Try this first. To check if your blinkers are working properly, with the vehicle running or key in "on" position, lift the lever on the left side of the steering column up until it clicks. That should actuate the right blinker. Next move the same lever down 2 clicks to actuate the left blinker. Return the lever to the center position when finished testing. Problem solved! When driving, you shouldn't have to return the lever to the center "neutral" position as the auto makers who dared to install this feature have come up with a brilliant self- cancelling function that is supposed to turn the blinker off after you finish making a turn in the direction of the blinking side. You will, however, have to re-initialize the blinker for each turn you make. Also, there is no need to use the blinker around curves in the road or when travelling straight ahead. It seems that many people have not mastered or even attempted the technique for using this amazing option. Hope this helps.
The blinker fluid article also failed to mention to re-check the fluid level after several applications of the blinkers, due to trapped air in the system. The blinker system is self- bleeding and any trapped air will be expelled through the vent tube on the back side of the resevoir. The fluid will eventually replace the expelled air, and that is why the level should be re-checked.
