Oh, got it back from paint, looks a lot better

More than likely, as others have said, one of the belts or pulleys.--My air-con belt was starting to crack in lots of places so I fitted a new one.--This new belt, when I switch on the air-con, happily whines away all by itself. As the belt was new I guess what I can hear is wear on the pulley.----
