Power locks and windows on 2001 Mercedes-Benz E55 AMG

What causes the power locks and windows not to work? I have checked all fuses that I can find and none of them appear blown.

Electrical problems like this can be due to many things, and unless someone has some experience with this problem on this vehicle, it will require a diagnosis by a repair shop. It may be a switch, relay or a wiring problem, or even a software problem.
