One one of the coldest days of the year this morning for the whole drive to work I could not get the fan/heating to work, tried auto, manual, rapid defrost etc... nothing. I had a misty windscreen and it was bloody freezing, reading 1 degree inside! Got to work, switched off the ignition, restarted it, all of a sudden fan starts up and all is OK.

Anyone else have this problem? Hope its not an intermittent fault which will reappear in winter.

Otherwise I've had my Giulietta for a couple of months now and I'm really very pleased with it. Looks fantastic, goes really well and I get lots of compliments about it. I've already managed to kerb one of the 18" wheels thoughs, the first time in 10 years of driving - they are very exposed with no rim protection on the stock tyres whatsoever! I could have cried, not had it repaired yet, will wait until after winter.

Climate control will not start blowing out air unless the engine is warmed up enough so the temp. requirement can be met.

But in the case of rapid defrost it should start regardless. How long did you keep trying the above? Did the engine come up to temperature?

Thanks for the reply

I tried for the whole journey - about 30 minutes or so, the engine would easily have warmed up. I know when climate control is set to auto it only starts blowing when the engine reaches temparature, this is normally 5 mins into my journey, but with rapid defrost all the lights came on but no fan. This should work straight away, if not it's a fat lot of good if you're trying to defrost your windows in winter!

Despite its quirks I still love this car!

ditto - had to warm diesel 170 JTDm on drive for 5 mins to get it to blow hot even with "demist" buttons pushed
QV takes about 3 mins, probably as engine block is smaller and heats faster
Either way, I find a kettle full of cold water clears the mist and the blowers keep it clear
Note that: not risking windscreen cracks with warm water ...

Same here, demist button does nothing when cold, which sort of defeats the object, had to use auto instead but still took ages to clear...

Glad it's not just me...demist does nothing for me in cold morning either. I override auto by pushing the up arrow then dial in '11' on the fan speed. Not a clever design really! But I do enjoy how the heated mirrors come on with heated rear windscreen!

The HI position on my 147 did the same, Didn't blow until there was some heat in the engine.
On my G i press the fast demist and then turn the fan up. By the time i have done about 1/4 of a mile there is some heat in my engine & i press the auto and the fan works ok from then on.

It's about time heated front screens were made available even as an extra cost item.

There is no point in blowing in air that is no warmer than the outside air. That's why the CC will not start as soon as you want it to!
And when the temp. is many degrees below 0 C..misting of the windows is not an issue usually so the trouble zone is a small margin. :rolleyes:

In the OP's case it read to me that it wasn't just that the car took a long time to warm up & de-mist, but that the fan refused to start-up regardless of how warm the engine was, until they switched off & restarted the engine :confused: Is the climate control also developed in partnership with Microsoft i wonder?! (switch-off & re-start) ;)

I believe knowone can offer them as Ford put a patent on the design with its QuickClear windscreens. I'd have thought by now someone should've stepped in & told them where to stick the patent, seems quite bizzare to me. Maybe Fiat should've negotiated use of the design as part of its tie-up with Ford for the KA/500 :cool:

Cheers for all the useful comments,

This morning the same thing happened with the rapid demist setting, but turning to auto or manual and turning the dial resulted in the fan working, which I set to full blast. Yesterday I had nothing whatsoever no matter what I did, lights came on but no fan on any setting.

Interesting that the rapid demist only works when the engine temp rises, its logical, but kind of defeats the point. What's the purpose of the 'additional heater' then which is included on the spec for the diesel engined cars? I thought this was to send warm air into the cabin whilst the diesel engine was taking time to warm up.

Now that I come to think of it you might be right, the old Micro$oft trick of turning it off and on again seemed to cure it! :lol:

That used to be the case, but i believe the patent ran out a couple of years back.
The Vectra-C BTCC car has a heated windscreen option and costs £2000.
I have heard that you can order them on Volkswagen group cars too - VW Passat, some Skoda's etc and also Volvo's.
Some screen manufacturers will do special orders for a minimum order of about 10.

I've got a company Transit and it's got a heated windscreen, fantastic but only Ford seem to have them, generally. Took about 10 minutes to clear the windscreen on the G today, don't they have cold weather in the Alps?

I thought the Additional Heater was meant to do what you describe; provide heat for the period whilst the engine is still warming up. Clearly if they really are fitted to the diesels, they don't work. Unless anyone can confirm that their (UK) diesel cars provide instant heat? I wonder if this additional heater is just fitted to cars for colder climates & the literature in the UK is incorrect.

Now that I come to think of it you might be right, the old Micro$oft trick of turning it off and on again seemed to cure it! :lol:
Most electrical related faults on Italian cars follow the Microsoft principle. If in doubt, switch it off & back on. If the fault comes back, then there might REALLY be a problem ;)

I thought Patents were time-limited, that's why i couldn't understand why heated front screens are so rare. I wouldn't pay 2 grand for one, no way, but if Alfa have the know-how to heat the wiper area, i'd have thought they could do the whole screen. I'd be very grateful of it as Fiat/Alfa diesels do seem to be some of the slowest engines to warm up. My Stilo JTD, like the Punto JTD before it, takes a good 5 miles at 50mph+ to get upto opperating temp. I suspect the current JTDm's are more or less the same.

Yeah go Ford. as much as it erks me to say it. I had 95 MK6 escort with heated windscreen, bloomin marvelous untill a few of the elements go and you get stripes of fog ( yeah you guessed it .. in all the wrong places)
I thought it was a standard until I start looking at a new (nearly new) vehicle .. still ... it all comes out it the wash in my experience, you have a choice .... the upside inviolves RUST .. plenty of RUST

On re reading ... £2000 .. reallly .. £2000 ... REALLY.... that was half the price I PAID for my 1.8 saloon 95 ford .. in ohh 98-99 ish .. sounds like the heated windscreen was kinda worth it ... even with the stripe down the middle of the drivers side after 5 years ... no I'm not kidding.

Modern Diesel engines don't get hot enough to generate enough heat to warm the cabin, so a supplementary electric heater needs to be used too. On a petrol engine, the waste heat of the engine is sufficient to warm the incoming air.

The additional header will not make the Diesel car warmer than the equivalent petrol model.

If the auto system tries to use air con under certain cold temps it will not work & I always try not to use the heater when cold in any situation as the heater takes the hot water from below the thermostat it has a major effect on the engines warming up time.
