Tools required

Parts

• Power mirror motor assembly × 1 — Use OEM specification
• Door panel clips (if damaged) × 5 — GM 11589292 or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect the 12V battery negative terminal and wait 2 minutes for system capacitors to discharge
3. Lower all windows to prevent accidental door lock engagement
4. Gather all necessary tools and replacement parts

Procedure

1. 1

   Remove door panel lower trim
   Using a panel removal tool, carefully pry out the lower door panel trim piece starting from the rear edge. Release the retaining clips by pulling outward gently. Set aside the trim piece.
2. 2

   Remove door panel fasteners
   Locate and remove all T20 Torx screws securing the door panel (typically 2-3 screws along the bottom edge and one behind the door handle). Keep screws organized for reinstallation.
3. 3

   Disconnect door panel electrical connectors
   Locate the window switch assembly connector and power lock switch connector. Press the release tabs and disconnect both connectors. If equipped with memory seats, disconnect the mirror memory connector as well.
4. 4

   Remove door panel
   Lift the door panel upward to disengage it from the window sill, then pull it away from the door frame. Carefully set the panel aside on a clean, padded surface to prevent scratches.
5. 5

   Remove water barrier access
   Peel back only the section of the water barrier film necessary to access the mirror mounting area (rear upper corner of door). Do not completely remove the barrier unless necessary. Use care to preserve the adhesive.
6. 6

   Disconnect mirror electrical connector
   Locate the mirror harness connector inside the door cavity. Press the release tab and disconnect the connector from the mirror motor assembly. Note the routing of the harness for reinstallation.
7. 7

   Remove exterior mirror assembly
   From inside the door, locate the three 10mm mounting bolts securing the mirror assembly to the door frame. Support the mirror from the outside with one hand while removing the bolts with the other to prevent the mirror from falling.
8. 8

   Separate mirror motor from housing
   With the mirror assembly removed, locate the screws or clips securing the motor assembly to the mirror housing. Carefully separate the motor from the housing, noting the orientation and position of any alignment tabs or gaskets.

    Reinstall mirror assembly to door
    Feed the electrical harness through the door opening and position the mirror assembly onto the door frame. Align the mounting holes and hand-start all three 10mm bolts before tightening to ensure proper alignment. Tighten bolts evenly in a cross pattern.
11. 11

    Reconnect electrical and test
    Reconnect the mirror electrical connector inside the door. Temporarily reconnect the 12V battery and test mirror operation in all directions (up, down, left, right) and fold function if equipped. Verify smooth operation before proceeding.

    Reseal water barrier and reinstall door panel
    Press the water barrier film back into place, ensuring a complete seal around all edges. Reinstall the door panel by reversing removal steps: reconnect all electrical connectors, align panel onto door frame, press firmly to engage clips, and reinstall all T20 Torx screws. Reinstall lower trim piece.

Reassembly

1. Ensure all door panel clips are fully seated before applying pressure
2. Verify all electrical connectors are fully engaged with audible clicks
3. Test window operation after door panel reinstallation to ensure no interference
4. Check door panel fitment gaps for uniformity around all edges

Verification

• Test mirror adjustment in all directions (up, down, left, right) from driver controls
• If equipped, verify mirror fold function operates smoothly
• Check for any unusual noises during mirror operation
• Verify mirror heater function if equipped (test in cold conditions or monitor with infrared thermometer)
• Confirm no rattles or loose components in door panel
• Inspect mirror housing exterior seal for proper weather sealing
