If no activity, remove the wiper arms by unscrewing the retaining nuts and pulling them off.
Disconnect the electrical connector from the wiper motor.
Remove the motor from its mounting by unscrewing it from the bracket.
Inspect the motor for signs of wear or damage; if defective, replace it with a new motor.

4. Reassemble Components

Install the new wiper motor by reversing the removal process.
Reconnect the electrical connector securely.
Reattach the wiper arms, ensuring they are in the correct resting position.
