✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.
Typical repair cost: $60 – $500

Common Symptoms
- Power mirrors not working or completely dead
- Power mirrors blowing fuses when activated
- Mirror defrost/heater not working
- Zero voltage on the power mirror system circuit — short pulls signal to ground
Possible Causes
- Chafed or pinched wire in the power mirror system circuit — wire insulation worn through, copper touching vehicle chassis/ground
- Failed mirror motor with internal short to ground — most common when the component gets wet or overheats
- Corrosion in the electrical connector allowing current to leak to the connector shell/ground
- Damaged wiring harness where it passes through a body panel grommet or near a sharp metal edge
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($29-97 at shop, free at auto parts store for basic scan)
- Visually inspect the power mirror system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $84 diagnostic fee at shop)
- Repair or replace damaged section of wiring harness where short is located — solder and heat-shrink all connections, don't use crimp connectors on critical circuits ($137-321 depending on accessibility)
- If mirror motor is internally shorted, replace with a quality OEM or OEM-equivalent aftermarket unit ($50-400)
- Clean all ground points related to the power mirror system — remove bolt, sand contact surface to bare metal, apply dielectric grease, and torque to spec ($79-120 at shop)
