Blower is intermittent

What is your question?

The heat in my car works fine but the blower for it keeps not working. I can put it on 1,2,3,or 4 and it won't blow but then the next day it was working again. Sometimes while it's working it will sound like I turned it down to a 1 for about 3seconds then it will blow high again. Not sure if I need a new blower or if it's a wire problem or what.

How long has your 2008 Saturn Aura had this problem?
