Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Fuse Inspection

Locate the fuse box (refer to the owner's manual for specific location).
Remove the fuse for the windshield wipers using a fuse puller or flathead screwdriver.
Inspect the fuse for continuity; if blown, replace with a fuse of the same amperage.

3. Wiper Motor Testing

Disconnect the wiper motor electrical connector.
Using a multimeter, set to measure voltage, check for power at the connector while operating the wiper switch.
- If no voltage is present, investigate the wiring harness and switch.
If voltage is present, reconnect the motor and test its operation directly by applying 12V to the motor terminals.

4. Wiper Switch Replacement (if necessary)

If the wiper switch is determined to be faulty, remove the steering column cover by unscrewing the screws securing it.
Disconnect the switch wiring harness and remove the switch from the steering column.
Install the new switch by reversing the removal process and secure it with screws.

5. Reassemble Components

Reattach any covers or components removed during the process.
Ensure all wiring is secured and no tools are left in the engine bay.
