My passenger side headlight is out and the Lamp Out light is on in my dashboard. I changed bulb and no luck. I couldn't find any fuses or relays for headlight lamps in fuse box. Everything else, fog lights, tail lights , but no headlight fuses/relays. Highbeams will come on in the same bulb but not the headlights. Any ideas appreciated. thx

Might be a fusebox issue. You might try unhooking the battery for about 30 min just to see if it helps.

 

No luck. I hope it ain't defective FCM.

 

Thanks for the replies. I bought one of those probe testers this morning. I
removed bulb and 1st used electrical contact cleaner to clean the contacts
just in case. I tested the sockets. The high beam one gets power but the low
beam nada. There's one ground wire for both I believe so I assume bad ground
would affect both?
Seems there's no fuse or relay for this light and it gets it's marching orders from
FCM from what I understand reading the service manual.
If it's the FCM that's defective I'll have to figure out a way to hard wire the light.
No way I'm dishing out a grand or so for one defective low-beam.

just trace the low beam wire with a tester, chances are its rubbed through and shorting out or somthing, then just replace that strand.

 

Thanks for the help guys! I went to the dealer today and they were clueless. I checked the wire schematics and traced the harness (C7) which attaches to fuse box. I disconnected and sprayed with contact cleaner again. I also pulled off the FCM and sprayed the hell out of that 49 pin PCI bus thingie.
That did the trick, lamp out light gone and low beam working. Gottah love the internet.
