I have an 05 yukon xl. The ac fan was intermittent thru the weekend, then yesterday it stopped. I figured the blower motor was out, no big deal. Go out this morning and hear the fan blowing before I get in the truck. The fan was blowing on high with the truck locked and no key in the ignition. I have no idea what causes this. I pulled the blower motor and it still blows constantly. I unhooked the battery for a while hoping this would reset something but it didn't. It has the digital controls for the ac/heat. Any help would be greatly appreciated. I figure it is a relay that is hung open, but I don't know which one to test, or how to test a relay either. Thanks
