So I realize the whole headlight ballast issue has been discussed over and over, however I think I have got a weird situation. When the car is not running, the passenger side headlight does not die, however as soon as the car is started, it either dies during starting or a minute or so after. I have tried switching lighting relay 1 and 2 with each other and with other same relays, I have tried switching fuses, and I have traced the electrical connection. None of those do any good. What confuses me is that when the car is not running the headlight doesn't die but when it is running it does...odd! To get the passenger light to come back on I either have to turn the headlights off and back on or if I'm parked unplug and replug in the ballast, just unplugging and replugging the ignitor doesn't work. Any ideas on how to fix this? Or do I just have to change the ballast and thats the final answer? Thanks!

 

have u bought a new ballast to try? to me sounds def like a bad ballast. vibration coulda killed it

 

I've had a somewhat similar problem with the passenger light. Except on a few occasions i had my lights flipped on before starting the car and the passenger light wasn't on. Waited half a minute and turned on the car and the light came right on with the engine. Come to find i need a new ballast so I'm just getting a new HID kit because it's more economical.
