Maybe it has something to do with the reverse lights? I'm not sure of any electric differences between park and reverse
what ever is going on its giving power to the 4x4 light (hubs do not engage) but taking power/ground away from the window control, the controls on the door and the controls for the sunroof.
well talked to my auto instructor. were going to hook it up to the schools EVO scan tool. its like a $1500 unit. it can find opens in electrical circuits. pretty cool unit. ill let yall know what i find.
