I'm wondering if anyone can help with a peculiar central locking problem I've got. 1.8 Mondeo Zetec (2000) 5 door. The front passenger door central locking has stopped working. If the door is manually locked then it activates the locking on all the other doors. However it won't lock with the remote and needs to be locked seperately with the key.
Has anybody any ideas about what's gone wrong?
Thanks
