Solution
1. Preparation
  • Gather required tools and parts.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
  • Disconnect the battery to prevent any electrical shorts.
2. Check and Replace Fuses
  • Locate the fuse box (typically under the dashboard or in the engine compartment).
  • Remove the fuse for the side mirrors using a fuse puller.
  • Inspect the fuse; replace it if it is blown with a new fuse of the same amperage.
3. Inspect and Replace the Mirror Adjustment Switch
  • Remove the door panel to access the mirror adjustment switch.
    • Use a trim removal tool to gently pry off any clips.
    • Unscrew any screws securing the panel.
  • Disconnect the wiring harness from the mirror adjustment switch.

  • Install the new switch by connecting the wiring harness and securing it in place.
4. Check Wiring and Connectors
  • Inspect the wiring harness leading to the mirrors for any signs of wear, fraying, or corrosion.
  • If damage is found, repair or replace the affected wiring.
  • Make sure all connectors are securely attached and free from corrosion.
