Thanks for the post and pics. I am having AC issues too but slightly different, my model is 2007 4.8i N62T. My AC is running but my AUX FAN in the front of the SAV keeps running when AC is on. My Indy diagnose it as Bad Solar sensor in the rear mirror, he said it even through the codes. If I do it myself and replace it then wondering how to reset the codes if needed. Plus i still dont understand how a solar sensor can control the FAN infront of the Radiator...part # 61359214977
