Central locking

[Danny2009]

My central locking isn't working well it is but not properly, the drivers doors dead does nothing it locks with the pin or key that's it

If I push the pin down on the passengers door all the locks lock them self then unlock again straight away, the drivers door does nothing though its dead

I have checked the door looms near the hinges as they snap on 306's don't know if these are the same but both doors are fine, unscrewed the connector and Huey all have good contacts no corrosion.

I did a search and some mention door switch what's this?

It's a 51 plate berlingo multispace

I changed the box in the door with the door catch for a known good one and still no joy any ideas?

I'm not an expert on Central locking systems...
(I got some experience fitting a third-party one in a previous car)

1. Does your interior lights work correctly?
(Switch on/off when doors are opened/closed. Just in case the ystem uses those switches to detect door positions... )
2. Check for bent linkage in the doors. Bent linkages can result in not enough force being transferred. Then the doors automatically unlock again, to be in a 'safe' position.
3. The control unit may be fried.
4. One or more of the wires may be damaged.

3 and 4 will probably require you to dig into the dashboard...

Lights work fine well the front one does the 2 rear ones don't work at all think its the bulbs, the CD player also goes on and off with the doors and the front interior light fades out when the door shuts

Where's the control unit?
