I found that it was a burnt out bulb
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
try replacing the flasher. there should be two, one for flashers and one for turn signals
The signal flasher relay may be on its way out.
The bulb is bad. Turn signals and flashers use different bulbs.
Maybe your blinker realay is out.
because there are two diffrent flashers 1 for the flashers and 1 for turn
Could be a blown fuse, or a bad blinker module. First check your fuse panal, and make sure all your fuses are present, and good. Next check to see if you have 4 way (emergency) flashers. If these work on all four corners. Turn off the 4 way flashers, and try your turn signal again. If they still dont work, you might have a bad flasher, or a bad multifunction switch. If the lights dont work when checking with the 4 way flashers, then check your bulbs on all 4 corners. The rear bulbs are usually easiest, and the most important.
Check the fuses aren't burnt first. Then remove lense and check bulb filaments if fine. Try your emergency flashers to see if they blink, if not THEN replace the flasher unit at the fuse box...easy to replace. Hope this helps.
Replace the Flasher Relay.
in mark 8's they use a controler to make flashers flash. this module has gone bad
Probably Flasher
If both blinker and hazards dont work check your flasher switch.
