Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the ignition.
Disconnect the negative battery terminal to ensure safety.

2. Check the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and locate the wiper fuse (refer to the diagram).
Inspect the fuse; if blown, replace it with one of the same amperage.

3. Inspect the Wiper Switch

Remove the steering column cover to access the wiper switch.
Test the switch with a multimeter to ensure it is sending power to the wiper motor.
Replace the wiper switch if it does not function correctly.

4. Test the Wiper Motor

Reconnect the battery and turn on the ignition.
Use a multimeter to check for voltage at the wiper motor connector when the switch is activated.
If voltage is present and the motor does not operate, replace the wiper motor.

5. Examine Wiring and Connectors

Inspect the wiring harness leading to the wiper motor for frays or breaks.
Clean any corroded connectors and ensure they are securely connected.
Repair or replace damaged wiring as necessary.

6. Inspect Wiper Linkage

Remove the wiper arms by loosening the nuts at the base of each arm.
Disconnect the wiper linkage and inspect for wear or obstructions.
Lubricate or replace the linkage as needed and reassemble the components.
