Sunroof / Moonroof Motor: Service and Repair
SUNROOF MOTOR/ACTUATOR REPLACEMENTREMOVAL PROCEDURE
NOTE: This sunroof system is timed from the factory so that the sunroof actuator automatically shuts off when the window panel reaches a certain position. Be careful not to disrupt this factory timing when removing the sunroof actuator from the sunroof module. Disrupting the factory timing may cause damage to the sunroof system. Close the window panel whenever you remove the sunroof actuator from the sunroof module assembly.
1. Remove the headliner as necessary.
2. Disconnect the wire harnesses from the express module (8).
3. Remove the tie wraps securing the wire harness to the drive and return tubes (5, 6).
4. If the sunroof glass panel is not fully closed complete the following steps.
4.1. Locate the allen head screw on the drive gear of the sunroof motor/actuator (1).
The allen head screw is accessible with the sunroof motor/actuator in place.
4.2. Remove the red retainer from the allen head screw using a small flat-blade tool, if equipped.
4.3. Turn the allen head screw until the sunroof glass panel is fully closed.
You may need to apply a significant amount of force to move the sunroof actuator with the allen wrench.
4.4. Relieve the pressure on the sunroof motor/actuator by backing off the allen screw approximately 15 degrees.
IMPORTANT: The sunroof motor/actuator cannot be reused if this procedure is followed.
5. Remove the sunroof motor/actuator bolts (2) from the sunroof motor/actuator.
6. Disconnect the wire harness from the connector (1) on the sunroof motor/actuator.
7. Remove the sunroof motor/actuator from the sunroof module.
INSTALLATION PROCEDURE
1. Verify that the original sunroof motor/actuator or the new sunroof motor/actuator is timed to the closed position by preforming the following steps.
1.1. The hole in the large timing gear (3), the notch in the disk (2) below the drive gear and the scribe mark (1) on the drive gear should all be in line with each other.
1.2. If the actuator is not timed to the closed position, connect the switch, headliner harness and express module to the sunroof motor/actuator and run the actuator to the closed position. Verify all timing marks are aligned.
IMPORTANT: Before you install a new sunroof motor/actuator or re-install the old actuator to the sunroof module, ensure that the actuator is timed to the closed position.
2. Connect the wire harness to connector (1) on the sunroof motor/actuator.
3. Position the sunroof motor/actuator to the sunroof module.
4. Install the sunroof actuator bolts (2) to the sunroof motor/actuator.
NOTE: Refer to Fastener Notice in Service Precautions.
Tighten
Tighten the sunroof motor/actuator bolts to 3 N.m (27 lb in).
5. Connect the wire harness connectors to the express module (8), and secure the wire harness to the drive tube and return tube (5, 6) with tie wraps.
6. Install the headliner as necessary.
