I've not had the door panel off yet - that's for the weekend. Haynes book shows the wiring digram and it looks like the LH and RH switches get power from the same connection so the driver window switch is likely getting power. The driver door then has the control unit (for one touch) and a timer/relay. I think the problem must be with either of these or a connection to them but where are they located?
The fuse box has this missing space for something above the green relay - anyone know what it is?

It could be the window motor was disconnected due to broken regulator cable but need to find that out.
Thanks in advance!
