I hope its ok to ask a question like this here...but I have a 2012 traverse with an AC issue. The ac will works ice-cold great as long as I am moving, but if I sit still for more than a couple minutes, the air gets warm. I dug into it a little bit and discovered that one of my cooling fans doesn't work. There are two electric fans on the radiator and if my research is correct, one fan is controlled by the coolant temperature and the other is supposed to come on when the ac compressor in engaged. The one that is supposed to come on with my ac is the one not working. I used my multimeter to see if I am getting power to the terminal that plugs into that fan and it seems that I am not getting power there. I replaced the fan relays and fuses in the fuse box and it didn't fix it. Is there a switch, sensor, or anything besides a signal straight from the ECM that would tell this fan to kick on? I can't figure it out and its driving me crazy.
