Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
Most likely cause of this problem is a faulty brake pedal switch, it could also be out of adjustment. Check the bulbs first. If the 3rd brake like works then it is not the switch.
