Passenger window won't work

[Biggriffin]

My 2006 k12, the passenger window will not go up or down, I have power to the switch, changed the regulator, neither switch will operate the window,the switch led is illuminated,,

Check the power at the motor contacts at same time as pressing the window button to check if voltage is reaching the motor, if so, look for a replacement, or if no voltage check for broken wires from the switch to the motor?
