This happend to mine, so Im guessing you have the same problem. Under the hood and in the back, along the firewall. Close to the top and middle you will see a vacuum tree. Check there for any of those lines having a tear or just came off. One of my hoses had dry rotted. An air leak there will cause your defrost to not work

Why would a 95 Ford Explorer AC cyle on and off when the switch is in defrost or heater position?
On my 1995 Ford Explorer when the defrost position is selected , and the temperature knob is set in the red area to get heated air to defrost the windshield , the A/C compressor will cycle on and off to help dehumidify the air, but the compressor ONLY cycles on and off in the DEFROST POSITION ( sorry if I'm misinterpretting your question )
Why would air only blow out of the defrost vent on a Ford Tempo?
The first answer is correct and heres where the leak most likely is. Under the hood, against the back firewall close to the middle, you'll see a vacuum tree. Several hoses plug in here. Both the Tempo and Topaz I've had this happen to, occured here. Look for a unplugged hose or a cracked or dry-rotted hose and replace as needed. Defrost is the AC/heat system's default position. Likely you have lost vacuum to the control head. When there is no vacuum to control the functions then it will default to the defrost vents.
