door ajar light blinks on & off when driving

Hello, not sure about the door ajar lights, but if the car was jump started - and it started OK, I'm not sure how this could have caused a door ajar light to come on. However, alternatively -- it's possible that a faulty door ajar switch could be keeping the interior lights powered while the car is off -- draining the battery and preventing the car from starting as a result. I'd use a diagnostic tool to determine which door is showing "open" when the doors are closed, so you can hone in on that one and do some troubleshooting.
