✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.
Typical repair cost: $60 – $400
Severity Level 1 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Power mirrors won't adjust — stuck in current position
- Power mirrors not working — no response when activated
- Mirror defrost/heater not working
- Infinite resistance in the power mirror circuit — broken wire or disconnected connector
Possible Causes
- Broken wire or connector pin in the power mirror system harness — common at flex points like door jambs or where wiring moves
- Disconnected or loose electrical connector — may have been bumped during other repairs
- Failed mirror motor — internal open circuit from age, heat cycling, or vibration
- Corrosion completely severing a wire or connector terminal — green crust on copper wiring
- Wiring harness damage from rodent chewing — look for nesting material near the engine or under dash
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 ($6-146 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, $74 diagnostic fee at shop)
- Trace the power mirror system wiring from connector to connector with a multimeter set to continuity/resistance mode — find and repair the break in the circuit ($86-243 labor for diagnosis and repair)
- Check and reseat all connectors in the power mirror system circuit — disconnect, inspect pins, clean with electrical contact cleaner, apply dielectric grease, and reconnect firmly ($12 DIY or $78 shop minimum)
- If mirror motor has failed internally (open circuit inside), replace it — don't try to repair sealed components ($50-400)
