Hey all, hoping someone has some insight for me to get 4x4 back on my truck. 2006 2500 - I've had the intermittent brake and ABS light issue for a few months but didn't care until I found that I can't engage 4WD when the warning lights are on. When the brake & ABS lights are off, 4WD works fine - with warning lights, the 4WD indicator simply flashes maddeningly at me.

I have a new front wheel ABS sensor - tried it on both wheels but the light was still there. Haven't replaced the rear diff sensor but the wires all look okay.

Any ideas how I can get 4WD even if my ABS isn't working? I don't need ABS but when this current warm weather disappears I will need 4x4 again.

Thanks!!
