Mirror Passenger Up/Down Motor Stalled
The passenger side mirror's up/down motor has stopped responding to commands, like a stuck elevator that won't move. The car's computer detected the motor isn't working within the expected time frame.
The ECU monitors the mirror motor's current draw and movement time during vertical adjustment commands. It expects the motor to respond within a specific timeframe (typically 1-3 seconds). If the motor stalls or doesn't complete the movement, the ECU logs a fault.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Motor Response Time | 1-3 seconds for full stroke | No movement or timeout exceeded |
| Motor Current Draw | 0.5-2.5 amps during operation | Stalled condition or excessive current |
Code B1669 is a low-severity fault. Your vehicle is generally safe to drive to a workshop for diagnosis. However, do not ignore it indefinitely — low-severity codes often indicate developing problems that become expensive if neglected. Book a diagnostic appointment within 2–4 weeks. If you notice any additional symptoms (rough running, power loss, unusual smells), treat it as higher priority.
Once the fault is repaired, B1669 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
