Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the windshield wiper fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown with an equivalent amperage fuse.

3. Inspect and Replace Wiper Switch

Remove the steering column covers to access the wiper switch.
Disconnect the electrical connector from the wiper switch.
Use a multimeter to test for continuity when the switch is activated.
Replace the switch if faulty, reconnect the electrical connector, and reassemble the steering column.

4. Test and Replace Wiper Motor

Disconnect the wiper motor connector.
Using a multimeter, check for voltage at the connector while the wiper switch is activated.
If no voltage is present, further investigate wiring or switch issues.
If voltage is present, apply direct power to the motor to see if it operates. Replace if non-functional.

5. Inspect and Repair Wiper Linkage

Remove the wiper arms using a puller if necessary.
Check the wiper linkage for wear or damage.
Lubricate the joints or replace the linkage if necessary.

6. Test Washer Fluid System

Ensure the washer fluid reservoir is filled.
Disconnect the washer pump and apply direct power to check operation.
Replace the washer pump if it does not function.
