Bollocks, it's proper pissing down now, so I've had to hold off right before I worked out how to get the panel off that hold the window regulator in place. I think, lower the window until I see two torx bolts through the rubber holes, then tape the window up to the door and undo the bolts.
All in all, looks pretty easy. So if my soldering fix doesn't work, then I can get a new module and fit it in the week.
