When you push the 4 hi or 4 lo button do they flash? I have a 97 jimmy that did this, I was told to disconnect the battery for an hour and then try it. I thought they were crazy but it worked. Good Luck!

That's easier said than done. First there are 2 different transfer cases, one with automatic 4wd and one without. Then DTC's need to be retrieved (if any). The automatic transfer case needs a GM scan tool to get the codes.
