2008 Buick LaCrosse Sunroof Motor

First Install the sunroof actuator screw to the sunroof module and the sunroof actuator bolts, and next connect the electrical connector to the sunroof actuator. Remove the pins and install the screws to the glass panel. Perform the Initialization/Teach Procedure and Inspect for proper operation of the sunroof. Lastly, install the headliner.

Start with positioning the sunroof window panel to the fully closed position. Lower the headliner enough to access the right and left window panel screws. Install the sunroof timing pins into the front sunroof window panel screw holes to retain the cable adjustment. Disconnect the electrical connector from the actuator and remove the sunroof actuator from the sunroof module.
