Seeing as the central locking works from both interior rockers (in both directions?) I would suggest you check the linkage in the passenger door, and that when you work the lock by the key, the linkage doesn't flex preventing the electrical slider thingy (sorry - dunno what to call it!) from making contact. It sounds like this slider is loose in the pass door. It would also account for the continuous clicking (NB this is the lock module, but is NOT what happenns when this goes wrong) It sounds like your lock module might need attention anyway (hey, if it's original, they all do!)
