Sending positive current to both wires of an electric motor can be dangerous and may cause damage to the motor or electrical system. Electric motors typically have specific wiring configurations to control the direction of rotation, and reversing the polarity may cause it to rotate in the opposite direction or create unwanted behavior. In the case of an electric window, there are usually separate wires for raising and lowering the window, and these wires should be connected correctly according to the manufacturer's specifications.
