Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and ensure it is turned off.
Disconnect the vehicle's battery to prevent electrical shock.

2. Inspect and Replace Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the trunk.
Identify the fuse for the windshield wipers using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with a new fuse of the same amperage.

3. Access and Inspect the Wiper Motor

Remove the plastic cover or cowl panel from the base of the windshield to access the wiper motor.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the connector while the wiper switch is activated.
If no voltage is present, trace the wiring back to the fuse box for potential breaks or shorts.

4. Test and Replace Wiper Motor (if necessary)

If voltage is present but the motor does not operate, remove the wiper motor from its mounting.
Install a new wiper motor by reversing the removal steps. Ensure the motor is securely fastened.
Reconnect the electrical connector and test the wipers again for functionality.

5. Reassemble and Reconnect Battery

Reinstall the plastic cowl cover.
Reconnect the vehicle's battery.
Ensure all tools are removed from the engine compartment.
