Air Speed (Auxiliary): Notes

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

There are 2 separate control assemblies for the auxiliary HVAC system. There is the front auxiliary HVAC control assembly and the rear auxiliary HVAC control assembly. Both control assemblies provide input to the auxiliary HVAC control processor. If the front auxiliary HVAC control assembly is in any other position than OFF or REAR, the auxiliary HVAC control processor will only use inputs from the front HVAC controls. If the front auxiliary HVAC control assembly is in the REAR position, then the system will only function with inputs from the rear auxiliary HVAC control assembly. If the front auxiliary HVAC control assembly is in the OFF position, then the auxiliary HVAC control processor does not respond to input from either control assembly. The auxiliary HVAC control processor can not request A/C compressor clutch engagement from the PCM. The rotary switches on the auxiliary HVAC control assembly and the front auxiliary HVAC control assembly provide the operator the ability to select several blower speeds.
