Common Symptoms
- Power mirrors won't adjust — stuck in current position
- Mirror defrost/heater not working
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the power mirror system
Possible Causes
- Faulty mirror motor — most common cause, test before replacing
- Damaged or corroded wiring/connector in the power mirror system circuit
- Blown fuse or faulty relay for the power mirror system
- Poor ground connection — check and clean all related ground points
- Control module fault — rare but possible, only consider after ruling out simpler causes
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 ($12-90 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, $111 diagnostic fee at shop)
- Inspect the wiring boot where it passes from the body into the door — this is the #1 failure point. Peel back the rubber boot and check for broken/cracked wires ($0 DIY inspection)
- Replace mirror motor if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($50-400)
- Check and replace any blown fuses in the power mirror system fuse circuit — if fuse blows again, there's still a short that needs to be found ($2-19 for fuses)
