Typical repair cost: $120 – $600
Severity Level 1 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Power windows not responding to controls — stuck in one state
- Battery draining overnight or when vehicle is parked
- Power window won't go up or down — stuck in current position
- Excessive current draw on the power window system circuit (fuse may blow repeatedly)
Possible Causes
- Damaged wiring in the power window system harness shorted to a 12V power source — wiring insulation chafed through from rubbing against metal body panels
- Water intrusion or corrosion in power window system electrical connector causing internal short to battery voltage
- Failed window motor/regulator — internal short to power within the component
- Aftermarket accessory installation tapped into the wrong circuit, back-feeding 12V
- Window regulator mechanical failure — cable snapped or pulley broken, motor runs but glass doesn't move
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($10-83 at shop, free at auto parts store for basic scan)
- Visually inspect the power window system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $65 diagnostic fee at shop)
- Repair or replace damaged section of wiring harness where short is located — solder and heat-shrink all connections, don't use crimp connectors on critical circuits ($130-368 depending on accessibility)
- If window motor/regulator is internally shorted, replace with a quality OEM or OEM-equivalent aftermarket unit ($100-500)
- Clean all ground points related to the power window system — remove bolt, sand contact surface to bare metal, apply dielectric grease, and torque to spec ($72-178 at shop)
