Why won't my liftgate work?

I've tried the shipping fuse and battery disconnect resets, the wiring is all factory but doesn't quite match the schematics so those aren't helping, no fuses are blown, and the CAN stored in the BCM and actuators are receiving and outputting power. The Power Door switch wont turn on when connected to the code reader, and the liftgate won't latch, unlatch, or lift or close when any of the buttons are pressed. What's going on? Please tell me this can be fixed with actuator replacement before I have to take it to a dealership.
