Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Since the 3rd brake light works this means we need to work at the multifunction switch sticking out the left side of the steering column. Test the light green wire there. If it is powered when braking then the multifunction switch is bad. If there is no voltage there then there is a wire break between the multifunction switch and the brake switch.
