Re: 1981 corvette air conditioner ventilation
Hi
this is because
1.there is some blockage in the line comin up and to sides.
2.the selector switch is not properly functioning. the flaps got stuck and it may allows only air to pass through the floor vents.
please vote me if my answer was useful to you.
It can also mean you have a vacuum line broken in your engine compartment that will prevent the valves to open or close at your control. Check for hisses around the engine when engine is at idle
