Solution

1. Preparation

Gather tools including a multimeter, socket set, and screwdrivers.
Park the vehicle on a flat surface and ensure the ignition is off.
Disconnect the vehicle's battery to prevent electrical shock.

2. Check Wiper Control Switch

Remove the steering column cover using a screwdriver.
Access the wiper control switch and disconnect the wiring harness.
Use a multimeter to verify continuity when the switch is activated. Replace if faulty.

3. Inspect and Replace Wiper Fuse

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

4. Test Wiper Motor

Reconnect the battery and turn on the ignition.
Connect the multimeter to the wiper motor terminals to check for voltage when the wiper switch is activated.
If no voltage is present, trace back to the control switch or wiring harness for faults.

5. Inspect Wiper Linkage

Remove the wiper arms using a puller tool if necessary.
Unclip any retaining clips and detach the wiper linkage from the motor.
Inspect for binding or damage; lubricate or replace as needed.

6. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Release the wiper blades from the arms according to the manufacturer’s instructions.
Install new blades ensuring they are securely attached.
