Have a 05 chevy classic, same as the 97-03 malibu. I searched online and it's the blue wire, so I tried both blue wires on top, hooked a wire to the positive post of the car battery, and it sparked so both blue wires is not it. The bottom wires all go to the 3 other doors so that shouldn't be it. Just trying to put the windows all up and leave it since it's a old car. I think there has to be a positive wire to send all power. I got another control unit from a junkyard and it doesn't work, so it's probably no power. What other wire could be it? Thanks

It doesn't seem to have a fuse for all power windows like other cars
