Hello, I have a 16 f250 the driver back blinker is hyper blinking. I upgraded to LED’s (yes I installed the resistor) over a year go. Yes I checked the blinker fluid as well. Hyper blinking started a few days ago. I swapped the LED back and forth between the left and right sides. They both work fine on the right. This leads me to believe it’s more then the LED’s. Any suggestions? Thanks.
