As far as I know, GM dosen't make them anymore, they discontiued them years ago. So you'll need to find someone who has an old one or try to rebuild yours. I ran into a prob with my power rear window, but I just got rid of it all together, I went totally manual rear window. It costs about $250 and about 3 hours of your time but to me it is totally worth it!. Hope this helps, or at least narrows your options down for you.
