Has anyone ever disassembled their headlight to rebuild/replace the horizontal control stepper motor for the PDLS light?

I've split other lights before to paint the inside, but was hoping it would not have to come to that. After opening the back of the light to view the horizontal control motor, I'm not sure I see another way to get at it.

The passenger side on my 2013 has no left to right movement. Vertical works correctly. Drivers side works correctly. Actuator test were ran with a Snap On tool.

Dash shows a Dynamic Lighting Fault naturally, and the right headlight module shows a 805605 "Dyn. cornering light stepper motor, reference travel" code
