Yep.
The relay coils/switches are inside the controller box.

Can anybody point to me where the battery power to the control box comes from. I can't make heads nor tails from the diagrams.

Power through fuse 31 of the CE panel a Red/Black line goes to pin 7 on what looks like harness III on the control box. Pin 5 of what looks like harness I is a Brown/White which means it is a switched ground and this goes to the Interior Light Relay. The Wiring Diagram online is a little fuzzy to view. Google the 'ligeti 928' and the lines are on Sheet 3 of the Wiring Diagrams.

Add: Here's a link to a primer that will help you interpret the Wiring Diagrams.

Ok, some success. Found the alarm had a relay for same reason connected to K24 of the CE. I've replaced the relay and now the windows work, sunroof doesn't and engine fans run. I am thinking that the other side of the relay is connected incorrectly. The wire runs behind the CE panel so I'll have to pull the CE panel forward and see what's going on.

And thanks to Alan for the primer. It helped out big time.
