Did you try switching to 4 Lo while moving?
My 2004 Dak has to be moving in neutral at about 5 mph to engage properly. Owners manual taught me that. Don't know how I'd get it into 4 Lo if I was stuck in a hole though!

How is the fluid? Should be full to the fill hole, and the right type too.
Then I would start checking the electrics. Did you drive in deep water, muck or brush?
Is the wiring harness on the t.case tight?
After that you may have to get a competent, trustworthy mechanic to look at your t.case gears, unless you trust yourself to do it.

It's reasons like this that I'm glad my 2000 has the old style shifter on the floor. That way I can just put the tranny in neutral and ram her into 4 Low.

If I were doing the job with you, I would get a manual with electrical info, so you can check for power correctly.
Turn key on to run position, not start. Turn 4WD selector knob to 4 Lo, then get under truck. Ground one end of a tester and check wiring connector prongs for power with the test probe.
I don't know what the results are supposed to be without a diagram. What I am suggesting is for you to look for power at the t.case from the dash switch and work back to the switch. Maybe there is even a relay &/or fuse under the dash or under the hood that controls the electric shifter.
If it does come to a mechanical problem inside the t.case, do not attempt to repair it unless you have a good idea what you are doing. I pulled one apart and repaired it once - out in the driveway. An expensive item to screw up.
I was fortunate. Not sure if I would do it again.
