I have a 2007 f350 6.0l 4wd crew cab single rear wheel and the Brake light on the dash as well as the 4 wheel hi and low light come on at random times and will stay on for sometimes an hour at a time along with an awful buzzer sound.
any other ideas? Would low brake fluid cause the 4 wd and 4low light to come on as well. I have the truck at the local dealer they cant fix because some reason wont do it for them. At time it Brake 4 wheel and 4 lo come and the buzzer will go for hours. The truck still runs fine except odometer goes out and cruse control wont work when this is happening. Please any help out there
