Fuse for Liftgate

My power liftgate stopped working today; was hoping to check the fuse but the fuse cover doesn't specify which one it is. Anyone know?

it's in the manual I bet..

The FSM, likely. Not the plain old Owner Manual though. I found another thread (1G FX) that said to check the 15A fuse near the fuse puller; didn't see one near it so I checked and re-seated every 15A fuse in the box.
I then checked the box in the engine compartment; there are only (2) 15A fuses and a bigger, block one labeled "DE". I checked and re-seated all those. The engine box cover actually says 'rear door xxxxx'; but it still doesn't work. You're supposed to have ability to manually open the hatch if the switch is in the OFF position, but I can't. Only way I can open is to crawl into the back and use the true manual release lever.
 
Does anyone know how to bypass the motorized/electrical method and just open it manually (without crawling) into the hatch area?
 
I recently blew the fuse when I tried to open the hatch after a sub-zero overnight; frozen shut. It is not explicit in the manual and I used an on-line fuse box diagram
(Infiniti QX70 (S51, 2008 - 2017) - fuse box diagram - Auto Genius) and replaced the 30 amp, pink, low profile fuse. The top of the fuse box does show which fuse is for the "Automatic Back Door Control Unit" and according to the document is listed as "Q".

One 50 degree day, some Lexol rubber/vinyl protection on the gasket, a new fuse and hopefully the problem will not happen again.

I’ve looked at as many fuses as I could find, and they all “looked” good. Does anyone have any ideas about what could be wrong??
 
The fuse I replaced also appeared to be intact but I changed it anyway; that did the trick. I figured it was worth a $5.30 investment. Whether it was actually the fuse or the resulting power interruption to that circuit causing a reset I couldn't say; easier than disconnecting the battery.
 
Modern fuses have two small contacts that can be used for testing with an ohmmeter without removing the fuse. Never just look at a fuse or a light bulb. Test them with a multimeter. Put the meter in "diode check" mode and listen for the beep. If no beep, check again, still no beep, replace the fuse (or bulb).

Do you mean that 15amp fuse under the hood, the larger square, pink one?
