Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace the Power Mirror Switch

Tools Required: Screwdriver set, trim removal tool.
Remove the door panel covering the power mirror switch:
- Use a trim removal tool to gently pry off the panel.
- Unscrew any fasteners holding the panel in place.
Disconnect the power mirror switch connector.
If no visible damage is present, check for continuity using a multimeter.
If defective, replace with a new power mirror switch by reversing the removal steps.

3. Check and Replace the Fuse

Tools Required: Fuse puller or pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power mirrors using the fuse diagram (typically labeled).
Pull the fuse and inspect it for continuity. If blown, replace with a fuse of the same amperage.
Reinstall the fuse and reconnect the battery terminal.

4. Inspect Wiring and Connections

Tools Required: Wire stripper, electrical tape, multimeter.
Visually inspect the wiring harness leading to the mirrors for damage.
If any issues are found, repair the damaged wires using solder or wire connectors.
Ensure all connections are secure and re-tape any exposed wiring.

5. Test the Mirrors

Reconnect the negative battery terminal.
Test the power mirror operation using the switch to verify proper functionality.
