2. Inspect and Repair the Wiper Control Stalk

Remove the steering column cover using the appropriate screwdriver.
Disconnect the wiring connector from the wiper control stalk.
Use a multimeter to test the control stalk for continuity when activated. Replace if defective.
Reconnect the wiring and reassemble the steering column.

3. Test the Wiper Motor

Locate the wiper motor under the hood, typically near the base of the windshield.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for power at the motor connector when the wipers are activated.
If there is no power, check the wiper relay and fuses. If power is present but the motor doesn’t operate, replace the wiper motor.
Reconnect the wiring harness and secure the motor.

4. Replace the Wiper Relay

Locate the fuse box and find the wiper relay based on the vehicle’s manual.
Remove the faulty relay and replace it with a new one.
Ensure it clicks into place securely.

5. Replace the Wiper Fuse

Identify the correct fuse for the wipers in the fuse box.
Use a fuse puller or pliers to remove the fuse.
Inspect the fuse for continuity; replace it if blown with one of the same amperage.
Reinstall the fuse securely.
