Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Ensure the vehicle is parked on a level surface.

2. Check and Replace the Wiper Fuse

Locate the fuse box (typically found under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller.
Inspect the fuse for any signs of damage; replace if blown.
Reinstall the new fuse and reconnect the battery.

3. Inspect and Repair the Wiper Motor

Remove the wiper arms using a wiper arm puller.
Disconnect the wiper motor connector.
Use a multimeter to check for power at the wiper motor connector when the switch is activated.
If no power is present, trace back to the switch and relay.
If power is present but the motor does not operate, replace the wiper motor.

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

Remove the steering column cover to access the wiper switch.
Disconnect the switch connector and test the switch using a multimeter.
If the switch is faulty, replace it with a new one and reassemble the steering column.

5. Reassemble and Finalize

Reinstall the wiper arms and ensure they are properly aligned.
Reconnect the battery.
Test the wipers on all settings to ensure proper operation.
