First, check the 4wd fuse to make sure it is good. In addition to just checking the fuse, make sure there is power to it. If that is good, there is a black wire coming from the actuator on the axle. Make sure it has continuity to ground.
I attached a pic below of the fuse and a portion of the wiring schematic. Here is a link you may find helpful when testing for power at the fuse:
Let me know. Also, if the fuse is good, I need to know if the 4wd light is turning on and if there is power to the actuator.
