Air Conditioning problem
1992 Ford E-Series Van V8 Two Wheel Drive Automatic 373600 miles

My heater controls don't switch from defrost to vent, floor, or any other setting. The AC compressor comes on when it is set to the correct position, but the air blows out the defrost vents all the time. I have checked the vacuum hoses on the engine and as far as I can see into the dash, coming from the control switch and next to the heater core. Anything else I might be missing?
