Reviving this thread with a similar problem. I have the same issue on a 2014 TEP.
I brought it on myself doing the USB relocation from the console to the glovebox that's been well documented
here. I moved the USB to plug in my old iPod (which works), but knocked out the power to all plugs up front (Power plug in front and center consoles and USB's). As part of this relocation I added two USB plugs: one in the void in the console and one in the Party mode button location. To power the two USB's I used one of
these on the power wire feeding the console power outlet and then split the wire to go to each of the two USB's. I pig tailed the two USB grounds together and used a bolt in the console for a ground. Could this be the problem?
I was in the middle of the move when I noticed the power was out and unconnected everything and still had no power, so I figured it was a fuse and put it all back together. The 15 Amp P Outlet fuse looked ok, but I change it anyway and still nothing.
I haven't checked the rear outlet, but I do get lights on the 400W switch in the dash when I hit the button.
