Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and pliers.
Disconnect the vehicle battery to prevent electrical shorts.

2. Inspect the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and locate the fuse for the windshield wipers (refer to the owner's manual for the exact location).
Inspect the fuse for any signs of being blown; replace if necessary with a fuse of the same amperage.

3. Test the Wiper Switch

Remove the steering column cover using a flathead screwdriver.
Disconnect the wiper switch harness.
Use a multimeter to check for continuity across the switch terminals when activated.
If there is no continuity, replace the wiper switch.

4. Inspect and Test the Wiper Motor

Locate the wiper motor, usually found under the cowl panel at the base of the windshield.
Disconnect the motor's electrical connector.
Using a multimeter, check for voltage at the connector when the wiper switch is activated.
If there is voltage but the motor does not work, replace the wiper motor.
If no voltage is present, trace the wiring back to the switch for any faults.

5. Check the Wiper Linkage

With the wiper arms removed, inspect the linkage for wear or disconnection.
Manually move the linkage to ensure it operates smoothly; reattach or replace if damaged.
Reinstall the wiper arms securely onto the motor shaft.

6. Final Assembly

Reconnect the wiper motor and switch.
Reinstall the steering column cover and fuse box cover.
Reconnect the battery.
