Sorry, I just reread your original post, word-for-word, and see where I first though you wrote 'it works from the driver's controls...' you really wrote 'doesn't even work from the driver's controls....' or something like that. That removes the floor connector and the child switch on the back of the door, so yes, it looks like you're down to chasing wires.

Although I don't have the schematics and I haven't worked on this car much yet, if it's like any other modern GM vehicle, it's all controlled by the BCM, which then controls relays to control the window motors. Or it's all controlled by the DDM. Either way, for both windows to fail to work, I'd say it's a power issue to those doors if they're on a common circuit.
