Hey guys, new to the forums. Just bought my 2003 350z last week. The car is great. But I did run into an issue. As the title states, my low beams aren't working. I checked the fuses and they're all good. I replaced the relays for the low beam and fogs even though they were fine. So far nothing. I checked the bulbs and they were good as well. I took 4 other brand new ballasts and bulbs, hooked them up to the wire that powers the low beams and I noticed that there is no power. I've been researching what the possible problems and solutions are to narrowing it down to three options. Those being:

- BCM
- IPDM
- the actual switch for the headlights

I'm not sure if anyone else had this issue or if anyone has any helpful input but anything helps. I'm pretty handy, so if one of these things have to be replaced I should be able to do it. Also the part numbers would help as if I can't find anything else I'll be going down this list buying parts until they work.

Thank you in advance, and I look forward to becoming part of this community.

 

Since your high beams work, I'd start with this. Trace the circuit and check it with a multimeter. If it's bad, replace the entire switch assembly.

 

Thanks zakmartin for the reply. I'll give it a try. Hopefully that is the issue as I would think it would be the cheapest route. I tried looking for the part beforehand, but couldn't find it online. Would you know the name of the part or a part number by chance?
