Your a/c and heater blow thru the defrost ( top of dash? ) and the vents. Or defrost/or the vents.? and not on the floor? Well all of these should work. can you hear the motor inside the dash turning to they're perspective spots on the dial the motor pulls a cable and closes or opens appropriate doors as the selector switch is moved. if not the switch may be faulty. and you can get it from a parts store or dealership. CK the parts store's first they will be cheaper and will be able to give you a look at what needs to be done to replace it. But it can be done on most "fine " cars in 20- 30 min with minimal hand tools.

1996 ford windstar blowes cold air thru defrost only warm in back

For some reason this question was listed a dozen times within an hour or so.
Usually the problem is a blend door under the dash. The blend doors direct air thru the heater core and the vents.

No heat - ac stays on blowing through defrost vents

If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.
