On some cars the aircon is automatically switched on, to dry the air, if
the heater/blower is set to clear the windscreen rather than to
blow/hot/cool air into the passenger space.

No idea but it may be a menu setting (possibly only available with
servicing equipment) rather than a fault.

Makes the car cooler in summer
makes the demister work better in winter

Must use more fuel ultimatly, but I still keep the AC on most of the
time.

My climate system default to on, or rather enabled when the ignition is
cycled. Even when not needed for cooling it can keep the air in the car
drier, than it would be. It is especially useful for clearing a misted
screen in damp weather.

If you leave the heater controls set to "auto" - then you may find it
selects AC as and when it thinks it needs it to meet the requested
temperature, or when demisting is required.

On my current car and the last one, the AC would come on when full belt
demist/defrost was selected, then go off again when you went to normal
heating, if the AC was normally off. AC off is marked ECO.

But a small car may not have as sophisticated a system.

Is it air con or "climate control"?

With a climate control system you just leave it on for
heating/cooling/dehumidification.

Even if it's basic air con I can see it being useful to preserve
the seals. Worst thing you can do with air con is *not* use it
for long periods.

Perhaps its to ensure the AC is used regularly to prevent the common
faults due to seals drying out when AC is not used for months.

Most switch on when you use fast de-frost, etc. Which you almost will do
in the winter months when you may not need to cool the interior. Which
should keep it happy.

Wasn't sure how much of it is servo controlled via a computer. Some do
some very clever things. Like keep the fan slow until the engine heats up
enough to give heat, ramp up the speed until the set temperature is
reached, then ramp down to a quiet speed. Some allow individual control of
either side of the car. And so on.

If it is so it is a dumb design. A/C on in any car takes a fair bit of drive power, the car slows down.
In a car like Nissan Micra which I think is of 1600 or 1400 cc it would mean engine would struggle to move with even an additional passenger on board. I would investigate, make it default A/C +off condition

One possibility and I dont know that car, is that you set the heater to
demist: On mine that automagically puts the aircon on to dry the air.

Depends what you mean by fine. All AC takes quite a bit of power to drive
it and that power has to some from somewhere.

Many blokes would like to do the same , sadly if you have a female partner
they will invariably fiddle in the vain hope that a cold engine will start

I'd guess different makers use the same climate control system - or rather
from the same maker. Rather like engine management. And like all such
things likely comes in different versions according to what the car maker
will pay. Even although a lot of the facilities may actually come at a
very low extra cost, if any.

Yes - I generally leave mine on auto, apart from fast demist/defrost.

I once had a Triumph 1300 that was equipped with a valve arrangement

It was suitably hidden so the passenger(s) would not realise what had

This happens on my fairly ancient Rover. Which has zero automation for the
heating - just the levers of the time.

Apart from the benefit of drying the air, it ensues the AC is used during
the winter to help prevent the compressor seals drying out.

All that says is you are incapable of noticing the difference in
performance and MPG. Or perhaps you think the power to run the compressor

The 'eco' screen on my car's trip computer warns you about stuff that's
burning diesel (windows/sunroof open when travelling at speed,
bum-warmer left on) generally stuff you would struggle not to notice.

It gives an estimate of the energy used by aircon, which seems to hover
between 1/16 and 1/4 gallon/hour, presumably would go much higher in
warmer climes ...

All that says is you are incapable of noticing the difference in
performance and MPG. Or perhaps you think the power to run the compressor
comes from the magic tree.


Fuel consumption increases when the A/C is on but but with modern engine
management the drop off in performance is barely noticeable, unless you
are pushing your engine to the limit.

Thanks for all the helpful replies. Such level of sophistication had
not occurred to me. I will need to explore thoroughly. It's
certainly different to my previous Micra.

Thanks again. This turned out to be the case. When the demist
function is selected the A/C automatically comes on. This possibility
had not occurred to me.
RTFM

I cannot disagree. I don't have the FM as I bought the car second
hand but before you say I know it's on-line and I should have checked.
I was thrown by the previous model that did not work in this way.
Thanks to everyone for keeping me right.

Makes no difference if you have modern engine management or not. Unless
that management deliberately restricts engine output when the AC is not in
use - so the likes of bert can claim it make no difference.

But rather obviously, the less the output of the engine, the more the use
of AC is going to be noticeable. As the energy needed to cool the cabin is
determined by the size of that, not the engine.

Tried that with mine, alas I don't read Japanese!

Maybe pushing my luck here (but I am an opportunist). Any ideas why
the aircon light (and I assume the aircon) on a Nissan MIcra should

If it is so it is a dumb design. A/C on in any car takes a fair bit of
drive power, the car slows down. In a car like Nissan Micra which I
think is of 1600 or 1400 cc it would mean engine would struggle to
move with even an additional passenger on board.

Given that you clearly have no experience, why make stuff up?

I€˜ve driven plenty of small hire cars with A/C that manage just fine,
even with extra passengers.

Depends what you mean by fine. All AC takes quite a bit of power to drive
it and that power has to some from somewhere.

Utter ********.

Are you practising to be TNP?

Takes very little.

That rather depends on the AC system. Some will suck in excess of 10 BHP.

What was that you posted elsewhere about not assuming your experience is
reflective of everyone's?
