Causes

  • Broken or chafed wiring in the door harness (common at door hinge/bellows)
  • Corroded or loose multi-pin connector at door module or motor
  • Failed window motor (internal short/open or excessive wear)
  • Failing door control module / window motor driver transistor(s)
  • Water ingress or contamination in door module or motor connector
  • Blown fuse or faulty relay in the accessory/window circuit

Symptoms

  • Window in affected door does not operate or operates intermittently
  • Slow or labored window movement, or window stops part-way
  • Fuse(s) for window circuit may blow when operating the window
  • Stored B2360 DTC and possibly related body/door module codes
  • No voltage or incorrect voltage present at the motor connector when switch is operated
  • Customer complaint of unusual noise from door area when attempting window operation

What to check

  • Use a diagnostic scanner to read DTCs and live data from the door module; note freeze-frame and accompanying codes
  • Visually inspect wiring and connectors at the door hinge (flex area) and motor connector for damage, corrosion or water
  • Check fuses and any related relays for the window circuit
  • Operate the window while monitoring voltage at the motor connector with the door switch commanded (observe both polarities when moving up/down)
  • Check continuity of wiring between door module and motor and between body harness and door module (with connectors disconnected)
  • Measure motor resistance with the connector disconnected (motor not energized)

Signal parameters

  • Commanded driver output: 0–12 V DC (polarity reverses for up/down) when switch is pressed
  • Expected motor resistance (static): typically low — approximately 1–10 ohms (varies by motor design)
  • Typical running current: ~2–8 A during normal movement (stall current much higher, possibly 20–40 A) — values vary by vehicle and motor
  • Driver output may use PWM: frequency often ~100–300 Hz (varies by manufacturer)
  • No-voltage condition:
  • Short-to-ground/short-to-B+ condition: near battery voltage present at the wrong time or fuse blow

Diagnostic algorithm

  1. Connect a diagnostic scan tool; record B2360 and any other related codes and live data; note which door/module is affected
  2. Inspect door hinge/bellow harness and connectors for visible damage, pin corrosion or water ingress; repair any damaged insulation or pins
  3. Check fuses/relays for the window circuit; replace if blown and retest to see if fault recurs
  4. With ignition on, operate the window while monitoring voltage at the motor connector. If no voltage, check continuity from the door module output pin to the motor connector
  5. If voltage is present but motor does not run, disconnect the motor and bench-test the motor by applying fused 12 V directly to the motor terminals (observe polarity for direction). If motor fails to run or draws excessive current, replace motor
  6. If motor runs when directly powered but no module output, back-probe the door module output. If output is absent or abnormal (stuck, scavenged, or damaged), suspect door control module driver fault
  7. If the output is PWM, use an oscilloscope to confirm waveform and duty cycle when commanded; abnormal waveform suggests driver electronics issue
  8. Check for short-to-ground or short-to-B+ on the motor supply wires with an ohmmeter (power off). Repair wiring faults (splice, replace harness section, or repair connectors)
  9. After repairs, clear codes and perform functional test of window operation through full range multiple times and re-scan for stored codes

Likely causes

  • Wiring damage at the door hinge/bellow (most common)
  • Corroded/contaminated connector between door and body
  • Failed window motor (motor draws excessive current or is open)
  • Faulty driver output in door control module
  • Water ingress causing intermittent shorts

Fault status

⚠️ Status
Door window motor output circuit fault detected — output open/short/overcurrent or incorrect voltage on the door module drive circuit.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.0 - 3.0 hours
