Have you checked the fuses?
Check all fuses,and check the 4x4 relays, if you find no problems then you can check the switch to make sure it is working, and then i would have to say the 4x4 shift motor, you can actually remove the motor from the transfer case and try putting it in 4x4, if the motor moves and the light comes on the problem is internal in the transfer case(unlikely but can happen)

what year is the vehicle? it could be the switch but it could also be the shift motor on the transfer case.or the wiring in between.
