Rear window glass won't open. no power
Hello, I have a 1999 GMC Jimmy SLT. It has the rear hatch style, not the tailgate style. I've got the panel off, and the actuator out. The thing is, when I hook a test light to the actuator plug, and push the button, I am not getting any power there. All other power windows, locks, and accessories work, such as heat/power seats, mirrors, etc.
I am not sure if there is a specific fuse or relay I should be looking at for this? In the manual it doesn't say there is a fuse for this. The rear hatch power lock works fine.
The rear button has 2 wires, that go to a connector with 4 on the other side. One is hot, one unlocks the hatch, and one locks it. The other didn't seem to do anything.
Perhaps I just need to replace the actuator, but it seems like there is a problem getting power to it.
Any help would be appreciated, I've tried searching and looking at related posts, most of the rear glass ones seem to be about how to open the tailgate when the window won't open.
Thanks all.

the one that does not do anything is most likely ground. But if there is no power going to the plug from any of the wires, then the problem is farther up, I would remove the switch and test for power there.

Ok, so I went back and checked again.
The switch has 2 wires, the go to a connector. When disconnected, one side does have power. When I jump the power from one side to the other, I still don't get power at the either of the wires going to the actuator.

The wiring doesnt go direct from the switch to the actuator. The switch has a two wire connector on it. It plugs into a connector that has 2 on the switch side, and 4 on the other side. Those 4 go to the door latch. The wires for the actuator from there dissapear into the harness. There must be something that says whether the glass should be locked or not, a fuse or a relay in the system somewhere perhaps as well...
