You got turn signals? I'm thinking if you got turn signals, then your relay may be good...no relay, no signals. My hazzard switch has a "sweet spot".....try a little wiggle action on the switch, small rocking motion....don't ask me why, I've cleaned. greased and still have to fondle the switch to get it to work.
