We have a Land Discovery Sport 2016 diesel and an air conditioning control button is turned off, it works normally. Contact an authorized workshop. They informed me that just changing the entire electronic board to get the lighting on this button back, would there be another alternative? or LED that can be replaced?

 

Did you find a solution? Mine aren't lit up either and I didn't know if it was just the way that it was made or if it could be fixed. I do know that it's rather annoying and would love to be able to see my buttons at night lol

 

Have similar issue - no lights on the physical buttons for ventilation controls, for example recirculation and vent selection. My guess is there is a bad semiconductor (diode, capacitor, etc.) on the circuit board. It's not like the old days when you can just change a bulb.
