help...heat

when I turn my heat on full blast it only blows out cold air. I recently had my AC recharged..does this have something to do with it?

The a/c will cycle ocassionaly when you have your heat on. The a/c is used in this capacity to make sure you get "dry heat" instead of moist heat, to answer your question,,,, no , i do not think so. I think there may be a door in the dash that, depending on whether you have the cold or heat sellected, that will block of the heat or the cold duct. It may be jammed in the a/c position.
