Doors lock them immediately unlock

[Havoc99]

Help with problem please guys...
Doors lock them immediately unlock.
Door open warning sound continually on (driving me nuts !!!)
So am assuming one of the doors is not telling the ECU that it is closed.
The sliding door connectors seem ok and spring in and out ok and the actual contacts seem ok
On the drivers door the little black button near the door hinge goes in and out ok
I cannot find any similar switches on the passenger door or either of the rear barn doors ?
How can i determine which door has the problem ?
This problem suddenly happened, no warnings beforehand.

Or could it be something else and not actually be a door issue ?

Thanks in advance

Maybe a broken wire in rear door loom

Or a problem with the contacts on the SLD

Yeah mine always played up, I use to push door in with my shoulder as I pressed remote button and it would work then.

hi,
not saying this will cure it but i had this problem, turned out to be rear passenger barn door, i cleaned everything but still locked then unlocked, so i slammed the door shut with a bit more force than usual ( temper temper ! ) then when I locked it it stayed locked , so now if i don't slam the door it will lock/unlock.
as I said not saying this will work but it works for me, 2008 lwb hi roof transit, 163000mls, one fault i can't cure, cutting out when engine cold
