I have a none A/C 320i 1995 August build manual.
The blower when turned to cold still puts out hot air. Like the heater is still half on.
If I turn the heater fully up it gets a lot hotter like it should. But when I turn it to coolest it gets less hoter but it is still blowing out hot air. Its almost like it doesn't shut the hot air flow off completely to allow the the outside cooler air in.
I'm having to shut the blower off completely at the moment which is utter madness in this weather.
Anyone got any ideas what the problem could be?
