Headlight is driving me NUTS!

Passenger bi-xenon adaptive headlight is my nemesis! Light is out and I can't figure out what could be causing it to be out!

I took both headlights out.
Swapped control unit/ballasts, both work fine.
Checked/swapped the headlight leveling motor control unit next to ballast and those work fine too.
Plugged drivers side headlight into into passenger side and it worked(to rule out if it was the passenger side plugs).
Then plugged passenger headlight into drivers side and IT WORKED!
So the passenger headlight that is my nemesis is actually working when plugged into the driver side plugs!
Put all back together and thought I was done, now that the headlight went on. WRONG!

When I plugged the drivers side headlight in, the passenger side goes out.
No flickering.. Just out.

What the heck could be the problem? I've checked everything I thought!

I think it has to be a lack of electricity going to the passenger headlight when the drivers headlight is on. And I've already checked the ballast!

Please help if you have any ideas. Thank you!
