Headlight Switch Not Working, I don't think it's receiving power
I wonder if you worked out what was wrong with your light conundrum.
I am having the same with mine 🤣 lights stay on regardless night / day, the switch itself doesn't respond to any input and not lighted up whatsoever.




What happens if you just unplug the clock? Not suggesting a fix but interested in failure mode.

But, there is a way to make the switch do what it should do in the "0" position.....disable the DRL. This will make the light switch do what the markings around it tell, it just is that with this you do not haver DRLs.
Wonder if these clock changers checked that their DRLs are still enabled after tinkering with wiring and such so that the DRLs did not get disabled somehow and the switch started working like it should?
I really don't have need to turn the head lights OFF but if I need this I will just disable the DRLs and turn the switch to "0".
I don't think this is a switch problem as both of my cars behave exactly the same. It must be programming issue that MB never fixed.
