I see this has been asked a while back just wondering if any solutions have been thought of. Also is it possible to take the power window switch/ motor out of either and Lt2 or LTZ 2013 model and would they fit into a 2013 LT? Would reprogramming be needed of the BCM? Seems kind of odd to have only the auto down but not auto up in all models. I mean if you have one why not the other?
