Solution
1. Preparation
  • Gather the necessary tools and parts.
  • Disconnect the vehicle's battery to ensure safety.

Tools Required:

  • Flathead screwdriver
  • Multimeter
  • OBD-II scanner
  • Socket set
2. Inspect and Replace Wiper Control Switch
  • Remove the steering column cover using a flathead screwdriver.
  • Disconnect the wiring harness from the wiper control switch.
  • Use a multimeter to test the switch for continuity in various positions.
  • If faulty, replace the wiper control switch with a new one.
  • Reconnect the wiring harness and replace the steering column cover.
3. Check and Replace Fuse
  • Locate the fuse box in the vehicle (refer to the owner's manual for exact location).
  • Identify the fuse related to the windshield wipers.
  • Pull the fuse out using a fuse puller and inspect it for continuity.
  • Replace with a new fuse of the same amperage if the original is blown.
4. Test Wiper Motor
  • Disconnect the wiper motor's electrical connector.
  • Use a multimeter to measure voltage at the connector while switching the wipers on and off.
  • If no voltage is present, the issue may lie with the control system; otherwise, replace the wiper motor if it is receiving power but not functioning.
