Your turn Signal Switch is burned out. Call your local parts house and ask them to give you a price on a Turn Signal switch for your car.
Could be the switch on the steering column...take it to a mechanic
Probably the turn signal flasher
There is two flashers involved, one for the signals and one for the emergency flashers. Perhaps you changed the wrong one.
bad bulbs
It could be the turn signal bulbs, some vehicles use separate bulbs for the hazard and turn signals. It could also be a bad switch or wires for the turn signals.
Check fuse,bulbs, flasher
check you light bulbs
Check the fuses or change the bulbs.
you prob need new bulbs
have you check all the bulbs? if one of the bulbs are bad they will light up, but will not blink.
check your fuses first, then check your bulbs and then your relay.
Either your turn signal bulbs are out or the wiring leading to your turn signals is not properly connected. Most likely your bulbs are out which will only cost a few bucks.
