Are you referring to automotive air conditioning systems? It could be a faulty compressor. It could also be a malfunction of the air door, which mixes air from the heater and air conditioning to provide finer temperature control.
The most common cause of an air conditioner not blowing air is a plugged filter. Be sure your filter is clean.

If a 1988 Lincoln Town Car is blowing both hot and cold air when the air conditioning is on, there could be a problem with the thermostat. There might also be a problem with the level of refrigerant in the air conditioning pump.
The air comes from the air outside and the air conditioning system in the car turns this into cold or warm air.
Air conditioning is removing hot air with cold air. For example we use air conditioner that removes hot air by blowing cold air from a refrigeration cycle into a room.
