You have vacuum operated locking hubs. Chances are they are not working. Inspect the vacuum line(s) coming from your front axle to see if there are any problems.
That's what it is for most folks when this happens. Since your light is coming on, that says there is feedback from your t-case that it has changed modes. I take it that you can get into "low range" -- but you're not getting any drive with the front wheels, yes?
Obviously check your front driveshaft as well!

I just had the same problem with my 00. Checked everything couldn't find a thing wrong.... turns out my daytime driving light module blew a fuse and therefore couldn't get the vaccuum lines going. If you wondering what daytime running lights have to do with the vaccuum lines, those lines connect up to the same module.... which is located near the front passenger wheel well on the inside. I replaced the module and everything was fine.

i did that mod where u pull those little metal clips out, it seems to have locked te driver side hub but not the passenger one.. i spin the DS wheel and both CV shafts spin but not the passenger wheel.
back to your problem, did u try putting it in reverse? i put my truck on a lift and tried 4wd, the front didnt spin in 4HI but in 4low it did and when i went back to 4 hi it did... idk, try goin between them or backing up a lil like on older trucks
