Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers, replacement fuse (check owner's manual for specification).
Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse for the power mirrors and remove it.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.
Reconnect the fuse box cover and reconnect the battery terminal.

3. Test the Power Mirror Switch

Tools Required: Multimeter.
Reconnect the battery terminal.
Access the power mirror switch by removing the trim panel if necessary.
Use a multimeter to test for voltage at the switch terminals when activated.
If no voltage is detected, replace the power mirror switch.

4. Check Mirror Motor Functionality

Tools Required: Wire connectors, jumper wires.
Disconnect the power mirror motors from the wiring harness.
Use jumper wires to connect the motor directly to the battery (positive to positive, negative to negative).
If the mirrors operate when powered directly, the issue may lie in the switch or wiring.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness for any signs of wear, fraying, or damage.
Ensure all connectors are firmly plugged in; reseat any loose connections.
Repair or replace damaged wires and connectors as needed.
