Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the windshield wiper system using the diagram on the fuse box cover.
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.

3. Test and Replace the Wiper Motor

Reconnect the battery and activate the wiper switch to check for operation.
If the wipers still do not function, disconnect the battery again.
Remove the wiper arms by unscrewing the retaining nuts using a socket set.
Detach the cowl panel to access the wiper motor.
Disconnect the motor's electrical connector and remove the mounting bolts.
Test the motor by connecting it directly to the battery; if it does not run, replace the wiper motor.
Install the new motor by reversing the removal steps, ensuring all connections are secure.

4. Inspect Wiring and Connectors

Examine the wiring leading to the wiper motor for any frays or breaks.
Clean and secure any corroded connectors with electrical cleaner and dielectric grease.
Reassemble all components after ensuring the wiring is intact.
