Hey All,
Any ideas on what could be going on here???
I have a issue with my DRIVERS side illuminated sun visor. It just doesn't light up. Its a W124 e220 convertible.
So this is what I have done so far.
1) Changed the bulbs and I did this twice with new ones from MB dealer.
2) I used a volt meter and measured the voltage at the clip (left hand side of sun visor), where it can be pulled in/out and has two metal contacts, and I got 12V coming through.
3) Further I measured the voltage at the bulb holding points on both bulb holders, shown by a RED arrow, with both the SWITCH (blue arrow) closed and open...and this is the funny part....if I remove the bulbs I get 12V fine with the switch closed and when I measured at the same point with the bulbs in position and switch closed then I get no voltage at all...and the bulbs DON'T light up!!!
4) I also replaced the switch and the same thing as above is happening with the voltage.
Any ideas....
