Default 2004 9-3 ARC - HID Headlight Issue

My driver's side Xenon HID headlight will not illuminate. I have switched the whole headlight assembly to the passenger side and it works fine. I measured the harness voltages and they are the same from passenger (working side) to driver (non-working side). I also confirmed that the harness ground (black wire) is tied to chassis ground on both sides. Stumped.

Anybody have any ideas, would appreciate some help.

Finally gave in and took it to a shop. It was the UEC not sending signal to the 342 module. So after $630, I have working headlights again.
