I have just bought a 2003 Expedition, and noticed that when i open any door the courtesy lights doesn’t turn on as well as the door ajar message doesn’t show. I think is difficult that every door sensor is broken and I suppose that the former owner did some bypassing/disconnecting to save money instead of buying a new sensor. Could you help me solving it? Thanks in advance. The manual switch works and when I close the doors the lights work as well.
