Warnings

Tools required

Parts

• Side mirror assembly × 1 — Use OEM specification
• Door panel clips (if broken) × 1 — GM part 11589292 or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery terminal and wait 2 minutes before proceeding
3. Roll down the window fully to prevent accidental electrical activation
4. Prepare workspace with clean towels to protect door panel during removal

Procedure

1. 1

   Remove door panel sail trim
   Using a trim panel removal tool or flathead screwdriver wrapped in cloth, carefully pry the triangular sail panel trim piece at the front upper corner of the door panel near the mirror base. This panel covers access to the mirror mounting bolts. Pull gently to release the retaining clips without breaking them.
2. 2

   Access mirror electrical connector
   Locate the electrical connector behind the sail trim panel. Press the release tab on the connector and pull straight back to disconnect the mirror wiring harness. For heated/power mirrors, ensure you fully depress the locking tab before pulling to avoid damaging the connector.
3. 3

   Remove mirror mounting bolts
   Locate the three 10mm mounting bolts securing the mirror assembly to the door frame. These are arranged in a triangular pattern. Use a 10mm socket and ratchet to remove all three bolts completely. Support the mirror from the outside while removing the final bolt to prevent it from falling.
   ⚠Have an assistant support the mirror from outside, or use tape to secure it while removing the last bolt
4. 4

   Remove mirror assembly
   Carefully pull the mirror assembly away from the door, guiding the wiring harness through the opening in the door frame. Ensure no wires are snagged or pinched. Set the old mirror aside in a safe location.
5. 5

   Prepare new mirror assembly
   Unpack the new mirror assembly and verify it matches the original configuration (power, heated, turn signal, etc.). Feed the wiring harness through the door frame opening from the outside, ensuring adequate slack for connection.
6. 6

   Position and align new mirror
   Align the new mirror assembly mounting holes with the threaded inserts in the door frame. Ensure the mirror base gasket is properly seated against the door to prevent water intrusion. Start all three mounting bolts by hand to ensure proper thread engagement before tightening.
7. 7

   Torque mirror mounting bolts
   Using a torque wrench and 10mm socket, tighten the three mirror mounting bolts to 42 Nm (31 lb-ft) in a star pattern to ensure even pressure distribution. Verify the mirror sits flush against the door with no gaps in the gasket seal.

   Module Mounting Bolts8 Nm (6 lb-ft)
8. 8

   Connect electrical harness
   Connect the mirror electrical harness by aligning the connector and pushing firmly until you hear and feel a positive click. Gently tug on the connection to verify it is fully seated and locked.
9. 9

   Reinstall sail trim panel
   Align the sail trim panel with its mounting location on the door. Press firmly on all clip locations until each clip fully engages with an audible snap. Verify the panel is flush and secure around all edges.
10. 10

    Reconnect battery and test
    Reconnect the negative battery terminal and torque to 6 Nm (4 lb-ft). Turn the ignition to the ON position (engine off) and test all mirror functions including power adjustment, heating element (if equipped), and turn signals (if equipped). Verify smooth operation in all directions.

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Verify all electrical functions operate correctly before closing vehicle
2. Check mirror stability by gently pushing on the mirror housing to ensure bolts are properly torqued
3. Inspect gasket seal around mirror base for proper sealing to prevent water leaks

Verification

• Test power mirror adjustment in all directions (up, down, left, right) from driver controls
• Verify heated mirror function activates when rear defrost is engaged (if equipped)
• Check that turn signal indicators flash properly in mirror housing (if equipped)
• Visually inspect mirror for proper alignment and secure mounting with no movement or rattles
• Confirm no gaps exist between mirror base and door surface that could allow water intrusion
