CHEVROLET TRUCK FLOOR PROBLEM

1985 Chevrolet Truck • 129,000 miles

The heater controls are stuck on floor. No matter what you do it does switch to defrost/vent or nothing. I pulled dash apart and everything appears to be working but obviously something isnt. Any ideas?

It is vacuum controlled. Make sure there is source vacuum to the control head.
