Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the fuse for the wipers using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with the same amperage rating.
Reinstall the fuse and reconnect the battery.

3. Test the Wiper Switch

Remove the steering column cover to access the wiper switch.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the switch is activated.
Replace the switch if it fails the continuity test.

4. Test and Replace the Wiper Motor

Locate the wiper motor, usually beneath the cowl panel.
Disconnect the motor’s electrical connector.
Use a multimeter to check for power at the connector when the wiper switch is activated.
If power is present and the motor does not function, remove the motor by unscrewing it from its mount.
Install a new wiper motor if the old one is faulty.

5. Inspect Wiper Linkage

Remove the wiper arms by unscrewing the retaining nuts.
Carefully pull off the wiper arms and set them aside.
Inspect the wiper linkage for any signs of wear, damage, or disconnection.
If damaged, replace the wiper linkage assembly.
