Can't Adjust Headlight Beam Aim

I have 97-98 NissN Silvia headlights and on my passenger side, I cannot adjust the beam aim on the lows. I can adjust the other low and hi’s and get the feeling of slight resistance on them which I do not feel on my passenger side. I am guessing the screw is out of place somewhere on my passenger projector or something. What are my options for fixing this? I wanna have my passenger side shoot further so I don’t have q blind spot on it.

if you are sure its an internal issue, just pull it apart and look to see if anything is blocking it from moving.
