Could very well be your flasher relay located where your knees would be. Behind that panel is about a 3" long flasher about an 1-1/2" wide. Different years have slightly different location, but are right behind that panel. Mine is attached to the back of that panel. Try pulling one from a junkyard to test it. I had the same problem 3 weeks ago with my flasher on drivers side. I'm running an LM486 flasher which is LED bulb compatible, no need for resistors anywhere with this flasher.

Check wiring to the back of the headlight itself, i had a wire rust off the passenger side light (headlight worked but not the blinker) and needed to solder it back on. After that the blinker worked fine.
