How to fix window cable on 98 regal?

I already changed the motor and the window (on front passenger door) still doesn%26#039;t go up. But one of the wires seems shredded. Any ideas on how to fix this? will i need a kit or just another wire? The window is also sitting right, nothing wrong there and all the other windows work fine too. On this one it goes down but not up. When i use the passenger switch or even the drivers switch i can%26#039;t roll it up and i can%26#039;t unlock the passenger door either. I have to use the remote to unlock it. Is it possible that they are both affected by the same wire?|||chase the wires from the switch they usually have a plug under the dash unplug it and see if the parts department at your local Buick dealership carries that part of the wiring harness if not try to find one in a junkyard.
