Removal Procedure

WARNING: This page is about a different car, the 2003 Pontiac Aztek and 2003 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

Important:  This sunroof system is timed from the factory in order to allow the actuator to shut off automatically when the sunroof window reaches a certain position. Use extreme care when removing the sunroof actuator from the sunroof module. Improper removal may cause the timing to be thrown off.

Anytime the sunroof actuator requires removal from the sunroof module, ensure that the sunroof window is in the fully closed position and the sunroof timing pins are installed.

  1. Position the sunroof window panel to the fully closed position.
  2. Remove the headliner. Refer to HEADLINER REPLACEMENT (AZTEK) or HEADLINER REPLACEMENT (RENDEZVOUS) .
  3. Remove the right and left front screw from the sunroof window panel. Refer to SUNROOF WINDOW REPLACEMENT  .

    Important:  Before removing the sunroof actuator, ensure that J 41718  are tight and holding the cable.

  4. Install J 41718  into the front sunroof window panel screw hole in order to retain the cable adjustment.
