Ok. I thought the 10 seconds thing was the dead giveaway, but if there's no voltage even getting to the motor, have you checked the wiring between the driver's door hinges?
Your truck is new enough that there might be a Body Computer involved with running the power windows, but regardless, if the 12 volt power wire is broken, none of the windows would work from the any switches. Each door has it's own 12 volt feed wire that comes from the driver's master lockout switch so if that feed wire was broken, only the driver's window would still work. If the ground wire was broken, none of the windows would work because all of them go back through the released driver's switch assembly, then to ground through the ground wire in the driver's door.
To have just one or two windows not work would seem to eliminate broken wires as the cause. Next, I would head to the switch assembly. By the way, are you using a test light or a dc voltmeter? If you are grounding it to the door, you might be getting inaccurate readings. Try to find a nice shiny ground bolt under the dash if you can. Sometimes the door striker works too.
If you have an ohm meter, when no window switches are pressed, both motor wires must read continuity to ground. Unplug the connector because one open circuit can read to ground by going through the motor. If either wire reads open, there is either a break in the wire back to the switch, (rather unlikely), or an open / burned switch contact. I know it can be hard to figure out which wire is which terminal on the switch, so you might have better luck looking at the rear window first. That switch should only have five wires. (I have to do this from memory of Chryslers which are very similar). One wire will have 12 volts, if the master cutout switch is on in the driver's door. Disregard that one. The other four must all read continuity to ground. There are two circuits, one for each motor wire. Each wire goes from the motor, through the LR switch, LR door hinges, through the LF door hinges, through the driver's switch assembly, through the ground wire between the door hinges, and is bolted to the body.
At either switch, pressing it first opens the ground path to one wire, then the contact moves over to touch the 12 volt contact. If you measure voltages at the motor, you will have 0 volts on both wires until you press either switch, then you will have voltage on one wire or the other, depending on the direction the motor should run.
Try making a few of these measurements, then holler back with your findings.
