Solution

1. Preparation

Gather tools:
- Multimeter
- Fuse puller
- Screwdriver set
- Wire connectors (if needed)
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check the Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller to remove the wiper fuse.
Inspect the fuse visually; if it is blown, replace it with a new fuse of the same amperage.

3. Inspect the Wiper Control Stalk

Remove the steering column cover using a screwdriver.
Check the wiper control stalk for any visible damage or loose connections.
If damaged, replace the wiper control stalk.

4. Test the Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for power at the connector when the wiper switch is activated.
If power is present, the motor is likely faulty; replace the wiper motor.
If no power, trace the wiring back to the fuse box for issues.

5. Examine Wiring and Connectors

Inspect the wiring harness connected to the wiper motor for any frays or damage.
Repair or replace any damaged wires or connectors.

6. Check Windshield Washer Pump

Locate the washer fluid reservoir and check the pump connections.
If the pump is not functioning, replace the washer pump.
