Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and a flat-head screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the fuse for the mirror adjustment (refer to the fuse diagram).
Check the fuse for continuity using a multimeter; replace if blown with an equivalent rated fuse.

3. Test the Adjustment Switch

Remove the switch panel using a flat-head screwdriver.
Disconnect the wiring connector from the switch.
Use a multimeter to check for continuity when pressing the adjustment buttons; replace the switch if faulty.

4. Check the Wiring Harness

Inspect the wiring harness connecting to the side mirrors.
Look for any visible signs of damage, such as fraying or corrosion.
Clean any corrosion with a contact cleaner and ensure connections are secure.

5. Test the Mirror Motor

If the wiring is intact, remove the mirror assembly from the door panel.
Connect the mirror motor directly to a power source to see if it functions.
If the motor does not operate, replace it with a new one.
