Have same problem on 2014 Sonic LS 1.8L 6sp auto. Did you figure out the cause?

What is your question?

Already replaced clutch relay and evap temp sensor. Replacing thermostat housing assembly next.

What makes this problem better or worse?

AC works great after disconnecting battery for 5 minutes. Then AC clutch stops engaging and we're back to hot air of course.

How long has your 2014 Chevrolet Sonic had this problem?

2 weeks.
