Headlights would not turn on, stranding me overnight. Headlights non-operational when set to auto, manual, or high beams. All other lights worked fine (parking lights, interior lights, brake lights). Took car in to Ford dealership for diagnostic. They found a non-operational lighting control module (lcm). I approved replacement with new Ford lcm (part # 5w7z-13c788-ac). The repair bill was $860. 22 + sales tax ($577. 72 for the part, $282. 50 for labor).
Rear brake lights with light to moderate braking when starting to push brake pedal the rear lights come on. When you reach a point that you ease up on the pedal pressure, (even so slight that you don't feel the pedal move), the brake lights go off. The vehicle is actually still braking. If you proceed to apply pressure again the brake lights come back on and once again as soon as you ease up on pedal pressure the lights go off. I found myself sitting at stop signs, red lights, even in the middle of the road waiting to turn left with my foot on the brake, but no rear brake lights on. A new brake light switch was installed for 150 bucks with no change.
