electical problem on 2003 Mercedes-Benz CLK500

The control panel on the driver side door (seat, window, trunk) has stopped working. Checked the fuses but all appear good. Is there a relay or something at fault that I can replace myself?

No relay there. Those switches are plugged directly into the drivers door control module.
