If u dont hear a wind noise on the back glass its sealed. It isnt designed to take direct pressure from a power washer. If it not leaking from driving rain you are good. The back up camera needs to be replaced. Cadillac never had a smooth running sunroof. The rattle is caused by a loose part possiable loose speaker cover or speaker or loose top dash screws by the windshield or a loose molding. Push down on speaker cover and moldings to see if it changes. It could be under the top dash cover. Then you will have to remove the top dash to find it. You need to isolate where the noise is coming from. Gl
