I have a 1980 Malibu with power windows and I am trying to install the door glass and need to operate the window motor in a car that has no motor or transmission.I took the window out several years ago to do some work on the car and took the glass out with the window in the down position but now need the window up.There will not me a motor in the car for a while so I just need to know if I can operate the motor with just a battery.My plan is to go to the junk yard and get a plug and plug it in the motor and then attach the other end of the wires to a battery,is this possible.The rest of the electric system will be completely seperate if I do it this way and I can just send power only to the window motor.There is a brown and blue wire going to the plug.Is one positive and one negative or is one up and one down.There is a wire up by where the switch would be that needs to be grounded.So is it possible that i just attach that ground to the door and then power to either the brown or the blue to work the moter.Sorry for the long explanation.
