I just had the same problem with my 95 intrepid and it was the sending unit that needed to be replaced.
try checking flashers and fuses, the check multi-function switch on steering column
try changing the flasher relay. Don't forget to check the fuses also.
Probably
Change front light bulbs
Check your fuses if it is not your fuses i would say check your hazard switch, mine went bad on my Nissan and caused that problem
Possibly a defective Turn Signal Relay. Your four way flasher switch is probably bad. Your four ways will still work but not your blinkers.
Two separate circuits, check the fuses then check the signal flasher relay.
The turn signals and hazzard lights operate by 2 separate "flasher" units. They are usually found up underneath the dash. They are round (about the size of a half dollar) and just pull out. They are pretty cheap. (less than $5)
check your fuses
Check the fuses
in mark 8's they use a controler to make flashers flash. this module has gone bad
check fuses
