Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, flathead screwdriver, and safety gloves.
Disconnect the vehicle battery to ensure safety before working on electrical components.

2. Replace Blown Fuse (if applicable)

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the windshield wiper fuse using the diagram on the lid.
Replace the blown fuse with one of the same amperage rating (usually 10-20 amps).

3. Test and Replace Wiper Switch

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use the multimeter to test the wiper switch: connect probes to the switch terminals and check for continuity when toggling the switch.
If faulty, remove the wiper switch, disconnect the wiring harness, and replace it with a new one.

4. Inspect and Replace Wiper Motor (if necessary)

Remove the plastic cover in front of the windshield to access the wiper motor.
Disconnect the wiring harness from the wiper motor.
Unbolt the wiper motor using the socket set and carefully remove it from the vehicle.
Install the new wiper motor by reversing the removal steps and reconnecting the wiring harness.

5. Reassemble Components

Reinstall the wiper arms and ensure they are positioned correctly.
Replace the plastic cover and secure it with clips or screws.
Reconnect the battery and test the wipers for proper function.
