The A/C system will run, regardless of the temperature setting, on max a/c, a/c, bi-level, and defrost. If you have automatic climate control it will run anytime the outside temperature is above 35°F. This is to dehumidify the air coming into the passenger's compartment and prevents the windows from fogging up. I use the A/C setting year round and adjust the temperature setting for my comfort.
