Trailer Wiring Issue
I have running lights, brake lights, right and left turn signals working. Only problem I have is when I have the running lights on, only the left turn signal does not work. Turn the running lights off...

You are right, go buy a couple bulbs, you should have spares anyway, but that is not the problem. The problem is in the ground (neg) wire, maybe a bad socket....neg side !
