Both my turn signals are blinking very fast, but my hazards are fine.

HI You can a bad flasher or another burnt bulb if the front n rear are working also check the side markers. Good luck Lionel

have u installed new or aftermarket lights at all?

change directional flasher, 4 way flasher is a different circiut

hazards are on a different wiring system., make sure all lights work.. turn, hazard, sides, (in side mirror if equipped)...blinking fast means the system is reading a resistance so atleast one of the bulbs is not functioning properly....after all are checked, let me know..

make sure u check the fuses and then change the bulbs again
