I have the same problem and have for about 1.5 years. If i pull one of the 4x4 control module fuses under the pass kick panel and put it right back in it works. I have had the shift motor and 4x4 control module replaced twice each and still have the problem. try pulling some fuses, putting them back in and trying again. (you can leave the truck on in 4hi, thats what I do)

on mine, not being able to get into 4wdLo was because of a faulty shift position sensor, mounted at the shift lever on the auto tranny. The "neutral position didn't work, the truck wouldn't start in neutral, only park, and since it never knew when it was in neutral, it would never allow 4wdLo. easy enough to test for that, with engine off shift into neutral and try to start the truck.
