Air Distribution - Auxiliary Control
WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
The optional auxiliary HVAC system allows the driver to adjust the amount of air directed to the rear of the vehicle using the front mode switch. To direct air to the rear of the vehicle using the floor vents, set the mode switch on the HVAC control module to the FLOOR, DEFROST, or MIX-BLEND modes. To direct air through the headliner vents, set the mode switch on the HVAC control module to the BI-LEVEL or VENT modes.
