Air Delivery
WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
The HVAC control assembly controls the distribution of air by the use of recirculation actuator and the mechanically controlled mode door. The modes that may be selected are:
- Defrost - Air flow is directed at the windshield
- Defog - Air flow is split between the windshield and floor
- Vent - Air flow is directed to the vents located in the instrument panel
- Bi-Level - Air flow is split between the instrument panel vents and the floor vents
- Floor - Air flow is directed to the floor
The desired air distribution mode can be selected with the air distribution knob at the HVAC control assembly. Depending on the position of the flap, air is distributed through various ducts leading to the outlets in the instrument panel. When the defrost position is selected, the HVAC control assembly will command the recirculation actuator to outside air, reducing window fogging.
