Forgive me if this has been discussed before but I can't remember where but I thought it might have been here. However, my question is, what is the minimum outside temperature below which a car's aircon system won't engage or operate as it would be useful for it to be 'on' when the outside temp. is, say, 0 celsius in order to remove interior condensation. However I'm sure that it won't work under these conditions.

It depends on the make. Some (few) will work as low as zero, others stop at four degrees.

Now I could be wrong, but doesn't the dehumidifying bit of the AC still work regardless of the outside temperature?

I'd be interested to know this as well, and does the compressor kick in for this to be so? If it should, then my A/C is definately in need of some attention, as the car is misting up something chronic recently.

Mine (VW) definitely works when it's around freezing, and very useful it is too, the inside evaporator goes down to -6degC when measured with an infrared thermometer.
It would probably cut out eventually to allow any ice to melt and drain away.

Thanks for that link. I knew that I had read it somewhere but my search criteria of 'aircon' was obviously not accurate enough.

Only when the condenser is below the ambient temperature, therefore if it can get to (say) 3DegC it'll dehumidify until this point (as moisture in the air will condense on it), below that it's just an ornament.

I tried to get the same point across in the other thread IC, but your way of putting it is much more concise :-)
