Maybe I don't understand what you mean....but from your description, it sounds like it's functioning normal. The AC compressor will kick in/out based on what the system computer wants.

Are you saying the AC doesn't work?....

There should be a pressure switch for the AC system.. Maybe that is faulty and causing the system to think that there is not enough Freon pressure. That switch is what allows the compressor to kick on when the computer tells it to..

Should be easy to replace and fairly inespensive. I believe there is a valve under the switch, so you can unscrew it without losing any freon..

Hope that helps

oh, normally the switch has 2 wires coming in and it usually attaches directly to the AC lines or maybe the compressor itself..

with mbehlok. The pressure switch could be the issue if the system is charged correctly.
