Solution

1. Preparation

Gather tools: OBD-II scanner, screwdriver set, multimeter, trim removal tools.
Disconnect the vehicle's battery to avoid electrical shock or short circuits.

2. Access the Mirror Assembly

Use a trim removal tool to gently pry off the cover of the passenger side mirror.
Remove screws or clips securing the mirror assembly, using the screwdriver set.
Carefully detach the mirror assembly from the door.

3. Inspect and Test the Mirror Motor

Use a multimeter to check the voltage at the mirror motor connector while attempting to adjust the mirror.
- If there is no voltage, trace the wiring back to the control module for faults.
- If there is voltage, the motor may be faulty.
If necessary, apply 12V directly to the motor terminals to test its operation.

4. Replace the Mirror Motor (if applicable)

If the motor is confirmed to be faulty, remove it from the mirror assembly by unscrewing it.
Install the new mirror motor by reversing the removal steps.
Reconnect the wiring harness securely to avoid future issues.

5. Reassemble the Mirror

Reattach the mirror assembly to the door, ensuring all screws or clips are secured.
Snap the cover back into place, ensuring it is flush with the door panel.

6. Finalize the Repair

Reconnect the vehicle's battery.
Test the mirror adjustment controls to confirm functionality.
