2013 CX-9 Front AC Not Working

Hi everyone! I have a 2013 CX-9 and my AC has gone out. For about a year or so, every time I would turn left, there would be a weird sound coming from near the glove compartment when the AC was on. It eventually started happening when I would brake, also. After a few months of this, my "Auto" AC mode would be constantly at full blast. About a month or so ago, the AC completely went out on me. The rear AC still works just fine, but I can't get anything to come out of the front. I'm thinking I need to replace the blower motor? Can anyone confirm this before I purchase the part?
Thank you!
So I'll plan on buying both the resistor and blower motor (they're both relatively inexpensive) unless anyone else has any other ideas/suggestions??
