Section 16 (Heating & Air Conditioning (Service Information)): Operation: Operation: Notes
WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
The heating and A/C systems used in this vehicle are blend-air type systems. In a blend air system, a blend-air door controls the amount of conditioned air that is allowed to flow through, or around the heater core. In the front Dual Zone system, separate blend-air doors are used to provide completely independent side-to-side temperature control of the discharge air. The temperature controls determine the discharge air temperatures by operating the blend door actuators, which move the blend-air doors. This design allows almost immediate control of output air temperatures.
