Causes

  • Foreign object, debris or corrosion physically blocking mirror movement
  • Damaged or seized mirror actuator or gearbox
  • Faulty mirror position sensor (potentiometer) or switch stuck mechanically/electrically
  • Open/shorted wiring or corroded/loose connector between mirror and BCM
  • Blown fuse or failed relay in mirror power circuit
  • Software calibration fault or BCM/mirror module internal fault

Symptoms

  • Exterior mirror will not fold or unfold or moves only partially
  • Mirror adjustment not responsive, moves only in one direction or is stuck
  • Warning message or lamp regarding mirror fault on the instrument cluster
  • Intermittent or no mirror position feedback
  • Unusual motor noise or grinding from mirror housing
  • Blown fuse related to mirror circuit

What to check

  • Read and record B2336 and any other stored DTCs and module freeze-frame data with a diagnostic scanner
  • Attempt to reproduce the fault (operate mirror fold and adjustment functions) and note behavior
  • Visually inspect mirror housing for foreign objects, impact damage, water ingress, and corrosion
  • Check relevant fuses and relays for continuity and correct rating
  • Inspect connectors and wiring from mirror to door and to the BCM for corrosion, damage or loose pins
  • Operate the mirror switch and observe connector voltage/ground and any CAN/BUS messages if available

Signal parameters

  • Battery supply: approx. 12 V present at mirror power feed when mirror operation commanded
  • Ground continuity: low resistance between mirror ground and vehicle chassis (near 0 Ω)
  • Control signal: switched 12 V or PWM from BCM; frequency often tens to hundreds of Hz for some actuators
  • Actuator motor: low DC resistance (typically a few ohms) when measured across motor terminals; current draw rises when stalled
  • Position sensor (if fitted): varying resistance or voltage between low kΩ and high kΩ range depending on design
  • CAN/BUS: mirror module should send/receive position/command messages on body network (if equipped)

Diagnostic algorithm

  1. Connect a diagnostic scanner, read and record fault code(s) and any freeze frame/live data related to the mirror circuit.
  2. Clear the code and attempt to reproduce the fault to confirm it returns; note exact conditions when it sets.
  3. Visually inspect the mirror for physical damage, foreign objects, ice or corrosion preventing movement.
  4. Check fuses and relays for the mirror circuit; replace any blown fuses and retest.
  5. Operate the mirror switch while probing the mirror connector: verify battery voltage at the feed, good ground, and presence of the control signal when commanded.
  6. Measure actuator motor resistance and, if safe, measure current draw during commanded movement. High current or no movement indicates seized motor/gear or short.
  7. Inspect and test the mirror adjustment switch/joystick for stuck contacts or intermittent behavior; check continuity while operating.
  8. If the actuator appears seized, attempt gentle manual movement (per manufacturer procedure) to free or confirm mechanical failure; if free, retest electrical operation.
  9. Remove mirror trim and inspect internal harness, connector pins, and the position sensor (if fitted) for corrosion or damage; repair/clean connectors as required.
  10. If wiring and switch test good but the fault persists, replace the mirror actuator/module or the mirror assembly. After repair, clear codes and perform any required mirror/BCM calibrations or software updates.
  11. If replacement does not clear the fault, inspect body control module operation and CAN/BUS communications; consider module diagnostics or software reflash per manufacturer guidance.

Likely causes

  • Mechanical obstruction or seized actuator
  • Stuck or failed mirror switch/joystick
  • Damaged wiring or poor connector ground
  • Failed mirror position sensor inside actuator

Fault status

⚠️ Status
Mirror key stuck — mirror adjustment/fold input or position reporting stuck or out-of-range; possible mechanical obstruction, actuator or switch fault.
