I searched and didn't see anything like what I've got going on....my blinkers work perfectly....and then nothing....I've pulled fuse block apart and cleaned it....added all the suggested grounds, updated front bulb sockets to 97+, rear is a flatbed with led lights. When they stop working, I wiggle all the wires under dash with no change......then just randomly they work again....when they aren't working i have found that the purple wire on the multi function swith will be blinking with test light but blinkers aren't working....if i had hair I would be pulling it out. Open to suggestions
