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?
Is this a good question?
