The video shows a close-up of a car's dashboard, specifically the control panel. A person's hand is seen pressing a button on the panel. The button is labeled "REAR" and is located between the "AUTO" and "REAR TEMP" buttons. The hand presses the button, and the corresponding light on the dashboard turns on, indicating that the rear window defroster has been activated. The video provides a clear view of the button and the light, making it easy to understand the process of activating the rear window defroster.
