I hope that this is not considered off topic.

My right litronic headlamp is not working. I pulled the unit and checked the light. It doesn't look at all like it is blown. All of the other lights in the headlamp work fine. Fuse is fine. Does anyone have experience with this problem? My dealer tells me that 99.9% of the time, it is not the bulb. It is something else like one of the relays.

I'm looking for some help or a schematic so that I can chase this thing. Please help.

No techies out there willing to give a fellow member a little insight? C'mon guys?! My P-car dealer is making me wait until Thursday to see the car. Doesn't anyone out there have a schematic? Am I going to have to go to Pete's board?

 

I'm not sure if you have been helped yet. Number 9 and 12 are control units, there are one per side. Maybe try swaping them, then you can see if it's the control unit. Let me know, thanks!

 

Silly question... can you remove your left light assembly and plug it into your right wiring harness (not sure if it's the same plug, cant see why it wouldn't be). That way you could isolate the problem to light housing (right) or wiring/relay (electrical).

 

Thanks guys, these are the types of suggestions I was looking for. Thanks.
It looks like 12 is behind the headlamp and 9 is under the dash?? Is 9 one of the relays under the dash? Any number indicator that I should be looking for for the two controllers? Again, thanks for all the help.
