Hi guys, I'm the owner of a 2002 c215 cl500 (of course right?) Since I've own this car for over a year the hazard switch panel, ABC sport, rear shade, pdc etc. Never worked, I've went and bought another panel assuming that was the culprit since I can't ever seem to locate the mysterious 4th fuse panel. And it's only two plugs that's connected to the back of the unit even tho it seems like it should be 3. Do anyone have experience in this situation and can guide me, cause when I'm tryna figure it out I look like I'm a extra in the birdbox.
