Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, wire connectors, replacement fuse (if needed), and basic hand tools (screwdriver set, socket set).
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse for the windshield wipers using a fuse puller or needle-nose pliers.
Inspect the fuse for any visible damage or breakage. If blown, replace it with a fuse of the same amperage.

3. Test Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for power at the motor connector while operating the wiper switch.
If power is present but the motor does not operate, replace the wiper motor.

4. Replace Wiper Switch (if necessary)

Remove the steering column cover using a screwdriver.
Disconnect the wiring harness from the wiper switch.
Remove the old wiper switch and install the new one.
Reconnect the wiring harness and reassemble the steering column cover.

5. Reassemble and Test

Ensure all components are reconnected, and the fuse is replaced if necessary.
Turn on the ignition and test the wiper operation at various speed settings.
