Which Actuator Do You Need?
RECIRCULATION
Controls the intake of air into the system, either bringing outside air in or using inside air in recirculation.
BLEND
Controls the temperature of the air flowing from the vents by mixing hot and cold air from the heater core and the evaporator core.
MODE
Controls which vents have air flow, i.e. Floor, Panel or Front, Defrost, or any combination of those.

Main vs. Auxiliary
The term "Main" refers to the air flow control of the Front Vents. The term "Auxiliary" refers to the air flow control of the Rear Vents.
Many actuators that control the air flow to the rear vents are still located in the front of the vehicle. Some larger and/or higher end vehicles may have Auxiliary air door actuators in the center console or in the rear of the vehicle.
