Solution

1. Preparation

Gather tools and parts listed below.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shock.

2. Replace Blown Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse; replace it with one of the same amperage if blown.

3. Test and Replace Wiper Motor

Locate the wiper motor (usually under the windshield cowl).
Disconnect the wiring harness from the wiper motor.
Using a multimeter, check for voltage at the motor connector when the wiper switch is activated.
If no voltage is present, troubleshoot wiring or relay issues.
If voltage is present, connect the motor directly to the battery to test functionality; replace the motor if it does not operate.

4. Inspect and Replace Wiper Relay (if necessary)

Locate the wiper relay in the fuse box.
Remove the relay and test it using a multimeter for continuity.
Replace the relay if it fails the test.

5. Check and Repair Wiring

Inspect the wiring harness for any cuts, corrosion, or loose connections.
Repair or replace damaged wires as necessary.
Ensure all connectors are securely fastened.
