Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the battery to ensure safety while working on the electrical system.
2. Inspect and Replace Wiper Switch
  • Tools Required: Screwdriver set, multimeter
  • Locate the steering column cover and remove it using a screwdriver.
  • Disconnect the wiper switch harness.
  • Use a multimeter to test the continuity of the wiper switch in various positions. If defective, proceed to replace.
  • Install the new wiper switch by connecting the harness and reassembling the steering column cover.
3. Check and Replace Wiper Relay
  • Tools Required: None
  • Locate the fuse box under the dashboard or hood (refer to the owner’s manual for the specific location).
  • Identify the wiper relay using the diagram on the cover.
  • Remove the relay and test it for continuity with a multimeter. Replace if faulty.
  • Reinstall the new relay in the same position.
4. Inspect Wiring and Connections
  • Tools Required: Wire strippers, electrical tape
  • Visually inspect the wiring harness connected to the wiper motor for damage.
  • Repair any frayed wires using wire strippers and electrical tape or replace the harness if necessary.
5. Test Wiper Motor
  • Tools Required: Jumper wires
  • With the battery reconnected, apply direct power to the wiper motor using jumper wires to confirm functionality.
  • If the motor runs properly, the issue may be with the control circuit; if not, replace the wiper motor.
