Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Clean the Adjustment Switch

Remove the switch panel using a trim removal tool.
Disconnect the wiring harness from the back of the switch.
Clean the switch contacts using electrical contact cleaner.
Reconnect and test the switch functionality before reassembling.

3. Check and Replace the Fuse

Locate the fuse box as per the owner's manual.
Identify the fuse responsible for the mirror adjustment (usually labeled).
Use a fuse puller to remove the fuse and inspect it for continuity.
Replace with a new fuse of the same amperage if blown.

4. Inspect Wiring and Connections

Remove the door panel to access the wiring harness for the mirrors.
Check for any frayed wires or poor connections, especially at the mirror motor connector.
Repair or replace any damaged wiring or connectors found during the inspection.

5. Test the Mirror Adjustment Motor

Disconnect the mirror motor connector.
Using a multimeter, verify the voltage at the connector while activating the adjustment switch.
If voltage is present but the motor does not operate, replace the mirror motor.
