2007 Yukon SLT driver window failure

[Writefast]

Evening.

TLDR: I have no power at the motor harness.

Driver window failed. Lowered window, kept truck running while I mounted a couple of kayaks to the roof. Went to raise window. Nothing. Assumed window motor, would be the third one this year, first two were the rear motors. Ordered new motor. No mas. Assumed module. Installed new module. All other functions work, other windows, locks, mirrors adjust and fold, driver window still will not go up. Finally tested for power at the motor harness. Nothing. Any ideas or suggestions how I track down this failure?

Update.
So far no broken wiring. Tested all wires that run from the main harness, the one that runs the motor, to the fuse box for continuity. All passed. Interestingly, when I plug the old module in I have 11v on both legs of the harness that plugs into the motor. When I plug the new module in I have 0v on both those legs.

Check your driver window up and down switch.
