Kinda sounds like the transfer case shift motor, you can try having someone push the 4X4 button while you lightly tap on the motor, sometimes this will "shock" the motor and it will run for a couple of times, if it does run and all the lights tell you it's good to go then you will have to replace the motor soon, if it does not run then you will have to do a lot of circuit checking to make sure the signals to the control module are good and the signals and powers to and from the shift motor assembly or right, and that is a lot of circuit checking with this system.

I'll give it a try and hope that it is just the motor cause I don't really want to check all the circuits. Thank you tennisshoes!
