OK. I tested for 12v at the pressure port above compressor for the aux fan. It had power. So I jumped it and fan turns on. I also jumped the dryer sensor and jumped it and no clutch engagement. I then checked for 12v at clutch connector. Nothing.

I do not see an aux fan relay. Just 30 amp fuse. Obviously its good cause fan runs. But checked it anyway and its good. Switched ac relay with starter relay and still nothing. I guess maybe its something funky with my climate control panel? What else could it be other than ground?
