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
- Connect a diagnostic scan tool; record B2360 and any other related codes and live data; note which door/module is affected
- Inspect door hinge/bellow harness and connectors for visible damage, pin corrosion or water ingress; repair any damaged insulation or pins
- Check fuses/relays for the window circuit; replace if blown and retest to see if fault recurs
- 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
- 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
- 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
- If the output is PWM, use an oscilloscope to confirm waveform and duty cycle when commanded; abnormal waveform suggests driver electronics issue
- 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)
- 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
