Recentlly, my left HID headlight have not been turning on. First I figured it was a burnt bulb so I replaced that: didn't work then I had a replaced ballast, still not turning on. Any idea? Might try checking out the fuse box tomorrow or something.

 

check your wires maybe some of them ware rubbing against something and got tear in the insulation so they touch something. that's what was happening to me, because i think if the fuse would go out none of the lights would work. but you should check anyway. best of luck
