I doubt this will work, but my 03 Sierra, which had the same electro-transfer case shifter thingy, twice would not shift out of 2WD-Hi into 4WD-Hi (light would flicker and nothing would happen). I realize this is different than your situation because it did what it said (not shift), but just in case: I simply disconnected the battery for a few seconds and reconnected it. Then, bingo, it would work fine for nine months or so.
