Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and any replacement parts if needed.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Replace the Mirror Switch

Remove the door panel using a screwdriver and socket set to access the mirror switch.
Disconnect the wiring harness from the mirror switch.
Test the switch for continuity with a multimeter:
- Set the multimeter to continuity mode.
- Press the mirror adjustment switch and check for continuity across the terminals.
If the switch shows no continuity, replace it with a new one.
Reconnect the wiring harness and reattach the door panel.

3. Check and Replace the Fuse

Locate the fuse box and identify the fuse for the power mirrors (refer to the owner's manual for the exact location).
Pull the fuse out with a fuse puller or pliers and inspect it.
If the fuse is blown, replace it with a new fuse of the same amperage.
Reassemble any components removed and reconnect the negative battery terminal.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the mirrors for any signs of damage or wear.
Disconnect and clean any corroded connectors with electrical contact cleaner.
Reconnect any loose or corroded connections.

5. Test Mirror Operation

After performing repairs, reconnect the battery terminal.
Test the function of the power mirrors using the adjustment switch.
Confirm that all mirrors move as intended.
