Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the ignition.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse for a break in the filament. If broken, replace with an equivalent amperage fuse (typically 15A for wipers).

3. Replace Wiper Motor (if diagnosed as faulty)

Remove the wiper arms using a socket set to loosen and remove the nuts.
Remove any cover panel if necessary to access the wiper motor.
Disconnect the electrical connector from the wiper motor.
Unbolt the wiper motor from its mounting points and remove it from the vehicle.
Install the new wiper motor in reverse order of removal, ensuring proper alignment.
Reconnect the electrical connector and secure the wiper arms back in place.

4. Test Wiper Switch

If the wiper motor is not faulty, check the wiper switch.
Remove the steering column cover to access the switch.
Use a multimeter to check for continuity when the switch is activated.
If the switch is defective, replace it by disconnecting the wiring harness and unbolting it from the column.
