Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure you have a clean workspace.

2. Inspect and Replace the Mirror Adjustment Switch

Tools Required: Screwdriver, trim removal tool.
Remove the trim panel surrounding the mirror adjustment switch.
Disconnect the electrical connector from the switch.
Inspect the switch for damage; if necessary, replace with a new switch.
Reconnect the electrical connector and reattach the trim panel.

3. Check and Replace the Fuse

Tools Required: Fuse puller or pliers.
Locate the fuse box (refer to the owner’s manual for the exact location).
Identify the fuse associated with the mirror adjustment (check the diagram on the fuse box cover).
Pull the fuse and inspect it; replace with the same amperage if it is blown.
Reassemble the fuse box cover and reconnect the battery.

4. Inspect the Wiring Harness

Tools Required: Wire strippers, electrical tape.
Trace the wiring from the adjustment switch to the mirror motors.
Check for any signs of wear, fraying, or corrosion.
Repair any damaged wires with electrical tape or replace as necessary.

5. Test the Mirror Motors

Tools Required: Jumper wires, multimeter.
Disconnect the mirror motor connector.
Use jumper wires to apply direct power to the mirror motor to test functionality.
If the motor does not operate, replace the mirror assembly.
