My high beams are not working on my 2003 c240 wagon. It is a new issue that just started a few days ago. I looked for a blown fuse but the diagram says there is no fuse, its electronic. The bulbs are good and I have replaced the turn signal/high beams/ wiper switch. I am at a loss. Can somebody direct me the right way to proceed with this?

 

I would have the codes read off the DTC, it'll give you a specific place to start troubleshooting.
