1998 K1500 5.7L. Air conditioning is charged and works great for a while, then stops and starts randomly. A new strange thing I noticed, the vent fan started blowing cold AC air last night even though the AC is not turned on (just fan running). Could this indicate that my intemittant-running AC is caused by something in the dashboard controls? Why else would I get cold AC air blowing when the AC button is not pushed or lit up?
