Disconnect the negative battery cable.Discharge and recover the air conditioning system refrigerant.Disconnect the refrigerant lines from the evaporator. Plug the openings to prevent contamination.Disconnect the refrigerant lines from the accumulator. Plug the openings to prevent contamination.Remove the accumulator.Drain the cooling system into a clean container for reuse.Disconnect the heater hoses from the heater core tubes.Remove the PCM from the dash panel and move it aside. Do not disconnect the PCM harness connector.In the engine compartment, remove the heater/air conditioning housing assembly-to-chassis nuts.In the passenger-s compartment, remove the heater/air conditioning housing-to-dash panel nuts.Pull the heater/air conditioning housing assembly rearward far enough to clear the studs and air conditioning drain tube holes.Remove the heater/air conditioning housing assembly from the vehicle.Remove the upper-to-lower heater/air conditioning housing screws and remove the upper housing.Remove the heater core from the lower housing.
No it does not, it has to do with the cooling system of the engine and the heater. Refrigerant is used in the Air Conditioner.
You have to take out the whole heater and air condiasioning system out and replace the new heater core in. When you replace the heater core, you firset have to put the air condiasoning system in then the heating system/ heater core. When you take the old systems out, you first have to take out the A.C then the heater.

If its just the cord, then follow the old cord to the back side of the engine ( really the side of the engine closest to the firewall ) and replace it. When the engine is cold, plug it in and you will hear the block heater heating up. If you don't hear anything, then replace the heater also. That requires a little more knowledge.
No, they use the engine cooling system as the source of cabin heat.
No as the heater is run utilizing the fluid from your radiator and an electric fan. Using the air conditioning does as the pump is run from a belt on your engine.
