I have a Sierra 1500 4wd and it don't work when u push the 4 hi or low button or the anytime 4wd. It does not engage when the vehicle is on there is no lights on the switch but when the vehicle is turned on the switch will light up and then turn off. It doesn't even tell u if it's in 2 wheel drive there is also a message on the consul saying service 4 wheel drive. I check all fuse and there okay, it drives and it is in 2 wheel drive how I know is it snowed here a couple weeks ago and I tried to put it in 4wd but got stuck and the only thing spinning was the rear wheels.
have the same problem?
