2000 323i headlight

[Vietsta101]

Hi, I have a problem with my bimmer's headlight. The xenon on the driver side (very left) does not light up but the one bulb beside it does. I have checked the bulb out (switched it to other side and it lights up fine), I am not sure where to go from there, I'm not sure exactly what is wrong with it. If someone can help me out that would be great, thanks in advance.

only three:

fuses-i believe you have individual fuses for left & right side headlamps;

connections-trace your wiring and check for voltage, opens, or short(including good contact at the bulb socket;

and if the above check out good, you have a ballast gone bad.

Good Luck
