Solution
1. Preparation
  • Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flat-head screwdriver.
  • Ensure the vehicle is parked on a flat surface with the ignition off.
  • Disconnect the negative battery terminal for safety.
2. Inspect the Power Mirror Switch
  • Remove the trim panel surrounding the power mirror switch using the flat-head screwdriver.
  • Disconnect the wiring harness from the switch.
  • Test the switch for continuity using a multimeter; if faulty, replace it.
3. Check the Fuse
  • Locate the fuse box and identify the fuse for the power mirrors (refer to the owner’s manual for specific fuse location).
  • Remove the fuse using a fuse puller or pliers.
  • Inspect the fuse for continuity; replace it if blown.
4. Test Wiring and Connectors
  • Inspect the wiring harness that leads to the power mirrors for any visible damage or corrosion.
  • Use a multimeter to check for voltage at the connector when the switch is activated; if no voltage is present, trace back along the wiring to identify breaks or shorts.
5. Check Power Supply to Mirror Motors
  • Remove the mirror assembly from the door (refer to service manual for removal procedure).
  • Connect the multimeter to the mirror motor terminals while activating the switch to verify proper voltage is supplied.
  • If voltage is present but the mirror does not move, replace the mirror motor.
