Prius (2004-09) :: A/C Blowing Warmer Than Normal / No Air Flows

2 days ago I noticed a large puddle on the driveway when I left for work, but I thought it was just condensation from my A/C. That afternoon- 84 degrees outside- my A/C was blowing warmer than normal, even at Max Cold, so then I thought it might have been freon on the driveway and that I'd need to get checked for a leak and replace the freon. But the car wasn't overheated and the next day (in the mid-80s), the A/C worked normally in the morning and afternoon...

Then, this afternoon- 90 degrees outside- it wouldn't work at all. I've eliminated the compressor as the issue (turned on my car, let it go through its start-up cycles, then turned the A/C on high and Max Cold, popped the hood and listened for the buzzing)- it continuously whirs and responds to the changes I make on the A/C settings.

I think the blower motor died, since no air flows at any of the speeds from any of the air vents though I can hear the A/C is on... So my question(s) for you all... does it sound like I'm on the right track? Is there another potential problem it could be that I should be aware of before I take it in to the dealer for a diagnosis? Like a fuse I need to check? Btw, I have a 2007 with 141K miles on it...
