If there is or was an issue with the pressure switches or anything else that caused the HVAC controller to shut the A/C off it needs to be reset before it will turn back on. The procedure is in the service manual. I’m not super sure and don’t have my service manual available but it’s something like remove the radio and HVAC fuse for a minute and then replace them. You can also check for HVAC fault codes to see if it shut the A/C circuit off.
