2015 Chevy Sonic A/C & HEAT not blowing and clanking noise

When I turn on the air in my 2015 Chevy Sonic there is a loud clanking/knocking noise and no air is coming out of the vents whatsoever.

This started at the end of the summer and wasn’t a big deal with being able to roll down the windows but now that winter has hit, we need to use to the heat.

On a limited budget at the moment. I’m just trying to figure out if it could be something lodged somewhere and what steps I could do to pinpoint the issue.

Thanks!
