Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle's battery to ensure safety during repairs.
  • Tools required: flathead screwdriver, multimeter, socket set, and pliers.
2. Inspect and Clean Wiper Control Switch
  • Remove the trim panel around the steering column using a flathead screwdriver.
  • Disconnect the harness from the wiper control switch.
  • Clean the contacts on the switch using electrical contact cleaner.
  • Reconnect the harness and test the switch functionality.
3. Test Wiper Motor
  • Locate the windshield wiper motor under the hood.
  • Disconnect the wiring harness from the motor.
  • Use a multimeter to check for voltage at the motor terminal when the wiper switch is activated.
  • If there is no voltage, replace the wiper control switch; if voltage is present but the motor does not operate, replace the wiper motor.
4. Inspect Wiring Harness
  • Visually inspect the wiring harness connected to the wiper motor and control switch.
  • Look for any frayed wires or loose connections; repair or replace damaged sections as necessary.
  • Reconnect any loose connectors securely.
5. Replace Fuse (if applicable)
  • Locate the fuse box and identify the fuse for the windshield wiper system.
  • Remove the fuse and inspect for continuity using a multimeter.
  • Replace with a new fuse of the same amperage if the old fuse is blown.
