This is currently happening with my truck.  The guidelines were once there, but are no longer selectable via the button.  The graphic on the button changes to show it should be on, but no guidelines; not in the front, the back, or even with the hitch guide.  Called GM and they didnt know.  Took the truck to the dealer, and they also didnt know.  They said they even tried to re-load the software.  I also have a hour glass symbol in the upper left corner that is persistent whenever in any camera view.  All of the cameras work, just no longer have the guidelines.
