Solution

1. Preparation

Gather tools: multimeter, screwdrivers, socket set, and safety goggles.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Inspect Mirror Adjustment Switch

Remove the trim panel around the switch using a trim removal tool.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when pressing the switch.
If there is no continuity, replace the switch.

3. Check Fuses

Locate the vehicle's fuse box (typically under the dashboard or in the engine compartment).
Use a fuse puller to remove the fuse associated with the mirror adjustment system (refer to the owner's manual for specific fuse location).
Inspect the fuse for continuity; replace if blown.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the mirrors for frays, breaks, or corrosion.
Ensure all connectors are securely attached to the mirror motors and the switch.
Repair or replace any damaged wiring or connectors.

5. Test Mirror Motors

If the switch and fuses are functional, access the mirror motors by removing the mirror assembly (may require removing the door panel).
Connect the mirror motor directly to a power source to verify functionality.
If the motor does not operate, replace the mirror assembly.
