If you are trying to keep it OEM then I would try looking on ebay, junkyard, anywhere else, and then the dealer, in that order. If not trying to keep it OEM then I would buy a new one. It would be as cheap to buy a new one as to get somebody to repair yours. Other than that, just do some troubleshooting just to make sure it isn't something simple that you could fix (ie., blown fuse, bad connection).
