Defroster Vents

Mist forms easily on the windows in cold, damp weather. The defroster vents release air towards the front windows. The air flow removes the mist that forms. As the air is dry, the airflow also prevents moist air from the passenger compartment reaching the glass, so countering misting. The air conditioning contributes significantly to these functions by dehumidifying the air at temperatures above 0 °C.
