The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - A/C compressor kicking on in "VENT" mode. Any ideas?

Hmmm, this is the only square I've had with AC, but none of my other vehicles have ever ran the compressor on vent. Defrost and bi-level I can see, since it has to run to dehumidify the air for the defroster. But everything I remember from school says the compressor should run in the AC mode, defrost mode, and bi-level/mix mode, but not on vent or floor mode.
