Doblo 2008/9 1.3 multijet cargo central locking
I'm new to the forum. I have and ex-Royal Mail Doblo van with a central locking problem.
The central locking works on the key fob and driver's door lock but it just locks ans immediately unlocks. There is a door open light on the dash but all the doors are properly closed. All the electric mechanisms in the doors 'clonk as if they are working.
Can anyone suggest anything please?
