Air Delivery
WARNING: This page is about a different car, the 2009 Pontiac Torrent and 2009 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
The defrost, panel and floor actuators control air delivery. The HVAC control module controls these actuators in order to distribute airflow to a desired outlet. When the vehicle operator selects the defrost, mix-blend or floor positions, the A/C compressor clutch engages and the recirculation actuator will be moved to the outside air position. The flow of air during the various modes of operation is as follows:
- Panel-Outside Air and Recirculation inlet air setting, full air from Instrument Panel (I/P) outlets
- Bi-Level-I/P and front and rear floor outlets
- Floor-Small amount of air to the right and left side window outlets and a larger amount of air to the Front and Rear floor outlets
- Mix-Blend-Floor and defroster outlets with a slight bleed to the I/P outlets
- Defrost-Defrost outlets with a small amount of air to the right and left side window outlets and to the Driver Side floor outlet and a very small amount to the Rear floor outlet
