If the air blows only from the defroster vents, whether using the heater or air conditioning, and regardless of which mode is selected, you most likely have vacuum-operated mode doors, and a break in the vacuum hose. On most cars the mode doors are spring-loaded to default to the defrost position for safety reasons. Your feet might freeze but the windshield will be clear.
There should be a vacuum hose routing diagram under the hood, on a sticker. Look on that for a small hose and check valve going through the firewall. Check if that hose is cracked or disconnected.
