I have replaced all my wiring and my turn signal switch, but I have a problem I can’t figure out.

When I press my brake, my left turn signal lights up. So I put a second turn signal switch in and I’ve got the same problem. Plus, when I turn my right blinker on, both blinkers come on like hazard lights. When I turn my left blinker on, only the left dash light blinks, but both rear tail lights blink like hazards.

So I’ve read through the forum and based on advise in other threads, I have checked my rear tail light housings to ground. I show continuity between both housings and the frame of the truck.

What now? Any ideas out there?
