All four power windows have stoped working. everything else works fine. The sunroof opens and closes all other electrical operates as normal but the windows are dead. I checked fuses and they seem to be fine and I can't find a relay that is specific to them. What could it be?

The switch in the center console may require replacement, or the relay module under the rear seat is at fault Pop up the rear seat base and look at the electronics box on the left side, it holds the relay and general modules. Tap on them and see if it helps, or remove and replace them, it may be loose solder joint on the circuit board.
