Common Symptoms
- Windshield wipers not working or completely dead
- Windshield wipers blowing fuses when activated
- Wipers won't park (return to rest position) when turned off
- Zero voltage on the wiper/washer system circuit — short pulls signal to ground
Possible Causes
- Chafed or pinched wire in the wiper/washer system circuit — wire insulation worn through, copper touching vehicle chassis/ground
- Failed wiper motor with internal short to ground — most common when the component gets wet or overheats
- Corrosion in the electrical connector allowing current to leak to the connector shell/ground
- Damaged wiring harness where it passes through a body panel grommet or near a sharp metal edge
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 ($32-144 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, $64 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 ($158-213 depending on accessibility)
- If wiper motor is internally shorted, replace with a quality OEM or OEM-equivalent aftermarket unit ($50-400)
- Clean all ground points related to the wiper/washer system — remove bolt, sand contact surface to bare metal, apply dielectric grease, and torque to spec ($62-185 at shop)
