Hallo forum members

My daughters 2007 cobalt ac is not working. I look under the hood and saw that the clutch is not engaging the compressor. The light inside is showing that the ac is running and I checked the fuse in the engine compartment and it is good.
Any sugestions?
Thank you in advance.

low pressure low freon get a can of gas and add it to the system and see if that makes the compressor run again

 

There is a low pressure cutoff switch, yes I concur.
