Left Blinker Issues

1974 Dart. My left blinker doesn't work. Right blinker works fine, flashers work fine. I get no light at all when I pull the blinker lever down, but it does lock and release on the turn like normal. The previous owner swapped all the bulbs with LED bulbs, but it worked when I got the car.

Any ideas? I dont want to start with pulling the wheel to look at the blinker switch if there are other things it might be.

Thanks for any ideas, signaling by hand in Washington during the rainy season sucks lol
