My passenger window control from the drivers side won't work at all and from the actual passanger door I can only get it to go down, Here is the problem- it is down and I need it to go UP. It will not be hard to fix since the motor does work or it wouldn't go down but need diagram of wiring so I know where to look for the problem. Any suggestions or advise are welcome. Thanks,

Katie, the diagram and troubleshooting pages you need are in the Buick shop manual. I can scan these and send to you. Going by your profile info, you need the Century diagrams, is this correct?
