why does ac switch on when...

[ryzie]

you put the heating in auto ? when i turn the heating up and put it in auto the ac button lights up same time ? why's that ? will the cabin still heat up or will the air conditioning come on ??

The climate control will heat or cool to the desired temp. Since you live in Gt. Britain, you won't really ever have the need for cool air, so you can probably just turn off the a/c button and run the fan on manual.

The AC is turned on so the air is dried out leaving the cabin condensation free. It's a habit I always use when it's cold outside.

I find this feature very anoying,sometimes I turn the fan speed up or down when in auto mode and no climate on, but to get it back to auto, you have to then switch the climate button off, why won't it let you find the auto setting by just altering the fan speed back to where it was.
