All of them are age related, and they do tend to happen around the same time, depending on usage. Yours just so happened to all go at pretty much the same time. FWIW, my 53 Zed had done 90k+ miles when I PX'd it, and that had a new battery about a year before I think, and the window motors seemed like they were not as swish as they should be. I'm guessing they were on the way out for sure. All prefectly normal with the age of your car
