Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a flat surface and set the parking brake.
  • Disconnect the 12V battery to prevent electrical shorts during repair.
2. Inspect and Replace Wiper Control Stalk
  • Tools Required: Torx screwdriver set, trim removal tools.
  • Remove the steering column cover by unscrewing the screws and gently prying it off.
  • Disconnect the wiper control stalk's wiring harness from the steering column.
  • Replace with a new wiper control stalk assembly if faulty.
  • Reconnect the wiring harness and reassemble the steering column cover.
3. Check and Replace Wiper Relay
  • Tools Required: Pliers, multimeter (if testing is necessary).
  • Locate the wiper relay in the fuse box (refer to the owner's manual for exact location).
  • Remove the relay and test it for continuity with a multimeter; replace if faulty.
  • If no spare relay is available, swap with another relay of the same type temporarily to test functionality.
4. Inspect Wiper Motor
  • Tools Required: Socket set, multimeter.
  • Remove the wiper arms using a puller tool if necessary, to access the wiper motor.
  • Disconnect the wiper motor connector and test for proper voltage with a multimeter.
  • If the motor does not receive power, trace the wiring back to the control stalk and relay.
  • If the motor is faulty, replace it with a new wiper motor assembly.
