I have a 2003 bmw ix. The heat and ac are on at the same time. Heat from defrost and floor, a.c. from dash vents. Seems to be a mixing problem, any ideas
Sounds normal to me. Put the white line of the slider in the middle of the two dash vents and push Auto on the climate control. The AC will kick in, you need this to take moisture out of the air. Adjust the temp to your liking, I put mine at 68 degrees. the vehicle will adjust the cool or warm air automatically. When the heat kicks in, it's more on the floor, where cooler air comes out the middle vents to keep the driver alert. It take some getting used to if you never owned a BMW., and it's different from other manufacturers.
