Probably worth looking inside the rubber boot between door and door pillar anyway. Its easy enough to take it off the connector at the door pillar end.
Hi. I owe you a pint. Took boot off and noticed two broken wires, Not sure how I was able to get a kick on the meter as I had both terminals connected to socket, Any how door now locks, yippe!
