1994 Dodge Caravan Slider Door

Hello sir. It just rolls on the bottom but needs to be inserted back into the top track, why not try and remove the track runner wheels, the top one should come off the top of the door, then insert it back in the track and have someone help you to line it up so you can then get the screws started again and tighten it up. It's an old van and this should not have happened, even with extreme force. There may be a track hinge that broke so it may need to get into a body shop because if it needs any new parts they'll need to be painted. If it is too confusing buy a Dodge caravan service manual it will be more specific. You could find another one at any dealer if they have any used ones made before 1996, they were all the same before 96. Ok? Good luck.
