Model 3 Long-range AWD.
Upon entering the car after a day it was not driven, the air conditioning system begins heating vigorously, even though the temp control is set to 20 deg-C and the weather outside is quite warm. It doesn't then respond to temp control at all. It returns to normal only after driving for a while, or after sliding the temp control all the way down to the "Low" position. (I can't distinguish between the two causes because both occurred at the same time.)
Please advice, thank you.
