Both the 2004 V70 (165K) and the 2003 XC (115K) do not seem to control
the heat properly. When you start the car the heat control seems to work (set for 68F),but 30 minutes later it is blowing cool air, both sides. If you crank the heat up it will become warm. I have vaccuumed the air sensor inlet ....
no improvement. The AC is set to manually off. Both cars seem to have the same condition.
thx.

    Heater controls V70-XC70

    Never believing the controls, I have been known to stick a 'reliable' thermometer in the car to verify that 68F is actually 68F.

    With the AC off, it cannot get colder than the outside air. If the sun is not hiding behind clouds, the sensor in the forward part of the dash will cause cooler air to come in anticipating solar heat through the windows.

    Is the vent control and blower set to AUTO? If not, do that. The auto will mix upper and lower vents and prevent all of the air coming out of the dash vent.

    As I age, I find that the cabin temps are set higher and higher for my comfort. Currently it is around 74-76F, year round. Without the AC switched on, there is a tendency for the system to get hotter and colder than desired as the ECC expects to have the entire system functioning.
