I was on the road this morning quite early. Pure Temp. technically so for me in the not air conditioning area. So air conditioning on Econ and gets. After a while about half an hour comes cold air at once. Air conditioning runs. In the menu looked, but that was still on Econ. I pressed on it twice and was good. about 5 min later the climate starts again and cools down powerfully. So it went on and on until I finally was at the finish and the car turned off My question: (GMD user as expert) If I switch the menu AC to Econ, the climate should be out and also stay out. Why does the stupid thing jump on again and again without my intervention ?? is that normal or a defect ?
