Window Motor Initialization - Rear

WARNING: Keep objects and body parts clear of the glass panel when carrying out the initialization procedure. During the initialization procedure, the glass panel closes with high force and cannot detect objects in its path. Failure to follow this instruction may result in serious personal injury.

NOTE: The rear window motor is in error mode when shipped and will be inoperative until initialized.

NOTE: This procedure must be carried out when repairs are performed on any part of the power rear window system including when: the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window glass module is installed, and any operation in which grease or lubricants are applied to the power rear window system.

NOTE: All power rear window components (window glass module, window regulator, window motor and glass runs) must be installed and tightened to specification before carrying out this procedure.

1. Open the driver door. The door must remain open through the entire procedure.

2. Insert the key into the ignition and cycle to the RUN position 5 times, ending in the RUN position.

3. NOTE: When performing this step, movement of the rear window may not be seen, but the rear window motor will be active.

Depress and hold the power rear window control switch in the down position for 3 seconds and then release.

4. NOTE: If the rear window does not operate when performing this step, repeat steps 1,2 and 3.

Depress and hold the power rear window control switch in the down position for 3 seconds after the rear window stalls in the full down position.
