Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is in a safe, well-lit area.
Disconnect the battery to prevent electrical shock.

2. Inspect and Clean the Mirror Adjustment Switch

Remove the switch panel using a trim removal tool.
Disconnect the electrical connector from the switch.
Clean the switch contacts with electrical cleaner.
Reconnect and test the switch's functionality.

3. Check and Replace the Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse for the mirror adjustment (refer to the owner’s manual for the specific fuse location).
Use a fuse puller to remove the fuse and inspect it for continuity.
Replace any blown fuse with a new one of the same amperage.

4. Inspect Wiring and Connections

Visually inspect the wiring harness leading to the mirrors for frays, cuts, or loose connections.
Tighten any loose connectors or replace damaged wiring as necessary.

5. Test Mirror Adjustment Motor

If the switch and wiring are functional, access the mirror adjustment motor.
Disconnect the motor's electrical connector.
Apply direct power from a 12V battery to the motor terminals to check if the motor operates.
If the motor does not function, it may need replacement.
