Normally when you start the engine the fans(air vents) and climate control start together with the engine or when the ignition is on.
In my case, I need to wait around 1 minute, but not always - usually after a longer stop to a climate system starts and every time my settings (temperature, air flow direction) are reset to default. Even if I press the buttons climate system won't start, only the AUTO button is highlighted. The big display shows FANS OFF. One day I think I could see something like d55 on LCD display where the temperature is shown.
Any suggestions what it could be? I have tried to search somewhere in settings, and even unplugged battery for a minute - no results
