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
If both blinker and hazards dont work check your flasher switch.
They dont work. The bulbs are the most problems. Fix it!
Check fuses, and for the blinkers, check also the flasher relay.
Check bulbs Check flasher Check fuses
Check fuses
the hazard switch has two sets of contacts. when hazards turned on, blinkers cannot work,even if hazards dont work.for blinkers to work, hazard sw must be in off position-this reconnects blinker circuits to work normally. BUT-the contacts in the hazard sw get dirty and wont reconnect the blinkers to work
Check bulbs
Check fuse Replace turn signal flasher
Blown fuse, or defective flasher relay if all the bulbs are good.
what can be wrong with the blinkers in a 1994 grand am?
Check/replace turn signal flasher
Check to make sure that ALL turn signals are working Could be flasher
