Aircon as demister - H.F. Smith
Aircon acts as a splendid demister but, in the winter, one wants a warm interior. My Punto has a basic system (i.e. not "climate control") and seems to have no thermostat, so is there any objection to running the aircon while the heater is also on?
Re: Aircon as demister - John Slaughter
None at all - set the temp to max, with the aircon on and it'll demist in no time!

Regards

John
Re: Aircon as demister - Darcy Kitchin
On basic systems e.g. as fitted to my old BX, the aircon starts cooling before the heater gets hot so, purely for my preference, I wait until I can see a reading on the temp. gauge before switching on the air con. Also (see previous posts on this), the load on the cold engine sometimes stalls it before the ecu wakes up to falling revs.

Not at all, it works fine on old Celica Supra.

Standard practice down here in Ozland, but we don't have problems with cold engine stalling. It's the benefit of a nice big (4 litre) engine and relatively cheap fuel, 'cooking' petrol is 29p/ltr!
Yes, it does get cold. Now is winter and early mornings are 3 to 5C, but it gets to 20C by lunch time.
