Does air come out of the dash outlets when the A/C is off and the fresh air/vent is turned on? If yes, then the problem is unique to the A/C pathway/controls, and air must not be moving through it. There may be an obstruction in the A/C plenum or air ducts, perhaps a stuck valve. But if no, and neither fresh air nor A/C air is moving, then I suspect your ...
