RE: heater vent only from top
 

SOunds like the Electronic climate control unit is going bad, or the heater blend doors are out of whack. Outside of tearing into the system, the only quick possible fix I can suggest is to remove/disconnect the battery for about a half hour to see if it resets itself. Be sure you have the code to activate the radio again BEFORE you disconnect the battery.
