    Sounds like the Window Motor.
    You need to remove the Door Panel & check the 2 wires at the Window Motor for Voltage.
    It will be a Reversal Rest at Ground Circuit.
    Key On
    Switch held in Up position
    One wire will have 12 Volts +
    One wire will have Ground

    Switch held in Down position
    The wire that had 12 Volts + is now Ground
    The wire that had Ground is now 12 Volts +

    If Voltage test checks good, Replace Motor
    If Voltage test no joy, check voltage at switch & also check for broken wires in the Door / Kick Panel Boot
