Hello hopefully I can get some help and direction. I have a 2012 2500 4x4. The Traction light, abs, and service 4wd light is on and won’t allow my four wheel drive to work. A shop said these are common for the wiring that goes into the fuse box to get corrosion in it and that it needs replaced. I’m not convinced that’s it. I’ve checked grounds and replaced the rear wheel speed sensors. It used to be intermittent but now won’t work at all. Any suggestions? Thanks!
