Defroster Vents

There are four defroster vents, two for the windshield and two for the front side windows. The two for the windshield are designed so that the majority of the air is directed up against the windshield. The remaining air trickles out at the bottom edge of the windshield to help keep the windshield wipers free of ice. The air ducts to the side window defrosters are a continuation of the windshield ducts.
