Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

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 it if it is blown with a fuse of the same amperage.

3. Inspect and Replace Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector.
Test the switch with a multimeter for continuity in all positions.
If faulty, replace the wiper switch by reversing the disassembly steps.

4. Test and Replace Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector while the wiper switch is activated.
If there is voltage but no motor operation, remove the wiper motor (usually secured by bolts) and replace it with a new motor.
Reconnect the motor and test for operation.

5. Inspect Wiring Harness

Visually inspect the wiring harness connected to the wiper motor and switch for any signs of wear or damage.
Repair or replace any damaged wires and ensure all connections are tight.

6. Check Washer Fluid Pump

Locate the washer fluid pump and disconnect the connector.
Test the pump for power while operating the washer switch.
If the pump does not operate, replace it as necessary.
