Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety during repair.
2. Inspect and Replace the Power Mirror Switch
  • Tools Required: Screwdriver set, trim removal tool
  • Remove the door panel to access the power mirror switch.
  • Disconnect the wiring harness from the switch.
  • Using a multimeter, test for continuity on the switch. Replace if faulty.
  • Reconnect the new switch to the harness and reassemble the door panel.
3. Check and Replace Blown Fuses
  • Tools Required: Fuse puller or needle-nose pliers
  • Locate the fuse box, usually found under the dashboard or in the engine compartment.
  • Identify the fuse associated with the power mirrors (refer to the owner’s manual).
  • Pull the fuse out and inspect it for continuity. Replace if blown with the same amperage rating.
4. Repair or Replace Damaged Wiring
  • Tools Required: Wire stripper/crimper, electrical tape
  • Inspect the wiring harness connected to the mirrors and the switch for damage.
  • If damage is found, use wire strippers to remove the insulation and crimp new connectors or splice in new wire.
  • Wrap repaired sections with electrical tape to prevent future exposure.
5. Test Mirror Motors
  • Tools Required: Power source (like a 12V battery), wires
  • Disconnect the mirror motors from the wiring harness.
  • Apply a direct 12V power source to the motor terminals to test their functionality.
  • If the mirrors operate correctly, the issue lies within the switch or wiring; if not, replace the mirror motors.
