E320 Cdi 2003 no power in window switches

[sachkhund]

Hello Folks, does anyone know what wrong with my window switches, there is no power in all the window switches except the front passenger side.

I have checked all the fuses and they seem to be ok. Also the interior curtesy lights do not come on when any of the 4 door are opened.

Any input will be appreciated.

I would have thought that a broken wire where the door opens could well be the fault, only by removing the door cards and checking the voltages will you know.
