Never have to use them but on my way to inspection of all places I realize they aren't working!!

Signals work fine unless I push the hazard button, then nothing works.

My first thought was maybe I left the switch unplugged when I was in the dash but the button affects the signals so it must be plugged in

Could this be as simple as the flasher relay?

 

Could be relay they usually don't check emergency flasher where I have lived.
