I tried that but no go no movement or hint of a noise from the window/door. Only the double-click from the relay in the right-hand side footwell.

I am presuming that the window knows it has reached the top and bottom of its travel by sensing current- current rises indicating the motor has come up against resistance and the power is cut. So I think the relay noise is it sensing too much current (maybe from a short- damaged or wet/corroded wiring.)
