2014 Sierra LED taillight hyper flash

[Swifty]

Hello all I have a 2014 Sierra put LED tail lights in it, just the other day I got a message stating indication left rear turn problem and my turn signal started hyper flashing, left side only . I have these lights for over a year now with no issues at all, first time doing this. Been looking through old forums but not really finding my solution. Please help. No obvious issues have been found, light flashes normal when hazards are turned on?

You most likely have a bad resistor on that tail light. I have the same problem right now - right rear tail light is hyper flashing. I unplugged my resistor and nothing changed so I'm assuming the resistor is bad. Did you install them yourself? Do you know if you had a resistor wired in? You might want to take a look there first if your other side is not hyper flashing (like mine). If my resistors weren't hard mounted to my frame, I'd swap the two and see if it moves from right to left. I am actually about to order one from @pgamboa.
