Xenon Auto-adjust issues

I replaced the bulbs on my prefacelift coupe with AL headlights. The bulbs work great but the auto adjust on the passenger side seems to have a mind of its own. The drivers side moves properly but the passenger side seems to vibrate and make a humming/buzzing sound. Right after installing the bulbs, i saw the passenger side was out of adjustment and I adjusted the beam up to where it needed to be. After a drive around the block, I parked it and the beam was really high. I adjusted it back down and now its really low. Some times the passenger auto adjust works, other times it just hummms/buzzzes.

Is it possible to take the headlight apart and inspect/repair the mechanism inside the passenger side light assembly? Im going to take the light assembly out after work. Any tips?

update- I took the passenger headlight assy out and the ball attached to the auto adjuster is in its correct position in the white bracket. The white screws in both adjustment knobs are not broken either, they move the headlamp as they are supposed to.
