Solution
1. Preparation
  • Gather tools: Basic socket set, multimeter, OBD-II scanner.
  • Park the vehicle on a flat surface and ensure the engine is off.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect Wiper Control Switch
  • Remove the steering column cover using a socket set.
  • Disconnect the electrical connector from the wiper control switch.
  • Test the switch with a multimeter to ensure it is functioning correctly. If defective, replace the switch.
3. Check Wiper Relay
  • Locate the wiper relay in the fuse box (refer to the owner's manual for location).
  • Remove the relay and test it using a multimeter for continuity.
  • If the relay is faulty, replace it with a new one.
4. Inspect Wiring and Connections
  • Visually inspect the wiring harness connected to the wiper motor.
  • Look for frayed wires or loose connections; repair or replace as necessary.
  • Ensure all connections are secure and free from corrosion.
5. Test Wiper Motor and Park Switch
  • Reconnect the battery terminal.
  • Use a multimeter to check if the wiper motor is receiving power when the switch is off by accessing the motor connector.
  • If the motor is still running continuously, check the park switch functionality. If faulty, replace the wiper motor.
