A defroster door is a component of a vehicle's heating and air conditioning system that directs airflow to the windshield and side windows to remove frost, ice, or condensation. It is typically part of the air distribution system and can be controlled manually or automatically. When activated, the defroster door opens to allow warm air to flow onto the glass surfaces, improving visibility and safety while driving.
