Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, Phillips screwdriver, and wire stripper.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace the Power Mirror Switch

Remove the switch panel using a flathead screwdriver to pry it gently and avoid damage.
Disconnect the wiring harness from the back of the power mirror switch.
Use a multimeter to test the switch: set it to continuity mode and press the switch; check for continuity at the appropriate terminals.
If the switch is faulty, replace it with a new one by connecting the harness and securing the switch back into the panel.

3. Check and Replace the Fuse

Locate the fuse box (usually found under the dashboard on the driver's side).
Identify the fuse for the power mirrors (refer to the diagram on the fuse box cover).
Pull the fuse using a fuse puller and inspect it; if it’s blown, replace it with a fuse of the same amperage (typically 10A or 15A).
Reinstall the fuse and check if the mirrors function.

4. Inspect Wiring and Connections

Remove the door panel to access the wiring harness for the mirrors (use a socket set and Phillips screwdriver).
Check for any loose or damaged wires; repair any broken connections with wire connectors or solder as necessary.
Ensure the wiring harness to the mirror is securely connected.

5. Test Mirror Motors

If all previous steps do not resolve the issue, remove the mirror from the door.
Apply 12V power directly to the mirror motor terminals using jumper wires to check for operation.
If the mirror motor does not operate, replace the mirror assembly.
