In my 2016 Toyota Prius Two, My front 12v plug doesn't work but the rear 12v plug does work. Would that be the fuse or the actual 12v plug that needs to be replaced?
It could be either of those, or many other things, but if the outlet worked previously, and doesn’t work now, a blown fuse is the most likely cause. See my posting in this thread: 12v cigarette lighter not working | PriusChat [Edited to add:] That’s a Prius Prime thread, but I think all the information, except the page number in the Owner’s Manual and the document number for the Electrical Wiring Diagram, applies equally to the Prius Two.
