Vent Mode

When the driver selects the VENT mode, air is delivered through the instrument panel outlets and a small amount is delivered to the floor. Outside air is brought into the vehicle. Vacuum is supplied to one side of both the mode and defroster actuators. The actuators retract, opening the mode and defroster doors.When the driver selects the VENT mode, air is delivered through the instrument panel outlets and a small amount is delivered to the floor.
