Sunroof Motor/Actuator Initialization/Teach Process (New Motor)

WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

Perform the Initialization/Teach Process any time a new sunroof motor actuator is installed in the vehicle.

Ensure that the electrical harness on the headliner is connected to the sunroof.
Press the sunroof switch to the close position until the window stops at the front hard stop in the fully closed position, then moves slightly back to the soft stop position. Release the switch.
Verify the operation of the sunroof.

IMPORTANT: The Initialization/Teach Process is not complete if any of the following actions take place before the initialization cycle is done:

The sunroof switch is not held in the close position.
The ignition and/or battery power has been removed.
The glass panel has not reached the closed position.

The Initialization/Teach Process must be restarted if the procedure is not carried out completely.
