Gather necessary tools and parts.
Ensure the vehicle is parked safely with the engine off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Wiper Switch

Remove the steering column cover using a screwdriver.
Visually inspect the wiper switch for any loose connections or damage.

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using pliers and inspect it for continuity. Replace if blown with a fuse of the same amperage.

4. Test and Replace Wiper Motor

Verify the wiper motor's electrical connection for corrosion or loose wires.
If the motor is unresponsive, remove it by unscrewing the mounting bolts.
Replace the wiper motor with a new one, ensuring all connections are secure.
