Ford Transit Connect Side Door Will Lock But Not Unlock

When you then try to lock the van by pressing the lock button it relocks the rear doors and beeps the horn to say a door not closed.
Ford transit connect side door will lock but not unlock. Cheers for all your help and advice i now think i will replace the lock while the door still opens and closes it will make the job. Now will not respond to even a hard door slam and vehicle with 8 000 in stock and parts is not lockable. Removed mechanism and fitted new mechanism to side door still wont lock have you any advice wiring seems ok. The side door stays locked.
One last ditch attempt yesterday saw me applying pressure clockwise to the lock unlock knob on the inside and a mate opening and closting the handle on the outside and after a couple of minutes click it went in and now the side door opens. Hi i have a ford transit lwb 2009 the problem is the side door will not lock with central locking key fob but front and rear tail doors do so was advise that the side door locking mechanism at fault. All doors are closed though. Video about how you can open stuck sliding door on ford transit mk6 van.
Ford has issued another recall for faulty door latches which can fail to secure a door leading to its possibly coming open while the vehicle is being driven. Connect the other end. Fuse is ok i ve disconnected the wires and connected locking mech directly to same wires to bypass the contact plate on the door i ve tried swapping red white with red black then double locking door to see if this opens it. Cheers for the advice.
The side door is double locked and wont open. The recall covers nearly 2 2. Open your fuse box there is a post three marked with a symbol for the lid you will need to connect the hot side of a jumper cable to it and the ground to the door striker. 2011 transit connect will not allow me to lock the doors anymore.
