My 2014 F-150 stopped illuminating the P for the park indicator. Also the dash lights would remain on with a pale white even after i shut down the engine and locked the truck. The next morning my battery would be dead! I called the local Ford dealership service department and they said it was my shifting control module that was bad and it needed to be replaced? Does this mean if I replace the shifting lever assembly that it would fix it or is there some other part I need to replace? Thanks Mo.
