Ceiling. Cold air fails

the middle vents only supply air from the ac unit using a separate in dash fan. the floor and defrost vents come only from the heater
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
My ac blows fine through the overhead, floor and side vents but intermittentely throught the front vents. What might be the cause?
assuming this is Home AC question - speed up the AC fan speed
It should blow through the floor vents. Modern vehicles generally use movable baffles in there HVAC systems, to direct air flow where the controls indicate. If the controls allow airflow to the floor, but nothing flows out, there is a malfunction between the control switch and the actuator that directs the flow.
