Air distribution system: General
The air distribution system distributes the air to the passenger compartment. It is used jointly by the heating system and the cooling system in the climate control system. The blower fan draws air into the system. Fresh air enters through the fresh air intake in the distribution housing under the plenum chamber.
The air passes through the filter and the evaporator, past the temperature damper and possibly though the heat exchanger, before being released into the passenger compartment through the vents.
The temperature of the air from all the air vents can be controlled separately for the right or left hand sides.
After circulating, the air disappears out of the passenger compartment though air vents at the rear of the vehicle.
