I just bought a 04 about three monthes ago. The 4x4 worked fine at the time. This evening it did not work at all........I would put in into 4x4 ( high and low ) and it would not work at all. All I did was spin my back tires. This really sucks becuase it is really cold and there is 10 inches of snow on the ground right now. I'm new to this truck and wondering if anybody has any ideas where to get started trying to figure out the problem........Does this style truck have trouble going into 4x4 if the truck has been out in the cold for a while? Looking for some help.............Thanks
