My taillights and brake lights don't work.
The multifunction switch has a manufacturer recall that is active on the switch since 2011. The switch may be the cause of all lights on the rear to fail. The recall ID is 11V352000, and is dated 7/13/2011. I recommend having a mechanic, such as one from YourMechanic, inspect your rear lights system to verify if this is your problem. If your vehicle is in the recall, any Ford dealer should perform the recall for free.
