NB headlight out -- bulb is OK
The left headlight is out on my NB, but the bulb is OK. Any clues on
where else to look? Are the L/R headlights fused separately? -- Grant Edwards grant.b.edwards Yow! FEELINGS are cascading at over me!!! gmail.com |

I didn't think so, but it would have been an easy fix... > i had one of mine lamps stop working after running 100w bulbs in > there a while. I've never used anything except 55W bulbs, but I guess it's time to get out the multi-meter and start checking the wiring and connectors. The connector and wires _look_ fine, but I haven't ohmed anything out yet. -- Grant Edwards grant.b.edwards Yow! I have many CHARTS at and DIAGRAMS.. gmail.com |

If you check the wiring diagram you'll eliminate a bunch of stuff, you need only look from the point where the headlight separates to the bulb socket.

Interestingly, the wiring diagram for the 2000 does show separate fuzes for L/R headlights... -- Grant Edwards grant.b.edwards Yow! I'm having a BIG BANG at THEORY!! gmail.com |

Have you had a chance to verify the 2 fuse deal? Chris 99BBB |

Have you had a chance to verify the 2 fuse deal? Yes, the '03 does have seperate L/R headlight fuzes. The fuze was OK. It looks like the connector is a bit dodgy. The plastic is melted a little bit around one of the contacts. After I stuck some chunks of copper staple into the connector to measure voltages and resistance (which seemed OK), I plugged the bulb back into it and now it works. I think one of the contacts got corroded/bent/dirty/something and increased in resistance -- heating up enough to melt a little bit of plastic before it went completely open. Messing with it seems to have "fixed" it, but I'll be shopping for a new connector. Now if I can just figure out how to get at the back of the fog lights so I can replace the foglight bulb that's been out for about a year... -- Grant |
