Remember, Iím working from a 2011 diagram, my 2013 doesnít have a Set button and could have different modules added, and so can the 2012? You didnít post what fuse you changed. With or without memory changes what controls the power to the mirrorís glass motor? Since you have memory, the black/white wire at the switch could still cause your problem. With memory the door switch sends inputs to the Driverís Seat Module (DSM) and this moduleís outputs to the mirror glass motors. Without memory the switch powers the motors directly.
Iím not and expert, but Iíd confirm the black/white wire with an ohm meter that it is grounded. The only other common denominator I see from the diagram is the DSM. My thoughts are, if you are handy with a digital meter, Iíd check fuses and rule out the black/white wire, since the memory buttons work, the DSM would be my second choice. I donít know what year they added modules, so if you are handy with a digital meter, you will have to test more.
Do your power seats move manually?
Knowing the fuses you changed would give me an ideal if you had a power circuit or control circuit problem.
Iím assuming that you changed the switch by yourself; your truck is out of warranty.
The dealer can scan your truck and tell whatís not working.
