If you have two separate bulbs, make sure you have power coming to the socket. Stick the bulb in the drivers side just to make it’s good (even though it’s new, it could be bad). The actual socket might be bad too (corroded).

took whole assembly out and there's a circuit board inside the assembly.
Going to hook it up to the driver side and see if it works. If not then I know its the circuit board.
$475 replacement yaaay!!!

The headlights are on the can bus and controlled by the SJB. Bypassing as you have found won't work because it sets faults. If fuses 16,17 and 30 are good then you need to have someone turn the headlights on and off while you listen to the SJB and you should hear the relay also toggle the high beams. If fuses are good and no relay clicks the sjb needs replacement.
