Important: The sunroof motor/actuator is timed at the factory. If there is battery voltage applied to a new motor, or if the motor is removed and the sunroof glass is moved to a different position, the pre-timed settings within the sunroof motor/actuator are lost.
A motor should not be installed into the sunroof until the following conditions are satisfied:- The sunroof window is in a full closed position. Refer to Sunroof Track Timing/Synchronization .
- Connect all electronic connections (sunroof control unit, motor, sunroof switch, body harness) without installing the motor into the sunroof track.
- Press up on the sunroof switch, override position, and hold until the motor stops motion. This is the pre-timed factory position.
- Install the pre-timed factory position motor into synchronized sunroof track. Refer to Sunroof Motor/Actuator Replacement .
- Verify operation at all positions.
