Blown bulb.
a bad blinker bulb. replace the bad one and it'll blink fine.
If both sides (right and left) don't blink on and off, the blinker "can" may be the culprit.
I think that someone is pulling your leg. There is no such thing as 'blinker fluid'. Sure, it's right next to the muffler bearings :)
It sounds like it needs a new flasher for the turn signals.the hazards have a different flasher.
Left blinker= [Right blinker= ]
Right side of the oil pan.
Could be one of your belts.
It is located under the rear right side seat
under the dash right hand side.
It usually means you have a bulb burned out on that side. I can't remember if it's front or back.
sounds like an electrical fault i would take it to a mechanic
