Hello, did you find out a solution yet? My 2012 Cerato 1.6 (forte) with manual AC does exactly the same thing. AC and recirculation button Never light up when i leave for works in the morning, however it almost always works when in the afternoon when the car has been sitting in the sun for a while, and when it works it blows perfectly cold air. I am pulling my hair out trying to fix this issue. Please HELP!
