Greetings', a month ago I have bought used Aveo t300 and I'm loving it. It is my first car ♥

I have noticed that sometimes when enter the car and give contact? BLUE backlight gets lit for brief time at center console (Radio, HVAC control system Backlight!) and then it disappears and sometimes does not appear at all

Does anyone have an idea what is going on? When it should be ON and when OFF, is it possible to make it allways on? Blue backlight, looks cool and it would be quite easier to find elements while driving at night...now I'm poking like a at HVAC and Radio at night as blind man

Please do help me fellow Aveo lovers, cheers, looking for answer!
