No, they use the engine cooling system as the source of cabin heat.
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.
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.
The air conditioning in your vehicle may have a couple of different problems such as : (1). your heater core may be out -- this can cost you because it usually takes time to get to the heater core. However if you have the time and patience to do you can save the money by doing it yourself. (2). no refrigerant -- you will have to check your vehicles manual for the type of refrigerant to use
No, but it will effect the heater. The only fluid that will effect the AC will be your refrigerant known as R-134a

On top of the air conditioning accumulator (can), located on the passenger side of your engine not too far from the electric fan motor for your heater core/ air conditioning evaporator. It has a plastic dust cap covering the valve.

no , the heater core is for your heat , the evaporator core is for your air conditioning ( cooling )
