Any time I've had electric windows not respond to the switches, it has been broken wiring. This was with vehicles at least 8 or 10 years old. So far they wire have all been broken inside the rubber wire path on the driver door. The one the protects where the wires cross from under the dash through the door frame and into the door up to the controls. The wiring has gotten old and brittle and the driver door is always used so the wires are being flexed there the most.

There is no rear window lock on the Yukon. The window only goes halfway down because that is all the room there is inside the door. The reason is if you notice that the rear doors overlap the rear wheel housing considerably limiting the room inside the bottom part of the doors. Unlike an XL where the doors clear the rear wheels completely and are able to roll down the window all the way. == ==

All the models that are double cab have a roll down back window.
Try this simple fix. Put the window down then put it all the way back up. Over time and a few bounces the rear window settles down just a bit and this triggers a safety that prevents the defroster from running with the window down, only it's not down enough for you to notice it.
