Severity Level 2 — 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
- Warning light or message on dashboard related to the wiper/washer system
- Wipers won't park (return to rest position) when turned off
- Windshield wipers not working, stuck mid-cycle, or only working on one speed
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed wiper motor — internal fault from age, heat cycling, and vibration
- Damaged wiring or corroded connector in the wiper/washer system circuit
- Blown fuse for the wiper/washer system circuit — check before replacing components
- Faulty control module driving the wiper motor
- Loose or corroded ground point shared by the wiper/washer system
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 ($49-81 at shop, free at auto parts store for basic scan)
- Visually inspect the wiper/washer system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $133 diagnostic fee at shop)
- Replace wiper motor if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($50-400)
- Check and replace any blown fuses in the wiper/washer system fuse circuit — if fuse blows again, there's still a short that needs to be found ($4-17 for fuses)
- Perform a wiggle test on the wiper/washer system wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-136 diagnostic labor)
