Hello, I have a 2013 Transit connect that has a few issues. It's in great shape, only 66,xxx miles at the time of posting, however I am having a few issues with it. The main issue is that the door ajar light stays on most of the time even though all doors are closed, which causes the doors to stay unlocked and not be able to be locked. I have narrowed it down to the rear barn doors, I believe some kind of sensor is faulty in them. If I do want the doors to lock I have to keep opening and closing the rear doors until by chance the sensor acknowledges the doors are closed, allowing me to lock it. I do a lot of hauling and park in areas with a lot of homeless, so not being able to secure my cargo safely when I'm not around is a big problem for me. Where is this sensor located? How would I go about repairing it? I would like to do it myself if it's possible.
