This is a typical problem with these trucks and the GMC's as well. Don't
bother taking it to get looked at. They will probably tell you a bunch
of things they think is wrong with it. I did alot of internet research
on this and bought the factory manuals with the service bulletins, and
even though alot of people said it was the $400.00 to $600.00 (just
parts) switching unit at the transfer case. It took $60.00 and 20 mins.
to fix it.

The first thing i would check is the 4x4 selector switch. I know for a
fact that these will throw a service 4x4 code if they are unplugged or
shorted. They sell for 50-60$ or you may find one at a local salvage
yard for cheaper.
Taking this out and checking it only takes a few seconds, just simply
pop the switch out of the dash with the edge of your pocket knife.
After you get it out theres a few more tabs surrounding the back plate,
and this is where the circuit board is located. I would inspect it
visually to make sure nothing looks corroded and also take a sniff of it
to insure there isn't a burnt smell.
If it were the 4x4 actuator the lights would still illuminate on the
selector switch, it just wouldn't engage the 4x4. This is a typical problem with these trucks and the GMC's as well. Don't bother taking it to get looked at.
