Hello. It seems there is something wrong with my airconditioner on my 1998 200sx se-r. I posted on another section, but I have a new question: If I turn on the AC button and turn on the fan, should I notice or hear the compressor going even if I am out of refrigerant? I had thought that I was out of refrigerant, but now I noticed that even when I turn the AC on, the car seems to have no reaction to the AC. Any ideas on how I can check to see if it is something other than the refrigerant.
