So we have the compressor that compressed the refrigerant to a high pressure gas that went through the line. Now it goes through the condenser. In this condensor unit, it's like a radiator. It will take that high pressure gas and cool it down. As it cools down, it becomes liquid. That's the reason why it's called condenser. Now I'm going to talk about servicing the air conditioner unit. Obviously the vehicle does not have cool air coming out of it. We need to find out why. Usually there's two usual problems that this can happen. One that there is no more refrigerant in it or there is not enough refrigerant in it to actuate the clutch mechanisms to turn the compressor on. The other problem might be a mechanical issue. The compressor is actually broken and won't come on.
