If the heater on my 1996 Lincoln Town Car blows air but it is cold air would it be the heater core or the Blend Door motor?

Did you check the coolant level. There is a range where you will loose heat but yet not overheat the engine. If that is okay, then start by making sure that the thermostat is okay. If it is stuck open during cooler temps, it is possible to get nearly cold air. Many cars (I'm sure yours included) have a water valve located in the heater hose usually not too far from the firewall. The valve are known to fail by either the valve sticking, or the rubber in the valve swelling and completely blocking water passage. It is not very likely for the heater core to become so badly blocked as to get only cold air, but if that were the case you could tell by feeling hoses going to the heater core. One would be hot and the other would be cold. This would also be the case if the valve is not allowing water passage.

if the compressor is running and it is still blowing hot air i would have to say that the blend door is not operating properly. if the blend door is stuck open then the air is still blowing across the heater core and into the cabin. replacing the motor that controls the blend door will most likely fix this problem

There is no heater fuse, the heater works by having hot coolant run threw a heater core that's inside the dash, then when you turn the heat on, the blower motor blows threw the heater core, sending the hot air inside the vehicle.
