Drivers window dont work,

[Kushdog]

my Drivers window dont work. I replaced the whole motor assmbly and that was not the problem, ever since i boght the Tahoe the window only work when the dorr was shut, but now dont work at all. the other 3 windows work with the door open or closed.

1. swicth is bad?
2. bad ground?
3. messed up wires somewhere under the dash?
4. ??????

what do you think? every have that problem and figure it out?

I'd be looking for a pinched/ shorted wire in the door wiring loom that goes between the door and door jam since it use to only work with the door closed!
