Tailgate window switch- No movement
So i just installed BJs tailgate window switch, but I'm having an issue that I can't figure out. It seems to be a motor grounding issue.
I know for sure the motor is good, working both ways. I was using a direct battery connection to get it up/down for disassembly.
I've got 12v coming from the switch in both directions, confirmed at the motor pigtail. But no motor movement. However, if I operate the switch down, and I apply a ground directly to the opposite pin on the pigtail, I get movement.
What gives? Motor seems to be grounded, confirmed continuity between the housing and the tailgate.
