Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or engine compartment.
Identify the fuse for the windshield wipers (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers. Inspect for continuity; replace with a new fuse of the same amperage if blown.

3. Inspect and Replace the Wiper Control Switch

Remove the steering column cover by unscrewing the screws and gently prying apart.
Disconnect the wiring harness from the wiper control switch.
Test the switch for continuity using a multimeter; replace if defective.
Reinstall the new switch by connecting the wiring harness and securing the column cover.

4. Test and Replace the Wiper Motor (if necessary)

Access the wiper motor by removing the plastic cowl cover (typically held by clips or screws).
Disconnect the wiring harness from the wiper motor.
Apply direct battery voltage to the motor terminals using jumper wires.
- If the motor does not operate, it will need to be replaced.
To remove the motor, unscrew the mounting bolts and detach it from the linkage.
Install the new motor by reversing the removal steps and reconnecting the wiring harness.

5. Reassemble and Test

Reinstall the plastic cowl cover securely.
Reconnect the negative battery terminal.
Test the wipers at all speed settings and the washer fluid operation.
