The interior lights on this vehicle are controlled by the BCM, which could have an internal short, but it could also be a break in a wire that tells the BCM that one of the doors is open and commands the lights on.
Do the lights stay on while you are driving also? Do you get a door ajar light with it?
Both items are controlled by the BCM body control module. This model has a tendency to burn up the BCM because of it's location. It is right behind the driver side kick panel to the left of your feet when you are driving. The hood release cable runs through there and somehow water tends to get in a leak on the BCM causing internal circuitry damage. There is no way to fix it other than replace the BCM. You could replace it yourself, but you would have to get it towed to a shop with a ford programming tool to have it programmed before it will run.
The BCM is about a $500 part but it only takes a half hour to replace, so the cost would be very little labor.
