Sunroof Motor/Actuator Initialization/Teach Process: Notes
WARNING: This page is about a different car, the 2016 Buick LaCrosse. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform the Initialization/Teach Process for both sunroof window and sunshade any time a new sunroof window or sunshade motor actuator is installed in the vehicle.
If the sunroof motor is new Initialize it first before doing the sunshade.
"Manual" indicates the first switch detent.
"Express" indicates the second switch detent.
- Ensure that the electrical harness on the headliner is connected to the sunroof motor.
- Put the ignition in the RUN position.
- Ensure that the sunroof window is in the fully closed position if relearning a used sunroof motor.
- Press the "Sunroof Manual Close Switch" and hold for more then 10 seconds. Do Not release the switch until the window finds the hard stop and moves sightly back.
- Open the sunroof with the sunroof switch in either the manual or express open position. Hold the switch until the sunroof is in the full open position and then release the switch.
- Press "Sunroof Manual Open Switch" and hold it for more then 10 seconds. DO NOT release the sunroof switch. At this time the sunroof window will automatically begin to move to the fully Closed position.
- Verify the operation of the sunroof window.
NOTE:
A slight clunk noise will be heard when this occurs. Rearward movement of sunroof is very slight and may not be noticed.
NOTE:
During this time it is necessary to keep the switch active until the process completes.
