✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.
Typical repair cost: $100 – $500
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 functioning as expected
- Window moves slowly or only works from one switch
- Power window won't go up or down — stuck in current position
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed window motor/regulator — internal fault from age, heat cycling, and vibration
- Damaged wiring or corroded connector in the power window system circuit
- Blown fuse for the power window system circuit — check before replacing components
- Faulty control module driving the window motor/regulator
- Loose or corroded ground point shared by the power window system
- 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 ($20-105 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, $72 diagnostic fee at shop)
- Inspect the wiring boot where it passes from the body into the door — this is the #1 failure point. Peel back the rubber boot and check for broken/cracked wires ($0 DIY inspection)
- Replace window motor/regulator if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($100-500)
- Check and replace any blown fuses in the power window system fuse circuit — if fuse blows again, there's still a short that needs to be found ($2-17 for fuses)
