If your having a problem with the door(s) latching and staying closed, you need to determine which doors you have. Does it appear that the area where the door handle mount has been altered? Look inside for welds/fabrication. The area where the vent window would go would have to have been cut out. If they have changed the later (newer) type doors, did they change out the striker plates? In most cases the door latches are just worn out, or need some special attention in order to get them working right. Have you checked the tech tips for adjusting doors? Do a search for any information you can find out about the different type doors/latches, also how to make repairs. In order to get the doors to operate properly all components have to be in order. That means good hinges, weatherstrip, latches and strikers.
