2. Inspect and Replace Wiper Blades

Remove the wiper arms by lifting them away from the windshield.
Use a flat screwdriver to release the wiper blades from the arm mounting.
Install new wiper blades by reversing the removal process, ensuring they click securely into place.

3. Check and Replace Wiper Fuse

Locate the fuse box, typically found under the dashboard or hood.
Remove the wiper fuse (refer to the owner's manual for the specific location).
Inspect the fuse for continuity using a multimeter; replace if blown.

4. Test and Replace Wiper Motor

Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for voltage at the connector when the wiper switch is activated.
If there is no voltage, the issue may lie with the wiper switch or wiring.
If there is voltage but the motor does not operate, remove the wiper motor by unscrewing it from its mount and replace it with a new motor.
