AC suddenly stopped working

JSON

My AC has always been super cold and never had any issues with it. A few days ago, I was driving to work with it on and working, and all of a sudden while driving, it completely stopped being cold. It blows air fine, but it will only blow outside temp air.

I don't know if it's in my head, but I felt like I felt a small, quick vibration in my pedals and maybe heard something (had music on so not sure) before it went out. It has been raining hard for the past few weeks here btw.

I tried checking for the fuse in the 3 fuse box locations, but the only one I thought was relevant was the "Air Cont" 10A fuse in the box behind the battery. Are there any others I can check? From searching, someone mentioned that there are 4?

I'm really hoping it's not the compressor. What can I do to check before taking to dealership?

FYI, 2009 with 80k miles.

Thanks
