Alright, so winter is here, and KC hasn't had any real snow yet, but I'm sure it is around the corner. Last year my 4wd did not work at all do to a faulty shift actuator. Replace the shift actuator and it shifts into 4wd hi just fine. Wouldn't switch into 4wd lo so I replaced the switch on the dash (Murdog mentioned this was a common piece to go bad.) Unfortunately it still does nothing when I press the 4wd lo button. Any one got any suggestions on where to start diagnosing this problem before I need to go over the river and through the woods through the snow for Christmas?
