one in each corner> is to remove the glass section and then close sunshade that will give access to the 4 guides which are available from dealer as a kit
