Hey so I own a 03 350z, everything was fine when i got it but just last month or so my passenger headlight decided to give up but my driver one is fine which weirds me out. Hoping someone can help me out with this situation.

 

Do you have intact fender liners?

 

Do any of the other bulbs in the housing work?

Halogen or HID?

If yes, bulb (or ballast if applicable). If no, harness connection.

 

Swap over the easily interchangeable components to narrow down the issue. In other words, swap the bulbs to see if the issue follows and if not, swap the ballasts (if HID).
