Solution
1. Preparation
  • Gather necessary tools and materials.
  • Ensure the vehicle is parked on a level surface and the ignition is turned off.
  • Disconnect the 12V battery to ensure safety during repairs.
2. Inspect and Replace Fuse
  • Locate the fuse box under the dashboard or in the frunk (front trunk).
  • Identify the wiper fuse using the fuse diagram.
  • Remove the fuse using a fuse puller.
  • Inspect the fuse; if blown, replace it with a new one of the same amperage.
3. Check the Wiper Motor
  • Reconnect the battery.
  • Use a multimeter to check the voltage at the wiper motor connector while activating the wiper switch.
    • Set the multimeter to DC voltage and check for power (typically 12V).
  • If no power is present, follow the wiring to check for breaks or bad connections.
  • If power is present and the motor does not operate, proceed to replace the wiper motor.
4. Replace the Wiper Motor (if necessary)
  • Remove the wiper arms by unscrewing the retaining nuts and using a puller if needed.
  • Disconnect the wiper motor electrical connector.
  • Remove the motor mounting screws and take out the motor.
  • Install the new wiper motor in reverse order, ensuring to secure all screws and reconnect the electrical connector.
  • Reattach the wiper arms in the correct position.
