Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box: Check the owner’s manual for the exact location.
Remove the cover and identify the fuse for the power mirrors (refer to the fuse diagram).
Pull the fuse using a fuse puller and inspect it. If blown, replace it with a fuse of the same amperage (usually 10A or 15A).
Reinstall the fuse box cover.

3. Replace the Mirror Control Switch (if faulty)

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the wiring harness connected to the mirror control switch.
Install the new mirror control switch by connecting the wiring harness and securing it in place.
Reassemble the door panel.

4. Repair or Replace Wiring Harness (if damaged)

Inspect the wiring harness visually; look for frayed wires or loose connections.
If damage is found, repair the wires using electrical tape or heat shrink tubing.
If the damage is extensive, replace the entire wiring harness with a new one.

5. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Test the mirror adjustment controls to ensure proper function.
