Solution

1. Preparation

Gather tools and materials.
Ensure vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace the Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the cover and locate the wiper fuse (refer to the owner’s manual for the exact location).
Inspect the fuse; if it’s blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace the Wiper Relay

Locate the relay for the windshield wipers, usually in the fuse box.
Remove the relay and test it using a multimeter for continuity.
If faulty, replace it with a new relay matching the specifications.

4. Test and Replace the Wiper Motor

Reconnect the battery and activate the wiper control.
If no movement is observed, disconnect the motor wiring connector.
Use a multimeter to check for voltage at the connector while the wipers are activated.
If voltage is present but the motor doesn’t run, replace the wiper motor.
If there’s no voltage, further investigate the wiring and switches.

5. Reassemble Components

If any components were replaced, reinstall them securely.
Ensure all electrical connections are tight and free of corrosion.
Reattach any covers removed during the inspection.
