Causes

Seized or failed mirror adjuster motor/actuator
Stripped or damaged gearbox gears or linkage inside mirror housing
Foreign object, ice, corrosion or mechanical obstruction in mirror housing
Open/short in wiring harness or damaged connector pins
Faulty mirror control switch or body control module (BCM)/mirror control module
Blown fuse or faulty relay supplying mirror circuit

Symptoms

Passenger exterior mirror does not move when adjusted
Grinding, clicking or no sound from mirror when operating switch
Mirror stuck in one position and cannot be retracted or folded
Steady or intermittent DTC present for mirror circuit
Possible burning smell or high current draw if motor is stalled
Warning or message on instrument panel (manufacturer dependent)

What to check

Visually inspect passenger mirror housing for damage, ice, debris or foreign objects
Operate mirror while listening for motor noise and observing movement
Scan vehicle for stored DTCs and note related body/BCM codes
Check mirror fuse(s) and any related relays
Inspect wiring and connector for corrosion, water intrusion, broken wires, or bent pins
Measure supply voltage at mirror connector while operating switch (expect ~11–14 V)

Signal parameters

Mirror supply voltage when commanded: approx. 11–14 V (vehicle battery voltage)
Motor stall/activation current: can spike; typical small mirror motors may draw 1–10 A peak — consult vehicle-specific data
At-rest supply current: near 0 A when idle
Position sensor or feedback signal (if fitted): variable voltage or resistance dependent on design — typically 0–5 V or specific resistance values
CAN/vehicle network: mirror command messages present on CAN when switch operated (if applicable)

Diagnostic algorithm

Confirm complaint: attempt operation and reproduce symptom; note noises and exact behavior.
Read and record all related DTCs with a diagnostic scan tool (BCM/body module).
Visually inspect mirror assembly, remove debris/ice and check for obvious mechanical damage.
Check fuses and relays for the mirror circuit; replace if blown.
With key on, operate mirror and measure voltage at the mirror motor connector. No voltage: trace back to switch/BCM, check wiring continuity and ground.
If voltage is present but mirror does not move, measure current. High current or stall indicates mechanical bind or seized motor/gearbox.
Disconnect mirror connector and bench-test motor by applying 12 V directly (brief pulses, correct polarity). If motor runs, problem is wiring/connector/controls; if not, remove mirror and inspect gearbox and motor.
Inspect and, if necessary, disassemble mirror housing to check gears, linkages and motor mounting; replace damaged components.
Repair/replace wiring, connector or switch as needed; ensure corrosion is cleaned and contacts protected.
After repairs, clear DTCs, perform any required mirror calibration/learn procedure with diagnostic tool and retest operation.
Safety note: support mirror assembly during testing/repair and avoid forcing damaged plastic components.

Likely causes

Actuator motor seized or gearbox stripped (most common)
Wiring break or poor ground at mirror connector
Connector corrosion/wet connector preventing power to motor
Control switch failure or BCM not commanding mirror
Obstruction (ice/debris) physically preventing movement

Fault status

⚠️ Status

Passenger exterior mirror actuator/circuit fault detected — mirror not moving or movement obstructed. Service required to inspect motor, gearbox, wiring or control.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.0 hours
