For those of you who haven't followed my struggle with intermittent central locking on front passenger side,I thought you may find this useful.  If you haven't had issues with the multiplugs and modules in your doors you may wish to employ this as a preventative measure.  This is for the passenger side front, I did exactly the same to the drivers door yesterday.   Anyway, we'll start with a skim through of door panel removal.   Prize apart the door handle, can be pretty well stuck together,
