Similar problem for the last 2 years on mine. Blows hot air for about 10 minutes, then instantly icy cold. One major difference though - I have no aux fan on mine. 2005 4.4, and it did not come with the aux fan. Apparently some did and some didn't. No clue why, or why it won't blow cold until it feels like it. Other posts on this have revealed nothing except that I'm not the only one with the problem.
