Not sure if this has been asked before, I can't find an answer. I have and 04 Expedition and the drivers side temp won't change, it's stuck on heat. When I turn on the a/c and drop the temp from 90* to 60* it blows heat out of the drivers side, but will blow cold out of the passenger side. The a/c works, i know that, it just won't drop the temp on the drivers side every time. It will sometimes, but not always. Any ideas?
