I just wanted to post this for every Z owner that have a/c not working. I did everything to trouble shooting why my a/c was not working. After I found that when I jumped the compressor relay and the compressor kick on my next move was to replace the ECU. And I was right.When I replaced the ECU and turn the a c on the compressor came on. The reason is the ECU provide ground, for some reason my ECU was not doing that. Maybe I shorted some of the circuit in the ECU when i was hooking up the elecitric fans. The ECU components are very delicate so be carefull whenever you are hooking wire to get a 12 volt power source.
