Why is my door ajar sensor/alarm going off when all my doors are closed?

What is your question?

Why is my dome light coming on and my door ajar message coming on and the door alarm going off and it flashes on off even while driving? nothing makes it stop until turn off engine or it stops on its own, I looked for short in the wires in door and followed all the way to engine, non found looked for sensor can’t find one or relay switch

What makes this problem better or worse?

Does it more in freezing temp but still does it in summer just a bit less
