Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver.
Disconnect the negative battery terminal to prevent electrical shorts while working.

2. Inspect Mirror Adjustment Switch

Remove the panel covering the mirror adjustment switch using a flathead screwdriver.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity in the switch. Replace if faulty.

3. Check Fuse

Locate the fuse box as per the owner's manual.
Identify the fuse for the mirror adjustment (refer to the diagram on the fuse box cover).
Remove the fuse and inspect it for damage. Replace with the same amperage if blown.

4. Inspect Electrical Connections

Remove the door panel to access the mirror assembly.
Examine the wiring harness connections leading to the mirror motors.
Clean any corroded connections and ensure all plugs are securely connected.

5. Test Mirror Motor

Disconnect the mirror from the wiring harness.
Using a multimeter, check the resistance of the mirror motor.
If resistance is outside specified range, replace the mirror assembly.

6. Reassemble Components

Reattach all wiring harnesses and components.
Reinstall the door panel and any covers removed during the process.
Reconnect the negative battery terminal.
