Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, pliers, screwdrivers.
Disconnect the vehicle’s battery to ensure safety during repairs.

2. Replace the Wiper Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and find the wiper fuse using the diagram.
Pull out the fuse using fuse puller or pliers.
Inspect the fuse for signs of damage; replace it with a new fuse of the same amperage.

3. Test and Replace the Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiring harness from the wiper switch.
Use a multimeter to check for continuity; if there is no continuity when activated, replace the switch.
Reinstall the new switch and reconnect the wiring harness.

4. Inspect and Replace the Wiper Motor (if necessary)

Locate the wiper motor, typically found under the hood near the base of the windshield.
Disconnect the electrical connector from the motor.
Remove the mounting bolts securing the wiper motor to the vehicle.
Install the new wiper motor by reversing the removal process, ensuring all bolts are tightened to the manufacturer's specifications (typically around 10-15 ft-lbs).
Reconnect the electrical connector.

5. Check the Wiper Linkage

Inspect the wiper linkage under the cowl panel if wiper arms are not moving.
Remove the cowl panel by unscrewing it carefully.
Check for any damaged or disconnected linkage; replace or repair as needed.
Reinstall the cowl panel securely.
