I'm new to the 350Z ownership and this forum.
I bought a 2003 Touring edition from a family member who lives in Reno NV and I drove it back to my home to Louisiana. Great road trip!
After I get home I'm driving around town the next night and I notice I don't have a drivers side Low Beam. It was working OK when I left NV.
I also remember seeing moisture on the inside of the drivers headlight lens the day before and just before I got home from the trip I drove thru a windy driving rain storm so maybe that headlights seal is leaking.
Next, diagnose the problem. (here's the layout before starting) Passenger side works great, high and low beams work. Drivers side, only high beam works.
1st I started with the fuses (checked out OK)
2nd I bought a new HID bulb (new bulb made no difference)
3rd I wanted to swap the ballast from the working light to the non working light to see if I had a blown ballast. I removed the bumper and swapped the ballast (no change) Also tried different bulbs (no change)
OK guys, please tell me what I'm doing wrong. I need to drive the car out of town Thursday night but can't go with no drivers low beam.
I appreciate any and all help, Thanks

Forgot to mention, while testing, I noticed the passenger side low beam also no longer works. So both headlights do not have low beam ...

 

How did you check out the headlight relays and fuses? Do you have a FSM to guide you?

 

You need to get yourself a wiring diagram and check for your low beam feed and ground, ground is usually shared between the two beams, so it’s likely good, but I’m not sure where the actual feed is from, its likely from the bcm.

 

I found the problem.
It was the Ballast and Igniter
This was my first post, did I post it in the wrong place?
Thanks.

 

Glad you figured it out. You did fine with your first post and posted in the correct forum for questions like this..

 

Thanks DK :-)
