Sunroof Track Timing/Synchronization: Notes

WARNING: This page is about a different car, the 2008 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

This procedure requires that both the glass and the sunroof motor/actuator are set to the closed position. Individually, the glass must be mechanically aligned in the closed position as well as the motor/actuator is electronically timed in the closed position. Then the motor/actuator can be installed to the sunroof module.

Perform this procedure anytime:

A new sunroof motor/actuator is being installed.
The original sunroof motor/actuator is being re-installed.
