Loose sliding door on Plymouth voyager? need help adjusting door or sensors?

2000 Plymouth Voyager. The problem appeared rarely at first but now happens all the darn time. While driving the interior lights will come on and off. at the same time all the electric locks try to re-lock and the 'Door Ajar' light blinks on and off. I have figured that the problem is in the right side sliding door. the door feels as if it is closing correctly. This particular door has been subjected to many "tempermental high speed closures" so it may be the sensor package has just been banged out of whack. I am hoping to find a resource to find out how to adjust the door or the door sensors. I appreciate the help
