I realize there are a lot of headlamp questions out here already, but I didn't find my exact scenario.

Like the title says, the Driver low beam does not work, but the high beam does. The Passenger high/low beams work just fine.

So far I, one at a time:

• replaced the driver bulb
• checked the fuses
• Swapped relays
• Verified power to the socket
• Verified resistance in the new bulb

Everything looks good except it still doesn't work on low. I also had the above checked by an experienced (but not professional) mechanic.

I haven't touched the passenger side because (a) it works and (b) it requires removing the battery.

I'll try another bulb when I get my hands one one, but I'm really at a loss here.

Suggestions?

Thanks!

Also make sure that you have the correct bulb. There are a number of bulbs in the same format (same base, bulb etc), but are wired differently.

Thanks, I did check that right away, especially since simply inserting it deep enough to get the ring on was quite a challenge. The bulb(s) that I bought, by luck and research, matched the one that came out.

I had to drive it across town last night, and at some point the bulb just magically started working.

Thanks all for the advice (and entertainment!). I may ask more questions just for the latter.

I had to drive it across town last night, and at some point the bulb just magically started working. I wish I had a better explanation for how it fixed itself, but I'll just take that as is and be glad the cure didn't involve any more wiring diagrams.
