What do you check if the blinkers don't work?

The first thing to check is the bulbs,if one is burned out the blinker won't light up on the dash(most cars).If it lights up but does not blink it is usually a flasher unit.The flasher unit is located on the fuse panel of most cars under the dash.The flasher is round about the size of a half-dollar coin.It just pulls out from the panel.Hope it helps...JD
