Solution

1. Preparation

Gather tools and parts.
Tools Required: Screwdriver set, multimeter, OBD-II scanner, wire strippers, soldering iron.
Parts Required: New wiper motor (if faulty), new fuse, wiper switch (if defective).
Disconnect the battery to ensure safety.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found in the driver's side footwell or under the dashboard.
Remove the fuse for the windshield wipers using a fuse puller or pliers.
Inspect the fuse for a break in the filament; replace it with one of the same amperage if necessary.

3. Test and Replace the Wiper Motor

Locate the wiper motor, usually under the cowl cover at the base of the windshield.
Disconnect the wiring harness from the motor.
Using jumper wires, apply direct battery voltage to the motor terminals to see if it operates.
If the motor does not operate, remove it by unscrewing the mounting bolts and replace it with the new motor.

4. Check and Replace the Wiper Switch

Remove the steering column cover to access the wiper switch.
Disconnect the wiring harness from the wiper switch.
Use a multimeter to check for continuity across the switch terminals as per the service manual specifications.
If faulty, replace the switch with a new one and reconnect the harness.

5. Reassemble and Test

Reinstall the wiper motor and wiper linkage if previously removed.
Reconnect any disconnected wiring and ensure all components are secure.
Reconnect the battery and test the wipers to ensure they operate correctly.
