The heater system is designed to fail in defrost mode, check for damaged or loose vacuum hoses.

Sounds like the switch behind the selector is eithe broken, or stuck in that posiition (or internally) is not moving. I suggest pulling the heater/ac selector unit out and checking the levers from the back side.
Please let me know if you need further assistance.

When the air conditioer is on it blows out the defrost


Does this only with ac setting?
Reason I ask is if it is blowing thru the defroster vents then you have a vacuum leak.Defroster is the default postion(no vacuum).
If it does it when ever you turn on the heater or ac it would most likely be a leak in the supply line(small black vacuum line) that is under the hood and runs thru the firewall at the heat core area. If it only does it when you set the ac then it will be one of the blend doors under the dash leaking most likely.

A/c and heater only blows thru defrost and side vents


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.
