Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent any electrical shorts while working.

2. Check and Replace Fuse

Locate the fuse box; refer to the owner’s manual for the exact location.
Remove the windshield wiper fuse using a fuse puller or flathead screwdriver.
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.

3. Inspect and Test Wiper Motor

Locate the wiper motor under the hood.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to test for voltage at the motor connector while the wipers are activated.
If no voltage is present, trace the wiring back to the switch and repair any broken connections.
If voltage is present but the motor doesn’t operate, replace the wiper motor.

4. Test and Replace Wiper Switch

Remove the steering column cover to access the wiper switch.
Disconnect the wiring harness from the wiper switch.
Use a multimeter to test for continuity in the switch.
If defective, replace the wiper switch with a new component.

5. Reassemble and Clean

Reconnect all electrical connectors and ensure all components are secure.
Reassemble the steering column cover and any other displaced parts.
Reconnect the battery and test the wipers for proper operation.
