Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the vehicle is on a flat surface and secure.

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically found under the dashboard on the driver’s side.
Use the fuse puller to remove the fuse related to the power mirrors (refer to the owner's manual for the exact location).
Inspect the fuse for a broken filament; if blown, replace it with a fuse of the same amperage.

3. Test and Replace the Power Mirror Switch

Tools Required: Screwdriver set, multimeter
Remove the trim panel surrounding the mirror switch using a screwdriver.
Disconnect the mirror switch connector.
Use a multimeter to test for continuity across the switch terminals while pressing the switch.
If there is no continuity, replace the switch with a new one.

4. Check Wiring and Connections

Tools Required: Wire stripper, electrical tape, multimeter
Inspect the wiring harness connected to the mirror for any frayed wires or loose connections.
Repair any damaged wires using electrical tape or replace them if necessary.
Ensure the connections are secure and reconnect the wiring harness.

5. Inspect and Replace the Mirror Assembly (if necessary)

Tools Required: Socket set, trim removal tool
If the mirrors are physically damaged, remove the mirror assembly by unscrewing the mounting bolts.
Disconnect the electrical connector from the back of the mirror.
Install the new mirror by connecting the electrical connector and securing it with mounting bolts.
