Warnings

Tools required

Parts

• Front window regulator and motor assembly × 1 — Use OEM specification
• Door panel retaining clips (if damaged) × 1 — GM 11589292 or equivalent
• Vapor barrier (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V battery negative terminal and wait 2 minutes for system discharge
3. Roll window to full up position before disconnecting battery if motor is functional
4. Remove any items from door storage pockets
5. Ensure ambient temperature is above 60°F (15°C) for easier trim removal

Procedure

1. 1

   Remove door pull handle and switch panel
   Remove the screw behind the door pull handle using T20 Torx driver. Carefully pry out the power window switch panel from the front edge using a trim tool. Disconnect the electrical connector from the switch panel by pressing the release tab and pulling straight back. Set aside in a safe location.
2. 2

   Remove interior door panel fasteners
   Remove all T30 Torx screws securing the door panel (typically 2 along bottom edge, 1 in pull handle area, 1 behind speaker grille). Use trim removal tools to carefully release the retaining clips around the perimeter of the door panel. Start at the bottom rear corner and work around the panel, pulling outward gently to disengage clips.
3. 3

   Disconnect door handle cable and remove panel
   Lift the door panel upward to disengage from the window sill. Reach behind the panel and disconnect the interior door handle release cable by rotating the cable end 90 degrees and unhooking from the lever. Disconnect any remaining electrical connectors. Remove the door panel completely and set aside on a protected surface.
4. 4

   Peel back vapor barrier
   Carefully peel back the vapor barrier sheet to access the window regulator and motor. Only remove as much as necessary to access mounting bolts. If the barrier tears, it must be replaced or resealed with proper adhesive to maintain moisture protection.
5. 5

   Support window glass and disconnect from regulator
   Support the window glass in the full up position using masking tape across the top of the door frame or have an assistant hold it. Remove the two bolts securing the window glass to the regulator bracket through the access holes in the door frame. Carefully lift the glass slightly and secure it in the up position with tape to the door frame.
   ⚠Ensure glass is properly supported before removing attachment bolts to prevent glass from falling.

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door cavity. Press the connector lock tab and pull the connector straight off the motor. Note the routing of the wiring harness for reinstallation.
7. 7

   Remove regulator mounting bolts
   Remove all bolts securing the window regulator assembly to the door frame (typically 3-4 mounting bolts). Support the regulator assembly as you remove the final bolt. Carefully maneuver the regulator and motor assembly out through the large access opening in the door frame.

   Install new regulator and motor assembly
   Carefully maneuver the new window regulator and motor assembly into the door cavity through the access opening. Align the regulator mounting holes with the door frame mounting points. Install all mounting bolts hand-tight first, then torque to specification in a cross pattern to ensure even seating.

   Connect motor electrical connector
   Route the motor wiring harness in the same path as the original. Connect the electrical connector to the window motor, ensuring it clicks into place and the lock tab engages fully. Verify the connection is secure by gently tugging on the connector.
10. 10

    Attach window glass to regulator
    Remove the tape supporting the window glass. Lower the glass carefully until the mounting holes in the glass bracket align with the regulator attachment points. Install both mounting bolts and torque to specification. Ensure the glass is properly seated in the channels.

    Test window operation before final assembly
    Temporarily reconnect the 12V battery negative terminal. Reconnect the window switch panel and test the window operation through full up and down travel. Verify smooth operation with no binding or unusual noises. Check that the window seals properly at the top. Disconnect battery again before continuing.
12. 12

    Reinstall vapor barrier and door panel
    Press the vapor barrier back into place, ensuring complete adhesion around all edges. If damaged, install new barrier with appropriate adhesive. Reconnect the door handle cable and any electrical connectors. Position the door panel and engage it onto the window sill by pressing down. Press firmly around the perimeter to engage all retaining clips. Install all T30 Torx screws. Install the window switch panel and reconnect its connector. Install the door pull handle screw.

Reassembly

1. Verify all electrical connectors are fully seated and locked
2. Ensure vapor barrier is completely sealed to prevent water intrusion
3. Confirm all door panel clips are properly engaged before operating window
4. Reconnect 12V battery negative terminal and torque to 6.0 Nm per specification

Verification

• Test window operation through complete up and down cycles multiple times
• Verify window reaches full up position and seals properly against weatherstripping
• Check for smooth, quiet operation with no grinding or binding
• Confirm auto-up and auto-down functions work correctly (if equipped)
• Test window one-touch functions and anti-pinch safety feature
• Verify all door panel components are secure and properly aligned
• Check that door locks and interior handle operate normally
