power window issue
I'll admit this problem is in my 90 C2500 but the systems are pretty much identical as far as wiring goes. My passenger window doesn't want to go down, and I know exactly why just not sure what's causing it. For whatever reason I'm not getting a negative. Positive and negative are fine for up just not down. If I feed a negative to the blue wire, even from the door, it'll go down just fine. It's not the switch, I've swapped every switch to find the same problem. Same issue controlling from both doors. I'm baffled.
