Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box (check the owner's manual for the exact location).
Remove the cover and identify the windshield wiper fuse.
Use a multimeter to check for continuity; replace the fuse if it is blown.
Reinstall the fuse box cover and reconnect the battery.

3. Check the Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector.
Use a multimeter to test the switch for continuity in different positions (low, high, and intermittent).
Replace the switch if it does not show continuity as expected.
Reassemble the steering column cover.

4. Test and Replace the Wiper Motor

Access the wiper motor by removing the wiper arms (use a socket set to remove the nuts).
Disconnect the wiring harness from the wiper motor.
Connect the motor directly to a power source (ensure correct polarity).
If the motor does not operate, replace the wiper motor.
Reinstall the wiper motor and reattach the wiper arms securely.
