I don't know if this helps you, but we had the same problem with my friends pontiac van. They were scared to leave it with the window rolled down while waiting for the replacement switch. So we looked up online for the switch schematics and found people with the same problem, turns out you can pull out the switch, unplug it, and then put a paper-clip between the correct pins on the plug to roll the window up.
I don't know which pins to use on the 2010-2016 Accent, but you might be able to find out if you can somehow get a wiring diagram of the plug or use a volt meter on the one thats working. Just be careful if you attempt this, you could blow a fuse if you do it wrong.
