Solution
1. Preparation
  • Gather tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Check and Replace the Fuse
  1. Locate the fuse box, typically found under the dashboard or in the engine compartment.
  2. Identify the wiper fuse using the fuse diagram.
  3. Remove the fuse using a fuse puller or pliers.
  4. Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.
3. Inspect the Wiper Motor and Wiring
  1. Reconnect the negative battery terminal.
  2. Access the wiper motor, usually located under the cowl panel at the base of the windshield.
  3. Visually inspect the wiring harness for fraying or disconnections.
  4. Use a multimeter to check for voltage at the wiper motor connector when the wiper switch is activated.
4. Test and Replace the Wiper Motor (if necessary)
  1. Disconnect the wiper motor connector.
  2. Using a multimeter, apply 12V directly to the motor terminals to test functionality.
  3. If the motor does not operate, remove the motor by unscrewing the mounting bolts.
  4. Replace the faulty wiper motor with a new one and secure it with the screws.
5. Reassemble and Test
  1. Reconnect the wiper motor connector.
  2. Reinstall any components removed for access, such as the cowl panel.
  3. Reconnect the negative battery terminal.
  4. Test the wipers by activating the switch and observing the operation.
