I have a 92 hatch and my blinkers won't work. I tried changing the relay, all it does is make a buzzing sound when I try to signal. . .

 

Did you check the blinker fluid?

 

if i were you i would sure check that damn blinker fluid...ya noe...

 

it is unlikely that 2 bulbs would go out at the or about the same time. but maybe one was out for some short time and you did not notice it. when you put the signal on , do you get a solid light for the turn signal light.
Check all the bulbs for continuity.
