Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, and replacement parts if necessary.
  • Disconnect the vehicle battery to ensure safety while working on the electrical system.
2. Remove the Wiper Switch
  • Remove the steering column cover by unscrewing the screws with a socket set.
  • Disconnect the wiper switch harness connector.
  • Unscrew and remove the wiper switch from the steering column.
3. Inspect and Replace the Wiper Relay
  • Locate the wiper relay in the fuse box (refer to the owner’s manual for exact location).
  • Pull the relay out and visually inspect it for damage.
  • Replace with a new relay if needed or swap with a similar relay to test functionality.
4. Test/Replace the Wiper Motor
  • Reconnect the battery and turn the ignition to the "on" position.
  • Use a multimeter to check for voltage at the wiper motor connector.
  • If no voltage is present, trace back the wiring to find the issue.
  • If voltage is present but the motor does not operate, remove the wiper motor by unscrewing it from its mounting points.
  • Replace with a new wiper motor if required.
5. Reassemble Components
  • Reconnect the wiper switch and ensure all connectors are securely fastened.
  • Reinstall the steering column cover and secure with screws.
  • Reconnect the battery and test the wipers to ensure they function correctly.
