If all of them have stopped working simultaneously, then most likely you have blown the fuse. The fuse box is lower left of the steering column. The cover snaps off, and you will find a guide to which fuse is which, on the back side of the cover. Locate the 10 amp fuse for the Turn Signals, and use the fuse puller (plastic tool in the center of the fuse box) to remove the fuse. Hold it up to the light to see if the metal "U" shaped element has been broken. If, so simply replace with an identical 10A fuse - if you are lucky there should be a spare right in the fuse box.
I think there are two different flashers one for blinkers and one for the flashers.
make sure if someone unplugged the flashers and all you would have to do is plug it back in
while your vehicle is legally stopped or disabled on the highway or shoulder.
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
it is behind the glove box.

You may have a relay problem your flashers and turn signal are on different relays or there could be a problem with the wiring in the steering column that goes to the turn signal
Driving below 40 miles, long line of traffic, stopped along side of road
When stopped and a possible hazard to traffic on the roadway, or when moving so slowly that you are a hazard to overtaking traffic.
while your vehicle is legally stopped or disabled on the highway or shoulder.
It's the relay. Check the relay box behind the fuse box or the fuse/relay box in the engine compartment.
