1st of all, check the "4wd" and "t case" fuses in the panel left side of intsrument panel. 2nd, turn the key to run, not start, and see if all the lights blink a couple of times. 3rd, the t case will only accept a shift if the engine is running and tranny is in neutral. If any of these don't work, you'll need a scan tool to get codes for repair. As far as worrying about it, if you select something and the light doesn't come on, it's not shifting to what you selected!!............Steve
