I hear no noise at all when switching from 1-4, but I hear a "click" when switching from 4 to 5(high). It literally just stopped blowing. I checked the fuse, it's good. That's the extent of my troubleshooting.

you may have a bad blower. the click you hear is the relay probably kicking in for high speed. the other speeds go through a resistor. if you getpower at blower then its' bad.
