Unattached it and discovered that the contacts have acquired a lovely azure hue. Sprayed the hell out of it with switch cleaner and now even the central locking has come back to life. Although it locks then immediately unlocks, but I'll ask about that on a separate post. Thanks, appreciate the help!
I think I would be looking at what goes on under that flexible cable cover to see it there is damage there and some shorting. I know that it can cause a multitude of strange events. I was faced with this causing the doors to suddenly lock me out. I took the locking fuse out pending fixing that one or it could be embarassing if the keys were still inside the car. Azure means blue and that means heat and sparking which suggests shortcircuiting and that could also show in the wiring too with melted insulation. It could also just be dirty contacts so you need to do some physical cleaning as far as you can in that plug and socket. That pic seems to show corrossion however and you should try to get rid of the salts. If it is copper sulphate or copper hydroxide from salt reactions you could try dissolving them with boiling water( Disconnect battery) as both will dissolve. You do need that firm metal to metal contact.
If it can break it will. Matter over mind will fix it.
