Hi folks,
My girlfriend's W168 A-class has developed a headlamp fault. The left-hand headlamp has no main beam.
High beam works on both left and right. Sidelights work on left and right. Main beam works only on right.
The fuse (number "1") under the panel by the door is good, and the bulb is good. I can measure 12v at the top terminal of fuse 1 when I switch the main lights on. I cannot measure any voltage at the appropriate terminal on the bulb holder.
Any ideas please? Are there any troublesome connectors between these two points? Or common failure points? The wiring is basically completely inaccessible in this car so I'm dreading having an awkward problem.
Thanks!
