I have a 2012 Chevy Cruze and am experiencing intermittent AC issues. Normally AC blows hard and cold. Every now and then it'll begin to blow hot and a -40° symbol appears on my radio display in the top right corner. It'll last a few hours to a day and then returns back to normal. I'm thinking it's the Evaporatore Core Temperature Sensor but wanted to check with my fellow Cruze owners.
