Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Check and Replace the Wiper Fuse

Locate the fuse panel, usually found under the dashboard or in the engine compartment.
Identify the wiper fuse based on the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage (typically 10A for wipers).

3. Inspect and Replace the Wiper Motor

If the fuse is intact, reconnect the battery terminal and turn on the ignition.
Remove the plastic cover from the wiper motor, if applicable.
Disconnect the wiring harness from the wiper motor.
Use a socket set to remove the bolts securing the wiper motor to the vehicle.
Install the new wiper motor by reversing the removal steps, ensuring proper alignment and secure fit.

4. Test the Wiper Switch

If wiper motor replacement does not resolve the issue, test the wiper switch.
Remove the steering column cover to access the wiper switch.
Use a multimeter to test for continuity at the switch terminals when activating the wiper settings.
If the switch is faulty, replace it with a new switch.
