Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and locate the windshield wiper fuse.
Check the fuse for continuity; if blown, replace it with a fuse of the same amperage.

3. Test and Replace Wiper Switch (if necessary)

Remove the steering column cover to access the wiper switch.
Use a multimeter to test the switch for continuity when activated.
If faulty, disconnect the wiring harness and remove the switch.
Install a new wiper switch by reversing the removal process, ensuring all connections are secure.

4. Inspect and Repair Wiring

Examine the wiring harness leading to the wiper motor for any signs of damage.
If damaged, repair the wiring using appropriate methods (soldering or heat shrink).
Ensure all connectors are clean and firmly attached.

5. Test and Replace Wiper Motor (if necessary)

If previous steps do not resolve the issue, remove the wiper motor.
Disconnect the electrical connector and remove the motor from its mount.
Install a new wiper motor by reversing the removal process, ensuring proper torque specifications are followed for mounting bolts.
