just to get it up for now the fastest and easiest way i've found is to run to jumper wires (a power from the bat and a ground from anywhere) and take your plug of the window motor, put one on one side and the other on the other terminal, if it doesnt go the intended way swap the wires to the other terminals and up she goes, if not you have bad power or a junk motor. Switches on ALL gm mid-size cars are freakin junk!
