Blower for heat and air not working

What is your question?

I purchased my "dream car" about 3 weeks ago from a private owner. A few days ago...after quick braking (coincidence?) the a/c starting a squeeking sound, like something was stuck in the vents. I got home and manually turned the blower on high...it blew like a champ...very forceful! The squeeking subsided. The next day...there was no air blowing thru the vents at all...regardless of any setting that I put it on. Could something have become detached from the blower motor? Help..advice..pleeeaaasse! Thanks!
