Blinker flashing fast, all bulbs work, hazard lights working fine
So, I'm lost on this one and have checked multiple threads. It all started when my left blinker began blinking very fast (front and back). Just the left. Then, I noticed it would blink at the normal pace and then start blinking fast all of a sudden. NOW, the right blinker will blink at the normal pace and then pick up speed all of a sudden. All bulbs are active and blinking - none are burned out. When I activate the warning/hazard lights, front and back all blink at the standard speed. Again, when this happens, it is to the front and back blinkers. I'm lost. Also, I have not connected any trailer lights recently. (Other posts have suggested that may be an issue).
It is a 2011 Jeep Rubicon. Any help would be great. Thanks in advance!

The blinkers/flashers have no relay. It's all triggered by computer.
The closest thing to a relay in the system is the device in the cluster whose only function is to make the sound we all expect to hear when the blinkers are operating.
OP, are all your bulbs stock, and of correct part number?

Yes - it's crazy - all of my bulbs are functioning and appear to be in good working order - all LED. I believe they are the original stock bulbs on the 2011, though I am the second owner. They have been working perfectly for about a month, and then all of a sudden - it started with the left side. Blinks fast, but bulbs still actually blinking. Then the left side would blink at normal speed for a few seconds and then go to the rapid blinking. Days later, the right side followed suit - a normal blinking pace to begin with and then it would speed up. When I activate the warning flashers, both sides - front and back - blink at a normal pace. Mind blown.

I would add resistors to anything that was changed out to an LED. If the hazards work fine I am thinking it is because the combined load of all the flashers has equaled the load of 1 incandescent. Computer happy...flash...flash...flash.

Therein lies the problem.
