Sounds like the blend door that opens and closes between the heater core for heat and the evaporator for A.C is not operating correctly most of the time the cable that operates the door is broken or has come off.

Check the ductwork behind the dash. One of the air ducts coming from the blower could be off or mispositioned. If this is a situation where the air blows strong at first, then gradually tapers off, the evaporator core (cooling coil) for the air conditioning is freezing up and blocking the airflow. HTH. -Jim

Your car also has a rotary vacuum diverter device on the back side of the heater control panel that determines which damper gets pulled by its vacuum line. These diverters are notorious for breaking at the age of your car but can be simply repaired by replacing the main shaft with a machine screw and nut.
