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!
 
Check the blower motor resistor first. It is a lot cheaper and easier to replace and can have similar symptoms.
 
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??
