Air Distribution System: Notes

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 is taken from through the gap between the hood and the windshield.

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.

After circulating, the air disappears out of the passenger compartment though air vents at the rear of the vehicle.
