After troubleshooting and finding the ground that controls the front lights (Side markers, and front park lights), Cleaning the contact and making sure there was a good ground to the chassis, I still couldn't get the left front side maker to work. So I decided to see if it would work while the turn signal was engaged.
That's when I saw it!!!!!
the left front turn signal wasn't blinking.
Could it be that simple????
I removed the bulb from the housing and as soon as I pulled it out it started blinking (it was loose in the socket). when it started blinking so did the Side marker
When I turned the blinkers off, the side marker lit up as it should, and the cameras worked accordingly.
Simple solution for a confusing problem.
