Solution

1. Preparation

Gather tools: multimeter, socket set, flathead screwdriver, and pliers.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Check the Wiper Switch

Remove the steering column cover using a flathead screwdriver.
Access the wiper switch connector and check for loose connections.
If faulty, replace the wiper switch with a new component.

3. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the wiper fuse (refer to the fuse diagram).
Remove the fuse and check it for continuity with a multimeter.
Replace with a new fuse if defective (ensure correct amperage).

4. Test and Replace Wiper Motor

Locate the wiper motor, typically near the base of the windshield.
Disconnect the wiring harness from the motor.
Apply direct power from the battery to the motor terminals to check functionality.
If the motor does not operate, replace it with a new unit.

5. Inspect Wiper Blades and Arms

Check the wiper blades for wear; replace if they appear cracked or torn.
Ensure wiper arms are securely attached to the motor shaft.
Adjust or replace the wiper arms if they are loose or misaligned.

6. Clear Wiper Fluid System

Check the wiper fluid reservoir; refill if necessary.
Inspect the spray nozzle for clogs and clean with a pin or compressed air.
Test the wiper fluid system by activating the wiper fluid spray.
