I have the same problem. When I bought my car that side blinker was non operating. I swapped bulbs with the other side and the right side works and the left side still doesn't.

I took apart my dash to try to trace to a broken wire but I don't think I ever measured voltage no-load which is a big clue. It's acting as if there is a huge resistance somewhere in your case: 12v no load and 0v with load. I tried to trace the wire to find out where a bad connection could be but it was getting me very confused since it's apparently not parallel wired with the left front turn signal which works.

I still want to solve this annoying bug hopefully somebody else has already solved in the past
