If the dome light works and the rear power locks, then the door connectors should be just fine, which would make it odd that both of the connections for the windows in the rear were the problem. I would think the next thing to try is to disconnect the battery and re-connect it. I had some electrical weirdness a couple of times and that did the trick for me. Leave it disconnected for several minutes before reconnecting.
If that doesn't do the trick, the next point of connection I think is the window up/down switches in the console. The connection for that unit is all one piece, so if the front doors are working and the rears are not, it seems it would be odd for that to be the issue but it may be worth checking to ensure it's firmly connected.
It seemingly couldn't be a fuse either, I'm guessing the front/rear windows are all on the same fuse, and if the fronts work it seems so should the rears.
Try the battery disconnect and let us know how that goes.
