Ventilation System
Flow-Through Ventilation:
DESCRIPTION General Motors vehicles have a "flow-through" ventilation system. A supply of outside air ("ram" air) flows into the vehicle when the
blower motor is running.
With the side windows closed, air will flow into the front air inlet grilles, through the vehicle and out the rear air exhaust valves.
