central locking

[drpaul]

Hi all,

We now have a 2002 2.0 hdi berlingo.

The central locking doesn't work. We only have a normal key so no remote.

When you lock the driver’s door none of the other doors lock or do anything at all.

There is no noise or any clicking from anywhere.

I have had the door cards off both sides and there is only 2 wires going to each door lock. ( a green one and a green?yellow one) The wiring diagram in the Haynes manual show that there should be a few wires going to them so am confused on that.

I have checked out all the fuses and they are all fine.

Any ideas where I should look now?

Many thanks
