Ford transit connect side door will lock but not unlock. The recall covers nearly 2 2. The side door is double locked and wont open. 2011 transit connect will not allow me to lock the doors anymore. Connect the other end.
Cheers for the advice. Interior lights and door ajar light required extra slamming of drivers door to go out for several weeks. Video about how you can open stuck sliding door on ford transit mk6 van. Now will not respond to even a hard door slam and vehicle with 8 000 in stock and parts is not lockable.
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. 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. Sometimes when you press the unlock button on the keyfob to unlock the rear of the van only the back doors 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.
I ve got a 51 plate t260. 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. 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.
