    Passenger side power window is stuck down. I think the passenger side window switch may be the issue, or it may be both switches. One wire connection is defiintely broken on the pass side connector.

    What wires do what? I would like to jumper wires together to run the window up as a test. Let alone just to have the window up.

    Steve I’m at home right now I’ll take some pictures of my car tomorrow and post them.

    not so much an issue of pics -- everything is intact but 1 wire and I know where it goes.

    I just want to know if I need to jumper red to blue to make the window go up, or if brown needs to go to black, or whatever. Would rather not melt anything while guessing...

    These are fairly archaic systems. The switch feeds both the negative and positive side of the circuit. It simply swaps the polarity to make the window motor run both ways as needed. So if you need to jump the motor, one wire going to the motor will need grounded, the other will need a 12v supply. If the window moves in the wrong direction swap the wires.

    I'd guess the broken wire you found is the issue, fix that and see what happens.

    reconnecting the wire did nothing.

    There are 5 wires, which is why picking two is dicey.

    docgsx It's not a GTX

    Just curious here Steve, did you put a “window racer” unit in there at any time?

    Use ohm meter to see which wire is broken

    Ordered switches. Have motors. Do not want to swap anything if not necessary.

    I would like to power the window up. If I put 12v to the wires, which 2 wires?

    Only two of those wires actually go to the motor. You'll need to supply both a power and a ground to make the motor work.

    I don't know what year that you have, but for a 1986 Cutlass, Dark Blue,(E), and Brown, (D) are the wires from passenger switch to motor. Those are the ones to apply power and ground to. Pink, (B), is 12v from breaker, Blue/white (A), and Tan, (C), come from master switch.

    You can’t really screw anything up, as in “fry” anything, the window motors and door lock solenoids are designed to work with the polarity switched, that’s how it goes up/down
    I’m assuming you have the door panel off?
    The reason I ask is you DONT want to put 12 volts to the door speaker:eek:
    Just start putting power to the window motor wires, one of the positions is up.
    Would be nice if you could run this motors on 24 bolts, those things are PAINFULLY SLOOOOOOOW!

    No, as I noted in a related Window Racer thread, the idea kinda scares me.
