Blower motor quit

Thanks for being here guys & gals. I'm new to FABO. 65 Barracuda 273 auto w/AC. Blower motor has been making a sickly sound that fades in & out depending on how fast the blower is running. A coupla days ago it started blowing a good bit stronger which was puzzling but it the extra cold air felt great. Today while out running errands I started "Goldie" with the air ON, which I try not to do, and, no blower, no compressor. Fuse is OK. What should I do next and any idea why it started blowing so well just before this happened?
