Solution

1. Preparation

Gather the necessary tools: screwdriver set, multimeter, and replacement fuse (if needed).
Park the vehicle safely and turn off the ignition.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the trunk.
Remove the fuse cover and identify the windshield wiper fuse using the diagram.
Use a multimeter to test the fuse for continuity; replace it with a new fuse of the same amperage if it is blown.

3. Inspect and Test Wiper Motor

Access the wiper motor by removing the plastic cowling at the base of the windshield (typically requires a screwdriver).
Check the electrical connections; ensure they are secure and free of corrosion.
Test the wiper motor directly with a multimeter to confirm it receives power when the wiper control is activated.
If there is no power, trace wiring back to the control switch; repair any damaged wiring.

4. Replace Wiper Motor (if necessary)

If the motor is faulty, disconnect it from the electrical harness and remove the mounting bolts.
Install the new wiper motor by reversing the removal steps; ensure it is securely fastened.
Reconnect the electrical harness and test the wipers again.
