Driver-side electric window motor short to ground

100%
Causes
- Internal short inside the driver-side window motor (armature or wiring)
- Damaged wiring harness with conductor contacting chassis ground (pinch, chafe, or broken insulation)
- Corroded or water-damaged connector causing low-resistance path to ground
- Faulty window switch or shorted switch harness
- Shorted output in the body or window control module (rare)
Symptoms
- Driver window inoperative or only moves intermittently
- Blown fuse for power windows or repeated fuse failure
- Burnt smell or heat from the door area near the motor
- DTC B1413 stored in body/control module
- Switch shows no response or abnormal behavior from driver window circuit
What to check
- Read and record all stored DTCs and freeze/frame data with a diagnostic scanner
- Visually inspect driver door wiring harness, grommet/boot and connectors for damage, corrosion or water ingress
- Check fuses and relays for the power window circuit
- Back-probe motor and switch connector pins to confirm supply and ground states with ignition and switch operated
- Measure resistance/continuity between motor feed and chassis ground with connector disconnected
- Measure motor current draw with ammeter when directly powering the motor (bench test) if safe to do so
Signal parameters
- Battery voltage at motor feed pin (V) with ignition/accessory on and switch operated
- Resistance from motor feed to chassis ground (Ω) with connector disconnected
- Motor coil resistance between motor terminals (Ω)
- Current draw when motor is powered (A) — normal running vs stalled
- Connector pin voltages when switch is operated (V)
- CAN/diagnostic body module output status (if available)
Diagnostic algorithm
- Connect a scan tool, read and note all codes and any related body module messages. Do not replace parts yet.
- Visually inspect the driver door harness, rubber boot and connectors for chafes, broken wires, corrosion, or signs of overheating.
- Verify fuses and relays in the power window circuit; replace a blown fuse only after determining cause.
- With ignition on, back-probe the motor connector. With the switch operated, check for expected voltage on the feed pin. If feed is shorted to ground, voltage will be near 0 V.
- Disconnect the motor connector. Measure resistance between the motor feed pin and chassis ground. Low resistance indicates a short inside the motor or at the connector.
- Measure motor coil resistance between motor terminals. Very low resistance or near short indicates internal motor fault.
- If motor tests normal, inspect continuity from the module/switch feed pin back through the wiring to the control module for a short to ground (use wiring diagrams). Wiggle test the harness at the door hinge while observing for intermittent shorts.
- If a short is traced to a connector or harness section, repair or replace the damaged wiring/connector. Protect repairs from flexing and moisture.
- If wiring and connectors are good but motor feed is still shorted, suspect internal motor short — remove motor and bench-test by applying known supply through a fused jumper and measuring current draw (observe safety procedures).
- If motor bench test confirms internal short, replace motor/regulator assembly as required. If bench test is good, investigate body/window control module outputs for internal short or replace module per manufacturer guidance.
- Clear codes and retest window operation and re-scan to confirm the fault does not return.
Likely causes
- Internal motor short (most common)
- Wiring damage at door hinge/boot where harness flexes
- Pincorrosion or contamination in the motor or switch connector
Fault status
Status
B1413 — Driver-side electric window motor short to ground detected.
