Hey Chris, the first thing I would do is disconnect the HID ballast, (left side) and then replace the fuse and turn the headlight on to see if the fuse blows. If the fuse stays good replace the ballast. Here are the headlight wiring diagrams so you can see how the system works. Also, can you tell me the fuse number that blows? Check out the images (below). Please let us know what happens.

Yep, that powers the left headlight only. Does the fuse still blow when the ballast is disconnected, and you turn the lights on?
