check your fuses should be either under the hood on divers side or on the side of the dash(must have divers door open to view fuse box)
you need to replace blinker can in your vehicle. the flashers and blinkers have separate flasher cans which is why your flashers still work but not your blinkers
"Pull off the roadway and activate your emergency flashers."
Sounds like an electrical problem, check your battery, alternator, and fuse box, and light wiring.
You may want to check the brake lights.Everything runs through the multi-function switch.(the turn signal 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
More than likely the Flasher Relay is defective. Replace it.
I think there are two different flashers one for blinkers and one for the flashers.
check the flasher itself and the switch
try checking flashers and fuses, the check multi-function switch on steering column
Sounds like turn signal flasher needs replacement
If just one side stops, look and change the bulb that isn't on. If none work, replace the fuse or flasher.
You might just need a new flasher or a fuse.
