Your transfer case has a switch on it. There is a brown wire and a light blue wire on this switch. Make sure this switch is good. The lt. Blue wire activates the front axle solenoid -- it also activates the transfer case relay. Make sure this wire is good. The brown wire goes to the front axle switch and the convenience center. Make sure the front axle switch is good.
If you jump out this switch it may be easier to determine if the transfer case switch itself is bad.
