Thought this was worth following up for someone else having a similar problem. J.HIDALGO was right, the wires were severed in the door column. The fact that when I got the car the door checks were broken should have been indicative of the problem but live and learn. So anyway, I have one side fixed and the other will follow soon.
Thanks for all the suggestions.
