AC making buzzing noise

My husband and I just bought
A 1991 American by cobra motorhome. This company was bought out by forester.anyway I had the ac running when all of a sudden it made a buzzing noise. It just has the one ac up front. I did notice the previous owner for whatever reason taped the other side of the cover where I assume a vent used to be. Any ideas what the buzzing noise is? I haven't opened it to look because I don't know what I am doing. I never owned a motorhome before. On other posts someone mentioned wasp nests. I hope that isn't the case. My guess is it's a broken fan blade.
