hey Kiran What were the weather conditions in which you experienced this behaviour by the AC system? As per what you have written you usually set your AC @ 21deg and keep it in AUTO mode with recycle and you feel warm after some time. 1) do you adjust the blower speed as well when you feel warm? 2) do you sweat when you feel warm? 3) Did you also select whcih blowers shoild air come in from? Punto 90 HPs AC is not like ordinary cars AC systems even if you keep the AC at auto or manual the cars 1st priority is safety and in case based on its algorith and calculations if the cars systems feels that as per the current settings there is a chance that either the front window or the back window will get mist on it the car will automatically override the user settings and do whatever it feels best to avoid such a situation.
