Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the wiper fuse and inspect it; if blown, replace it with a new fuse of the same amperage (usually 15A).
Reconnect the battery and test the wipers.

3. Test and Replace Wiper Switch

If the fuse is intact, remove the steering column covers to access the wiper switch.
Use a multimeter to check continuity through the wiper switch.
If faulty, disconnect the wiring harness and replace the wiper switch with a new one. Reassemble the steering column.

4. Inspect and Replace Wiper Motor

If the switch is functional, locate the wiper motor, usually found at the base of the windshield.
Disconnect the power connector and use a multimeter to test for voltage when the wiper switch is activated.
If no voltage is present, further investigate wiring. If voltage is present and the motor does not function, replace the wiper motor.

5. Reassemble and Test

Reconnect all components and ensure everything is securely fastened.
Reconnect the battery and test the wipers for proper operation.
