Removal Procedure

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.
    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 J 41718  are installed. See Special Tools .
  1. Position the sunroof window panel to the fully closed position.
  2. It is only necessary to lower the headliner. Only do those step in headliner replacement that will lower the headliner enough to gain access to the part. Refer to Headlining Trim Panel Replacement .
