when I turn my 2009 HD Crossbones the left turn signal is on. in order to turn it off, I have to engage the Hazards. Once I turn the hazards on and off. The left turn signal wont work anymore. I might occasionally turn on while I'm riding by itself though. the button does not work

 

have you changed to non-spec bulbs or leds?

this can screw the turn signal module.

2.) crossbones is a softail model?
there is another section of the forums with more fist hand experience
