Which transfer case?
Auto or std transmission?
Double check all fuses.
Is the front axle locking in or getting 12 volt power to actuator?
How is the wiring to front axle actuator?

Check to see if you are getting 12v to the blue wire when you put the shift lever in 4wd.

It might be the 4x4 That in the front axle, that is what went out in my 94 and i was stranded for around 2 1/2hrs befor anyone really came around the area so have that looked at.
