Disconnect the battery to prevent electrical shorts.

2. Fuse Replacement

Locate the fuse box, typically found under the dashboard on the driver's side.
Remove the cover and locate the wiper fuse using the diagram on the fuse box cover.
Use a fuse puller or pliers to remove the faulty fuse and replace it with a new one of the same amperage.

3. Wiper Motor Testing

Reconnect the battery.
Access the wiper motor, usually located under the plastic cowl at the base of the windshield.
Disconnect the motor connector.
Use jumper wires to connect the motor directly to the battery to test if it runs.
- Positive lead to the positive terminal and negative lead to the negative terminal.

4. Repair or Replace Wiper Motor

If the motor does not operate, proceed to remove it:
- Remove any screws or bolts securing the motor.
- Disconnect the linkage from the wiper arms if necessary.
- Carefully pull the motor out of its mounting position.
Install a new wiper motor by reversing the removal steps.

5. Reassemble

Reconnect any disconnected wiring harnesses.
Ensure the wiper arms are reattached properly.
Reinstall the plastic cowl and secure it with screws.
Reconnect the battery and test the wipers.
