I' m just a shade tree mechanic, but any problems of this sort turned out to be a heater core. Just replaced one in our work truck (Dodge). It did the same thing. The moisture on the winshield is usually a good clue. Once agaiin I am no certified mechanic, just an old trial and error guy. Good Luck, Justin
Oh, sometimes you may also smell antifreeze.
