It's not shifting. So, either the controller, or the shift motor is failing. I *think* you can read codes, and it will tell you what it thinks is going on. Probably need a fairly high zoot scanner to read them though. Don't know if the average parts store scanner will. Although, the scanners they use at advance here where I live, could read ABS, and SRS codes.....

Yeah, I looked up some people say the ground wire gets corroded from the salt and I live in Iowa so we salt our roads so if they cant get it I'll have to dig myself.

Well the shop couldn't figure it out and there's no 4x4 service light on. It had a broken speed sensor in the right front which I fixed then erased the codes, still no luck. Any advice on what it could be?
