Windows and Roof Not Working

[mivu1993]

Hi! I purchase a 206cc several days ago. Everything worked fine until yesturday, all the windows and roof stopped worked at all.
The is NO sound warning and NO visual warning on dashboard, also the fuse under the dash 30Amp fuse it's fine.
Everything else working fine on the car.
It's clear for me that this is an electrical problem.
I searched a similar topic but i didn't found nothing.
What do i need to check next? Thanks!

The Roof ECU in the boot, behind the trim along the front wall. Make sure the plug is well-seated in the socket.
