Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Fuse Replacement

Locate the fuse box, typically found under the dashboard on the driver's side.
Identify the wiper fuse (consult the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with one of the same amperage.

3. Wiper Switch Inspection

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector and inspect for corrosion or damage.
If faulty, replace the wiper switch with a new one and reconnect.

4. Wiper Motor Testing

Locate the wiper motor, usually beneath the plastic cover at the base of the windshield.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the connector when the wiper switch is activated.
If voltage is present but the motor does not run, proceed to replace the wiper motor.

5. Reassembly

Reinstall any components that were removed, ensuring all connectors and screws are secured properly.
Reconnect the negative terminal of the battery.
