Solution

1. Preparation

Gather tools including a multimeter, socket set, and screwdrivers.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Replace Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the wiper fuse using the diagram on the inside of the cover.
Pull out the fuse and inspect it. If the metal filament is broken, replace it with a new fuse of the same amperage.

3. Inspect and Replace Wiper Switch (if needed)

Remove the steering column cover using a screwdriver.
Disconnect the wiring harness from the wiper switch.
Use a multimeter to check for continuity in the switch. If no continuity is present, replace the switch with a new one.
Reconnect the wiring harness and replace the steering column cover.

4. Test and Replace Wiper Motor (if needed)

Locate the wiper motor, typically found at the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Using jumper wires, connect the motor directly to the battery to test for functionality.
If the motor does not operate, remove the mounting bolts and replace the motor with a new unit.
Reconnect the electrical connector and secure the motor in place.

5. Reassemble and Test

Reattach any components that were removed during the process.
Reconnect the negative battery terminal.
Test the wipers to ensure they operate correctly across all settings.
