Air conditioner

The one closest to your AC compressor... i.e. the part that the belt spins around.. Is the low side.. Not to mention, air conditioning recharge hoses ONLY FIT on the low side.. Worst case scenario, try both.. the one that it clamps down on to is the low side..

I have a 1998 dodge neon 2.0 L DOHC I have an a/c problem. It is blowing warm air. Before I try to fill it I find the pressure on the system is already in the red zone as in far too high. I have emptied the a/c unit and there was some refridgerant in it. But when I went to fill it up again the gauge immediately ran back up close to the red zone as I was partially emptying the referidgerant back into the system. I have the a/c running when I am doing it? Is that correct? I was told that an orfus tube could be one of the problems as it may be blocked probably by someone putting a sealant from the past? If so I called the dealership and they could only tell me there are 3 tubes and do not know which one I am talking about? Also my car has 2 black caps and no blue cap how do I know where to fill it? I see the hose line only fits on the one valve which is the one on the line and not on the container. Can anyone give me some ideas. Thanks. Gerry glongpre1@cogeco.ca

Problem is this. Your system is R12 and you are looking for the port for 134a refrigerant. The low side port for the Fiero system for charging is in the front on the accumulator/drier (sliver can).

The AC low pressure service port on the 1998 olds cutless is located next to the firewall behind the left side of the engine.
