Heat blows from dash vents only not floor or defroster

Heat blows from dash vents only not floor or defroster I have a 2007 Dodge Grand Caravan. The dash vents are the only vents that work. It blows hot air so I don't think there is anything wrong with they heating system. There is just no air from floor vents or defroster. Years ago this was controlled by vaccum lines, but now everything is electronic. Any ideas?

We have a 2005 Chrysler TC with the same problem. I have found that resetting the console computer by disconnecting the battery cable, waiting, and then reconnecting it will often "fix" computer-related problems. Also corrected by this method was a door lock problem--lights would flash using remote key fob, but no lock action.
