Hi, talking facelift elite here.
I understand the outside temp sensor, coolant sensor and sun sensor play a part in dertimining what the cc needs to be doing, but as facelift has no sampler fan how does it get feedback to know its achieved its goals?
Question arises as today I was parked ticking over facing bright sun and feeling cold. Outside temp read 7deg, inside set to 21deg as usual and there's cold air coming through the vents. Increase the required temp and warm air follows. (Drivers side at least, passenger side is normally cold and I guess needs an upside down looking at).

Apart from the cold air in your face, could the cabin temperature otherwise have been at 21 degrees already?

I have no idea, but I can't get my feet warm. :-[

Just to clarify: if that nice warm sun streaming into the car was telling the sensor that you were already at 21 degrees, the CC would not feel the need to give you more warmth. The fact that you DO get warmth when you increase the setting tends to confirm this?

Thanks for the replies Big Ron - I think i'm getting the picture. There is no feedback on the facelift.
In 'Auto' the cc will operate to a certain profile based on sun, ext temp and drivers requirements with no heed to what is actually being experienced by the occupants.
If that don't suit, such as when the occupants regularly change from skinny young neice on her way to ballet to the complete Harpenden front five of twenty years ago, switch to manual control.
At least when I'm trying to fix the cold air passenger side issue I wont be looking for themistor bulbs or such like to clean :y

There is a cabin temperature sensor also.

And almost every duct has a temp sensor in as well.

i put a stick on thermometer in my cabin. the cabin temperature is almost never the same as the cc set temperature - it can be higher or lower even after a long journey. my conclusion is that the temperature set on the cc bears very little relation to the cabin temperature, the cc seems to set the temperature of the air through the vents rather than that inside the cabin.

That makes sense...
Given that its temperature sensors are in the vents ::)

About face.. I've gone from no feedback to cabin sensor (where that then) and duct sensors.. :D
So I might find something to clean the dust off.

not really 'climate control' more 'wind control' then...

Wind being a climatic side effect...

If you have diagnostic available plug in and you can view all the temps in realtime and see if anything is amiss :y
