I have had many MB's in the past and have always been able to fix or troubleshoot any issue I've had with them but the Birthday gift to myself( 2004 MB CLK500 convertible) has me stumped. I have no low beams, have done the easy stuff replaced bulbs,checked fuses ect. And am still baffled. Any suggestions ? I'm wanting to put new wiring harnesses on both light assemblies but not before I do a little more research.
