No air coming out of vents? Help!
 

Hi guys, I'm new here and really hoping someone can help! I have a 2002 Elantra and today all of a sudden there is no air coming out of the vents at all! It worked fine yesterday and I can't figure out what happened. No regular air, no heat, no A/C! And it's 85 today ugh! I can hear the A/C turn on when I push the button, and I can hear something happen when I change the temperature dial, but I can't tell if anything happens when I turn the main dial on anywhere from 1 to 4. I don't know a ton about cars but my ex worked on them a lot so I know the basics... Any help would be really appreciated because I can't afford to take it in right now unless I absolutely have to! Thanks guys!

First thing I would check is the blower fusible link. Look for the one marked blower:

It's usually not one of the small fuses you're used to seeing (bottom 2 pics) but a larger, square fusible link (upper left):
