transfer case wiring

billum · February 16, 2020

I have a weird problem with my transfer case wiring apparently. I couldn't get my transfer case motor back on and I had no lights on at the selector buttons. So i took my fuse panel apart and flipped it over and was looking at the underneath. Didn't really see anything wrong and left it flipped up. I turned the key on with the t-case motor plugged in and heard it working. So I got under and the motor went right on without any problem at all. So I thought ah ha got it and put it all back together. Guess what now my lights are off again and nothing works again and both fuses are good SOOOOOO?. What the heck do I do now other than drag it out into the yard and torch it because this has been a nightmare of a problem from the start. Everything has been replaced because this said it was that and so on. I am truly ready to burn this P.O.S. HELP. 2000 Chevy Silverado.

Sounds like a wiring problem around the fuse panel, one or more wires has failed/rubbed through or the connector isn't good anymore. The movement of the fusebox got it working again, but reinstalling it returned the problem.
