Ventilation

The air distribution system provides fresh air ventilation for the passenger compartment in all operating modes. After being warmed to the desired temperature, the air is discharged from the outlets appropriate to the selected operating mode. When all windows are closed, the addition of outside air builds a slight positive pressure within the passenger compartment. The pressure forces stale air to leave the vehicle through a pressure relief valve near the base of the body door lock pillars after it has circulated through the passenger compartment.

Two outboard vents provide ram air ventilation. These vents are installed in the side panels. Two push-pull controls mounted under the instrument panel control the vents. When either vent is opened, air enters the passenger compartment from the pressurized plenum and is directed to the floor.
