Dash lights and turn signal issues

[19724x4plowboy]

My driver side turn signal light, on my dash cluster, is always half lit up when the lights are on. But all lights are working, front and rear. Except rear driver side marker. I haven't looked at it to see if it's a bulb or not. Wasn't sure if the cluster even cared if it worked or not. My problem is the turn signal doesn't work all the time when applied to make a "left" turn. Didn't know if I have a bad ground issue somewhere or just a bad turn signal switch. This is my second column and it is the doing the same as the previous column also.

Any ideas ??? What am I missing???
