Installation Procedure

WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Align the splines on the sunroof motor/actuator shaft with the drive gear on the sunroof module assembly.
  2. Install the sunroof motor/actuator (2) to the mounting bracket, ensuring that the sunroof motor/actuator is fully seated.
    NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  3. Install the screws (1) that retain the sunroof motor/actuator (2) to the mounting bracket.

    Tighten 

    Tighten the sunroof motor/actuator screws to 3 N.m (27 lb in).
