2013 Chevy Spark - Air will not blow for Air Conditioning or Heat

Hello,

I have a 2013 Chevy Spark. Within the last 2 weeks while I had my air conditioning on the air suddenly stopped blowing. Each time I turned the air off & kept it off for at least 5 minutes. Turned it back on & it would blow just fine. The last time that this happened however it would not start blowing & has not blown any air since.

When I turn the knob to turn the air on I can hear it make a click noise like it is engaging, but no air blows. I have tried both air conditioning & heat, neither setting has any air blowing. Does anyone know what would be the cause of this/what part needs to be replaced?

Any help or suggested would be much appreciated!
