Hello and thanks for looking at my post. I currently have a 06 XK/Commander that will not blow air from the front blower system consistently. I replaced the resister with another and pig tail due to the two parts being fused together, still no luck. Replaced the blower motor, and temp control switch, still nothing. Due to seeing that the wiring harness looked to be a little cooked from the multiple issues I went ahead and replaced it, pretty big pain in the you know what. And to my dismay I still have nothing. Now I'm at the point where I feel I've exhausted my options and wanted to see if there's something I missed. The 40AMP fuse looks to be good, even swapped with another known working one, no love. Due to me having the old fan I connected it and watched it as I turned over the ignition, I do see a faint movement but it just doesn't go, even when I help it to see if it's possibly the bad bearing holding it back I get nothing. The main connector to the harness looks fine as well, also sometimes out of nowhere prior to replacing the harness my blower would just kick on, and work, that's until I have to turn off the ignition than I'm back to the craps shoot of, "Is my air going to work today...??? Any help is appreciated, thanks again.....

Have you check the control head that houses the switch? If its the simpler single zone system, you can put it into a selft test. If its the more sophisticated dual zone, automatic temp control, only the Dealer tool can start the self test. I have a 2010, it may have been different in the 2006.
