Re: of the top of your head... 4v A/C and 2v A/C

did you ever get the recall done on the 96? if you did, then they are the exact same and you should be able to reuse the 96 items. if the recall was never done, then they are different (the condenser is different) and i would suggest you upgrade to the revised style so your car doesnt run too hot when the A/C is on.
Here's your answer, he is correct, there is no difference. They interchange
Now, for A/C 101, I will be your teacher. The way A/C works is like this, ever sit a cold pop can down outside on a hot summer day? You notice the water drops forming on it? And what happens to your pop? It gets warm. The reason it gets warm is because of the condensation that forms on the outside of the can, but more on that later.
The next thing is have you spilled something outside on a hot day? Like a pop, beer or water? It evaporates right? disappears, from the liquid heating up and turning to water vapor in the air, kind of like a kettle of boiling water puts off steam that disappears and fills the house with water vapor that condenses on any cool, usually glass, surface?
Ok, now we have our two terms, evaporation and condensation, when something evaporates, it takes heat or energy(the hot concrete, sun, etc.) to make it go from a liquid form into a gas. Well, when it goes from a vapor back into a liquid, it has to release that heat right? Thats the reason a cold surface like a pop can or window glass gets that water or fog on it. So when something evaporates, it needs to absorb heat from it's surroundings, and it absorbs this heat until it reaches its energy peak for evaporation, at which time it turns from liquid into a gas, or vapor. When it condences and goes from a gas, or vapor back into a liquid, it gives off that heat, so it has to give off or release that heat, usually onto a cool or cold surface, so that's why your pop gets warm. Thats the purpose of a can cuzzi, it wraps the can and keeps the water from condensing on it and releasing its heat of evaporation into the pop.
So we have our two terms defined, evaporation and condensation, one absorbs heat, one releases or gives off heat. So in an a/c system, you want the hot air inside the car turned into cool air, and that heat taken out of the inside of the passenger compartment and moved outside. how do we accomplish this? Well, when something evaporates it needs to absorb heat from it's surroundings, so what better source than the hot air inside your car? And when it condenses, it has to give off that heat right? So what better place than a radiator right out in front of the fan stuck into the airflow coming from the grille of the car.
The compressor compresses the refrigerant gas. We use a gas because gasses quickly evapoarte when they have been turned into a liquid, kind of like the liquid air things people use to spray off their computers. So the compressor pumps and compresses the gas into a high pressure, very hot gas. That is pushed through the system by the compressor continually putting out more compressed gas, we'll get to where it comes from in a minute. But as it comes out into the small lines as a high pressure gas, it goes into the condensor, (get it? the name says what it does) where that high pressure gas gets condensed(by giving off its energy(heat) of evaporation) and turns into a high pressure liquid. This then leaves the condensor in another small pipe or hose, and travels towards the firewall, and into the evaporator(guess what happens in it?). Now there's one more thing inline before it reaches the evaporator, and that is some form of restriction, usually an orifice tube, a tube sealed into the larger tube, that goes down to a tiny hole, so that only a small amount of the high pressure liquid makes it through. Kind of like filling your mouth with water and puckering your lips as you spray out a fine mist of liquid, this allows it to evaporate very quickly and cool down it's surroundings fast. It also serves another purpose, that is to seperate the high pressure from the low pressure inside the evaporator. As this sprays into the evaporator, the liquid starts to draw the heat from the coils of the evaporator and as it sucks this heat out it makes the evaporator surface get very very cold, so as the hot air comes in, it drops off it's energy(heat) and exits as nice cool air. As the liquid evaporates it becomes a low pressure gas, and the compressor sucks it into itself through the large hoses, after it has been drawn through the receiver drier to eliminate any moisture that could freeze up and cause problems inside the system.
Hope that helps.
