Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, and a replacement wiper relay if needed.
  • Disconnect the negative terminal of the battery to ensure safety while working on electrical components.
2. Wiper Relay Inspection
  • Locate the fuse box; typically found in the engine compartment or cabin.
  • Remove the cover and identify the wiper relay (refer to the fuse box diagram).
  • Remove the wiper relay using a socket or pliers.
  • Inspect the relay for any burns or damage; if damaged, replace with a new relay.
3. Wiper Switch Inspection
  • Remove the steering column cover with a socket set.
  • Disconnect the wiper switch connector and use a multimeter to check for continuity when the switch is operated.
  • If the switch shows no continuity or inconsistent readings, replace the wiper switch.
4. Wiring Harness Check
  • Visually inspect the wiring harness for any signs of wear or damage.
  • Use a multimeter to check for continuity in the wires leading to the wiper motor.
  • Repair or replace any damaged wires as necessary.
5. Wiper Motor Testing
  • Reconnect the battery temporarily.
  • Disconnect the wiper motor connector and test the motor by applying direct power from the battery.
  • If the motor operates correctly, the issue may lie with the control circuit; if not, replace the wiper motor.
