Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.
Tools Required: Screwdriver set, multimeter, trim removal tools.

2. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Use the fuse diagram to identify the correct fuse for the mirror adjustment system.
Remove the fuse and inspect it for damage; replace it if blown.
Reconnect the battery and test the mirror adjustment functionality.

3. Repair or Replace Wiring

If the wiring harness shows signs of damage or corrosion, proceed to repair or replace it.
Carefully remove the trim panel around the mirror adjuster to access the wiring.
Use a multimeter to check for continuity in the wiring.
Repair any damaged wires with solder and heat shrink tubing or replace sections as necessary.
Reassemble the trim panel and reconnect the battery to test.

4. Replace Mirror Adjustment Switch

If the switch is confirmed faulty, remove the trim panel surrounding the switch.
Disconnect the wiring harness from the back of the switch.
Replace the switch with a new OEM part.
Reassemble the trim panel and reconnect the battery to test.

5. Test Mirror Motors

If mirrors remain unresponsive, remove the mirror assembly from the vehicle.
Apply 12V power directly to the mirror motors to verify they are functional.
If the motors do not operate, replace the mirror assembly.
Reinstall the mirror assembly and reconnect all wiring.
