My heat and air works great it just come on and kick in when it want to... what can this be? Is anybody else having this problem...

Hello, When the heat/air is not working, does it blow the wrong temperature from the vent, or does it stop blowing all the sudden, but start blowing later at random?

I am having the same problem on my 2014 Equinox. The ac doesn't come on sometimes, but then while I'm driving, it'll come on all of a sudden.
