07 cobolt. Ac working great, artic air. The next day no ac.
The relay and fuses are good. The compressor engages.
Blower is blowing, lights on dash are on. High and low

Any assistance would be good. Perhaps I missed a relay or
pressure switch. Ty in advance.

Your AC system needs to be recharged with a can of R134A
I agree with brotherben. And if it needs to be recharged that means it needs other repairs. It's a sealed system so if refrigerant is needed that means it has leaked out somewhere. That is a job for professionals with the proper equipment and experience. Don't waste money on recharge kits. Just take it to a shop.
The high and low pressure sides of the system aka freon are good. It is full, never lost pressure. Thank you though.
Then possibly a compressor that's not working or the mechanism in the duct work that directs cold air instead of hot air through the venting is not working.
Check and see if air return flap is stuck open under dash it works off vacum
