Replace the Turn Signal Flasher Relay.
Check the fuse
check your fuses
Bulbs? Sockets? Steering column switch?
I believe the flashers are on a separate fuse than the blinkers, that is where I would first start to look, is the fuse box
There could be numerous problems that may cause this fault. Personally, my blinkers started going out (working sometimes and sometimes not) and what I found out is this...The flasher switch that is located in the dashboard above the radio is faulty. When my blinkers do not work i just tap down on the flasher switch without turning it on and my blinkers work again. Shotty electrical work in this car if ya ask me.
Could be a fuse issue if they have stopped working or a dynamo, alternator, generator issue ie, not putting out enough current.
Presumably if both stopped working at the same time the bulbs are okay, but worth checking. The fuses might be fine but the actual connection between wires might be loose/disconnected.
Sounds like an electrical problem, check your battery, alternator, and fuse box, and light wiring.
I think there are two different flashers one for blinkers and one for the flashers.
Change front light bulbs
Check the flasher located in the fuse block inside the vehical under dash on drivers side
Check the Fuse.
