After looking at the assembly, getting to the corner markers doesn't look easy.
Anyone have a helpful how to link they could point me to?

I just replaced my fuse panel because my parking lights stopped working.
I've got the new one in, and now the two front marker lights aren't working (the ones directly next to the headlights on the corners).

 

i replaced mine and as i recall they are connected by a single screw on top of the headlight housing, unscrew em and pull em out.

 

the only screw is the one that goes in from above. it may still seem like its not gonna come out but it will. you just have to play with it for awhile till it comes out
