Vent Mode

When VENT is selected, air is delivered through the instrument panel outlets with a small amount of air delivered to the floor. Vacuum is applied to the mode actuator through the Red vacuum line, and to the Defrost actuator through the Blue vacuum line. The Mode actuator will retract, closing the Heat Door. The Defroster actuator will retract, closing the Defroster Door and opening the Vent Door.
