To start, I am showing two fuses. They are numbers 2 and 24. Two is for the transfer case and 24 is the for the 4wd. There is a transfer case switch at the top left of the transfer case and a transfer case encoder on the right side of the transfer case. Have you checked wiring to these items and the fuses?
From the transfer case switch in the vehicle, there is a gry/blk (for 4wd hi) wire that goes from the switch to the transfer case control module which is under the dash. Check if you can find it and see if there is power to it.
As far s the relay, it looks like I was wrong.
