You can have a few issues that will cause a top to fail. First check the fuse for the top pump motor. If it is good and you can't here the pump running when you actuate the switch you probably have a failed convertible top pump motor. As for your window, if you run the window switch and you here nothing, then you have a failed window motor. If you hear crunching and grinding sounds when you actuate the window, then you have a failed window regulator.
