Can anyone help me with my AC issue. I have a 2004 G35 RWD Sedan and the AC went out one day and never blew cold air again. I have played with all the controls and they all work but no cold air. I have recharged the AC feron and changed all the fuses but the AC will not turn on. The AC Compressor kicks on when I add a separate power source directly to it but only when there is a separate power attached. I came to the conclusion that the relay was not working properly but I am having issues locating it. From what I have read the AC Relay is incorporated into the IDPM which is located next to the battery. If this is true can I replace the IDPM box and will that fix my problem? There are no other issues with my vehicle, its does not over heat, and I have already replace the Radio Finisher. This is clearly a AC issue only and I don't want to spend a lot on money at a shop for something I can myself.
