Fixing Non-Adjustable Side Mirrors on a Chevrolet Silverado 1500 T1XX (2019-2023)
Tools Required
  • Multimeter
  • Wire stripper/crimper
  • Flathead screwdriver
  • Phillips screwdriver
  • Torx screwdriver set
  • Trim removal tools
  • Basic socket set
Repair Instructions

Step 1: Inspect and Replace the Fuse

  1. Locate the fuse box under the dashboard on the driver’s side.
  2. Use a fuse puller or pliers to remove the relevant fuse (check the owner’s manual for the specific fuse location).
  3. Inspect the fuse; if it appears blown (the wire inside is broken), replace it with a new fuse of the same amperage.

Step 2: Check the Adjustment Switch

  1. Remove the trim panel around the switch using trim removal tools.
  2. Disconnect the switch connector.
  3. Using a multimeter, check for continuity across the switch terminals when the switch is activated.
  4. If the switch is faulty, replace it with a new one.

Step 3: Inspect Wiring and Connectors

  1. Follow the wiring harness leading from the switch to the mirror motors.
  2. Check for any visible damage or corrosion.
  3. Repair any damaged wiring with wire strippers and crimp connectors.
  4. Ensure all connectors are firmly seated.

Step 4: Test Mirror Motors

  1. If power is present at the motor connector (using a multimeter), but the mirrors do not adjust, the motor may be faulty.
  2. To access the mirror motor:
    • Remove the door panel by unscrewing screws and gently prying it away from the door frame.
    • Disconnect the wiring harness from the mirror assembly.
  3. Test the motor by applying direct power from a 12V battery (ensure correct polarity) to see if it operates.
  4. If the motor does not function, replace the mirror assembly.

Step 5: Reassemble

  1. Once repairs are complete, reconnect all harnesses and screws.
  2. Reattach the door panel carefully, ensuring all clips are secured.
  3. Test the mirrors again using the adjustment switch.
Conclusion

Following these steps should help you diagnose and fix the issue with your side mirrors not adjusting on your Chevrolet Silverado 1500 T1XX. If all else fails, consider consulting a professional technician for further inspection.
