Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace the Wiper Fuse

Locate the fuse box (often under the dashboard or near the engine compartment).
Find the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with a new fuse of the same amperage.

3. Inspect and Repair the Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the electrical connector from the wiper switch.
Test the switch continuity with a multimeter; replace the switch if defective.

4. Check and Repair the Wiper Motor

Locate the wiper motor, usually found under the cowl panel at the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Using jumper wires, connect the motor directly to the battery to check for operation.
If the motor does not run, replace it with a new one.

5. Inspect Wiper Linkage

Remove the wiper arms by loosening the nuts at the base using a socket set.
Detach the wiper linkage by removing the retaining clips or bolts.
Inspect the linkage for wear or damage, and replace it if necessary.
Reinstall the linkage and wiper arms, ensuring proper alignment.
