Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative terminal of the battery to ensure safety.
2. Inspect and Replace the Mirror Adjustment Switch
  • Remove the switch panel using a trim removal tool.
  • Disconnect the wiring harness from the back of the switch.
  • Test the switch with a multimeter to check for continuity.
  • If defective, replace with a new switch:
    • Connect the new switch to the wiring harness.
    • Reinstall the switch panel.
3. Check and Replace the Fuse
  • Locate the fuse box (typically under the dashboard or engine compartment).
  • Identify the fuse for the mirror adjustment (refer to the owner’s manual for the exact location).
  • Pull the fuse and inspect it for continuity.
  • If blown, replace it with a fuse of the same amperage.
4. Inspect and Repair Wiring
  • Remove the door panel to access the wiring harness if necessary.
  • Visually inspect the wires for fraying, corrosion, or breaks.
  • Repair or replace any damaged wiring using solder and heat shrink tubing or appropriate connectors.
5. Test the Mirror Motors
  • If the above steps do not resolve the issue, remove the mirror assembly.
  • Connect the mirror motor directly to a battery (use jumper wires) to test for functionality.
  • If the motor does not work, replace the mirror assembly.
