Recently, my truck started having an issue where my left blinker stops working any time my brake, tail, or reverse lights come on. If I use just the blinker, then it's fine, but when I turn on any other light it goes out only in the back. The front continues working, but blinks quickly. I pulled the circuit board off and switched it to the passenger side, and when I used the passenger side on the driver, it had the same issue as the original. I believe it is probably an issue in the wiring or in the harness. Any ideas?
