Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Use the fuse diagram to find the power mirror fuse.
Remove the fuse with a fuse puller and inspect it for continuity.
- Tools Required: Fuse puller, multimeter (if testing continuity).
Replace the fuse if it is blown with one of the same amperage.

3. Test and Replace Power Mirror Switch

Remove the trim panel around the mirror switch using a trim removal tool.
Disconnect the electrical connector from the back of the switch.
Use a multimeter to test for continuity across the switch terminals when pressed.
If no continuity is found, replace the switch with a new one.
- Tools Required: Trim removal tool, multimeter.
- Parts Required: New power mirror switch (if necessary).

4. Inspect Mirror Motors

If the switch is functional, remove the door panel to access the mirror assembly.
- Tools Required: Screwdriver set, trim removal tool.
Disconnect the electrical connector from the mirror motor.
Test the motor for voltage when the switch is pressed using a multimeter.
If there is voltage but the mirror does not move, replace the mirror assembly.
- Parts Required: New mirror assembly (if necessary).

5. Reassemble Components

Reattach the door panel and ensure all clips and screws are secure.
Reconnect any wiring harnesses that were disconnected during the process.
