No power on most systems

[koenux]

Hi there,

I've got a problem with my car. Most systems won't work.
Systems that do work are: starting engine, headlights, interiorlights, alarm, horn
Systems that don't work are: wipers, meters (like speed) (digital), radio/cigarette, traffic indicaters. heating fans, etc

So I aleady checked all the fuses I could find and they are ok.

Does anyone know what the problem might be?

Thanks!
