I no this topic has been OVER DONE

I have a S-reg phase 2, 5 door, 306 LXDT and the door locks unlock when i try to lock them.

I have been through almost all the threads on this forum about central locking, and non of them are any help.

1.
I have looked for my central locking control unit and it is not under the rear passenger seat, nor is it under the center console. can anyone help with this ?

2.
I have checked all the Door looms and plugs and all are fine. is there a way of testing to see which door is causing the problem

Thanks

Try using the key to lock the doors rather than the remote and try both doors (although I have to say I have no idea whether the passenger side door lock operates the central locking).

If that doesn't work, lock each door in turn from inside first and try again. If it works with one of the doors locked first then you've found your problem door.

Perhaps if you described the problem a bit more clearly - i.e. does it do this on the remote and the key? How have you checked the loom etc?

So even if you lock it with the key then does that lock stay down or pop up again?

My guess would be a changover switch on one of the front doors is not working. This would give rise to what you describe.

But if you want to try the control unit first. try looking under drivers seat.

I'd check your wiring loom in the drivers door - this is likely to be the cause of this problem.
