My mechanic told me my ballast went out. (Driver side) I tore the bumper off and switched the ballast out for a new one tested it and it still doesn't work. I took the headlight out of the passenger side and plunged the whole thing into the driver side, it worked. So, does that most likely mean it's my igniter? Or maybe the harness cable? I don't want to mess with that voltage or pay someone else to take my bumper off and did around in there due to costs. The bulb was brand new so it wasn't just a bad bulb. I just know it's something in the headlight assembly and I'm sure you're all aware it is not easy or cheap to find a new hid assembly. Any input would be greatly appreciated!
