Warnings

Tools required

Parts

• Front power window motor assembly × 1 — Use OEM specification for driver or passenger side
• Door panel retaining clips × 1 — Replace any broken clips during removal
• Vapor barrier tape/adhesive × 1 — If vapor barrier is damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect battery negative terminal and wait 3 minutes for system discharge
3. Roll window to approximately mid-position if motor is functional; if not, manually position glass to access motor
4. Gather all tools and replacement parts in work area
5. Protect door sill and exterior paint with towels or blankets

Procedure

1. 1

   Remove door panel trim components
   Remove the front door pull handle cover by prying gently with trim tool from rear edge. Remove Phillips screw behind cover. Remove door speaker grille by prying up carefully with trim tool. Remove any Phillips screws securing the armrest assembly.
2. 2

   Disconnect door panel electrical connections
   Locate and disconnect all electrical connectors accessible from the door panel including power window switch, power mirror switch (if equipped), and door lock switch. Press connector release tabs and pull straight out. Note connector orientations for reassembly.
3. 3

   Remove door panel mounting fasteners
   Remove all Phillips screws securing the door panel perimeter, typically located at the bottom edge and rear edge of panel. Remove any additional mounting bolts from armrest area using 10mm socket. Keep all fasteners organized by location.
4. 4

   Detach and remove door panel
   Lift door panel upward and away from door frame to disengage upper retaining clips. Carefully pull panel away from door, working around any remaining connections. Set panel aside on protected surface with interior facing up to prevent scratches.
5. 5

   Remove or fold back vapor barrier
   Carefully peel back the plastic vapor barrier sheet from door frame to access window motor mounting area. Use caution to preserve barrier integrity and adhesive if possible. If barrier tears, mark location for repair with new adhesive tape during reassembly.
6. 6

   Secure window glass
   Position window glass in the upper half of door travel. Use masking tape to secure glass to door frame exterior, preventing glass from dropping into door cavity. Alternatively, have assistant hold glass in position during motor removal.
   ⚠Failure to secure glass may result in glass falling and breaking inside door cavity
7. 7

   Disconnect window regulator from glass
   Locate the window regulator arm attachment to the glass channel brackets. Remove mounting bolts securing regulator lift arms to window glass bracket using 10mm socket. Carefully separate regulator from glass while maintaining glass support.

    Reinstall vapor barrier and door panel
    Reposition vapor barrier and press firmly to reactivate adhesive. Apply new adhesive tape if original was damaged. Reconnect all door panel electrical connectors. Position door panel and engage upper clips first, then press firmly around perimeter to seat lower clips. Install all mounting screws and bolts.

Reassembly

1. Reinstall all door trim components including speaker grille, pull handle cover, and any decorative trim pieces in reverse order of removal
2. Ensure all electrical connectors are fully seated and locked before final testing
3. Verify all door panel clips are properly engaged with no gaps or loose sections
4. Reconnect battery negative terminal and torque to specification

Verification

• With ignition ON, operate window through full range of motion multiple times verifying smooth operation
• Test window auto-up and auto-down functions (if equipped) to confirm proper operation
• Verify window seals properly against weatherstrip at full up position with no gaps
• Check for any unusual noises, binding, or hesitation during window operation
• Verify all door panel switches and controls function properly
• Test window operation from both door switch and driver's master switch
• Confirm door panel is secure with no rattles or loose sections
