Drivers headlamp not working

What is your question?

I need help. I have had issues with my left headlight for some time. Originally my left low beam stopped working out of nowhere but it would come on every once in a while after turning low beams on and off. After thinking it was a sort I recently switched out the entire headlight and housing to brand new ones (both sides). Passenger side works great but now nothing works off the drivers side headlight. Turn signals high beams or nothing. Now I’m not sure if it’s and bad factory harness, issue with the SAM or something else. Please advise. Thanks in advance.
