Tools required

Parts

• Rear power window motor assembly × 1 — Use OEM specification
• Door panel trim clips (if damaged) × 1 — GM 11589292 or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect the 12V auxiliary battery negative terminal located in the rear cargo area
3. Wait 2 minutes for electrical systems to power down completely
4. Roll the rear window to the full up position before beginning disassembly
5. Protect door exterior with a fender cover or towel to prevent scratches

Procedure

1. 1

   Remove rear door panel
   Remove the screw cover behind the interior door handle. Remove the T30 Torx screw securing the door handle trim. Use trim panel removal tools to carefully release the door panel retaining clips starting from the bottom edge and working upward. Lift the panel up and away from the door frame once all clips are released.
2. 2

   Remove vapor barrier access
   Peel back the plastic vapor barrier only in the area necessary to access the window motor. The motor is located in the lower rear section of the door. Secure the barrier with masking tape to prevent it from falling back into position during work.
3. 3

   Support window glass
   With the window in the full up position, secure the glass using masking tape from the glass to the door frame, or have an assistant hold the glass. This prevents the window from dropping when the motor is disconnected from the regulator.
4. 4

   Disconnect window motor electrical connector
   Locate the electrical connector on the window motor. Press the locking tab and carefully disconnect the wiring harness from the motor. Note the connector orientation and any wire routing clips for reassembly.
5. 5

   Disconnect motor from regulator
   Locate the connection point between the motor gear and the window regulator mechanism. Remove the fasteners securing the motor to the regulator assembly. On this model, the motor is typically secured with three bolts to the regulator plate.

    Reconnect electrical connector
    Connect the wiring harness to the window motor, ensuring the connector locks securely. Route the harness through any retention clips to match the original configuration.
11. 11

    Test window operation
    Reconnect the 12V battery. Before reinstalling the door panel, test the window operation through several full up and down cycles. Verify smooth operation without binding, unusual noise, or hesitation. Remove the temporary glass support if used.

    Reinstall vapor barrier and door panel
    Reposition the vapor barrier, ensuring it is properly sealed around all edges. Align the door panel with the mounting clips and press firmly to seat all clips. Reinstall the door handle trim screw and replace the screw cover.

Reassembly

1. Ensure all electrical connectors are fully seated and locked before final panel installation
2. Replace any damaged door panel clips with new clips to ensure secure panel retention
3. Verify the vapor barrier is properly sealed to maintain door weatherproofing

Verification

• Test window operation through multiple complete up and down cycles, verifying smooth movement
• Check that the window auto-up and auto-down features work correctly if equipped
• Verify the window seals properly against the weatherstrip at the top of the door frame
• Inspect door panel for secure fit with no gaps or loose clips
• Confirm no unusual motor noise during operation
