Here's what I can suggest:
1. Safety First: Before attempting any repairs, ensure your van is safely parked on a level surface with the parking brake engaged.
2. Identify the Problem:
* Track Issues: Inspect the track that the door slides on. Look for debris, rust, or damage.
* Roller Problems: Check the rollers on the door. They may be worn, damaged, or jammed.
* Latch Issues: Examine the latch mechanism and its components. It might be stuck, broken, or misaligned.
* Other Components: Check door seals, handles, and any other moving parts that could be contributing to the jam.
3. Seek Professional Help:
* Mechanic: A qualified mechanic can diagnose the problem and provide the correct repair solution.
* Ford Dealership: They have specialized knowledge of your vehicle and can access repair manuals and parts.
4. DIY Solutions:
* Lubrication: If the problem is minor, try lubricating the track and rollers with a silicone-based spray lubricant. This can help to loosen up any friction.
* Manual Release: Some sliding doors have a manual release mechanism located near the latch. If you can find it, try using it to release the door.
* Removing the Door: If the door is completely jammed, you might have to remove it for repairs. This is a more advanced procedure and is best left to a professional.
Important:
* Avoid forcing the door open, as this can cause further damage.
* Always consult your owner's manual for specific information about your vehicle.
* Safety should always be your top priority.
Remember, safety is paramount. If you're not comfortable tackling this repair yourself, don't hesitate to seek professional help.
