lost all gears and park
Lost all gears and park. It will start in any gear but not move. The story I was given is he lost all gears while wheeling. I’m new to blazers transfer cases. I didn’t see a neutral option. I haven’t done anything yet. Any help?

Probably trying to get it into 4WD Lo
Do any of the indicators in the 4wd buttons light up or flash when you turn the key on? If not, check the ATC fuse in the underhood relay center. If fuse is blown, then figure the encoder motor is bad, and/or terminals on the plug to the TCCM are corroded.
This is the quick and dirty diagnosis that is usually correct. Only way to know for sure is to hook up a capable scanner, Sometimes bad encoder motors take out the TCCM, but not that often.
