An actuator is a type of motor that is responsible for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion.
An actuator also controls the fresh air or re-circulation modes. These actuators are made up of an electric motor that turns a plastic gear set one direction or the other which is connected to a air control door pivot at the final drive of the unit.
