Some people received a letter from Ford last April 2014, telling them the Lighting Control Module, or LCM, can quit working without notice so they had extended the warranty to 15 years instead of announcing a recall. It's called "Ford Customer Satisfaction Program 14N01". I called the Ford Dealership this morning and discovered I could get in Monday first thing to have it checked out, but the part is on a three month back order so they can't fix it, and so an appointment will only waste my time. It will be free, so call a dealership. I'd put money down that that is your problem. A facebook group is trying to get Ford to order a recall at https://www.facebook.com/groups/14N01/ .
