Thanks in advance for the help - my blower motor resistor is bad. It's my understanding that the new resistors require a new wiring harness. My question is this - if the one that was given to me is correct, how do I hook up the new harness which has 7 wires to the 3 wire clip that's disconnected from the old resistor? I may have the wrong part but was trying to figure it out since I'm not mechanically inclined but figured this was an easy DIY fix. My avalanche has auto air, not the ***** if that is pertinent. Thanks in advance!
