Thanks for all the help everyone. The problem was, as I suspected in the first place, the heater-a/c control module. I priced a new one at a dealer, and got a price of $254. I then went to a junkyard, picked one up for $35, and have the air blowing out any vent I would like. I don't know the exact location of the problem within the module, or what happened, but my suspicion, based on how "loose" the selector know was, was correct. Thanks again for all the help.
