Windows steaming up?

[cupra300uk]

I have this recurring problem daily, not sure why it’s doing it and how to get rid of it though, unless I use the AC but don’t want to use the AC all the time as that uses more energy from the car which in turn uses more fuel (I think).

Can anyone tell me what I’m doing wrong please?

Heater working ok?

Think so, will try it when I’m next in it. Thought it was the one on the bottom left dial beneath the Cupra button?

From the imageiit looks like that dial is split in two

Top is front
Bottom which is itiis rear

The dial IS split in two. The top portion is the rapid demist of the front screen and the bottom portion is the rear window demister.

So the top bit of the dial does get rid of the steamed up windscreen, however it only works if it’s on the max setting and full power to the blowers, doesn’t work if it’s on any other setting for the blower, as well as it blowing boiling hot air throughout the car.

My old ibiza just had a button to get rid of it all and it sorted it first time

That’s the idea. It’s a RAPID demist which means it turns the fan on full and at the heat you have selected. It shouldn’t need to be on for much time so shouldn’t really blow much heat into the car itself. However you will benefit from it in winter with defrosting the windscreen and warming the car up...as well as those heated seats.

I have mine in auto with Aircon on all the time with temp set at 22degress, in 4yrs I haven't had to re-gas my Aircon and it uses like such a small amount of fuel it's probably cost me 5p to run it

Just leave the Aircon on and your mist problem won't be a problem

I agree with Pew. It's supposed to be better for the AC system to leave it on all the time. Although I usually have temp set to 19 degrees.

I agree with others heated ac will be best for screen. Use the quick demist initially and then I find auto mode in low 20s keeps screen clear

Thanks for all the replies, will leave the AC on all the time then. If my fuel drops rapidly I’ll be billing you all directly

I leave the aircon on all the time for exactly this problem. Apparently when your doing motorway, aircon takes very little extra fuel. It's in traffic it's supposed to make the difference. But I tried it over a week with the aircon off and saved about 2mpg on my daily commute.

However, I've just applied the Gyeon interior anti-fog coating, it's only been on a couple of days so I'll see how it goes. But for £8 might be worth giving it a go (rain-x do one as well which is supposed to be good).

Hmm not too bad then really in the rand scheme of things, I’ve used rain X before so will look into the anti-for stuff

I use one of those demister pads, and it tends to somewhat sort the problem (windows steam up to a lesser extent. However I only have the manual AC, and I just turn the dial to front window, and AC turns on automatically and problem solved for a bit...like 10 mins.

My misses has a 2 year old astra which suffers from bad condensation overnight. It was taking an age to clear windscreen in morning and steamed up easily when driving. I ended up buying her a demist pad to leave in car overnight and it apparently absorbs moisture. It has an indicator to let you know when its full of moisture and needs a blast in the microwave to burn off all excess moisture. It's been a great buy and worked a treat as the car steams up far less now. I'll see if I can find a link for the pad.

Leaving the aircon on doesn't use more fuel in modern decent sized engine. Uses more fuel driving with a window open.

I always used to drive with the Aircon off but then found that whenever I did use it I got that horrible fusty smell because it wasn't being used. It's on all the time now and I don't really notice any difference in mpg.
I had to use one of those foam cleaners with the long straw down the air vents to get the smell out of the car. It was totally rank..... but at least it's sorted now.

My air con has never been off since I picked the car up a year and a half ago. I still get misting overnight but not whilst driving.

I have one of the demister pouch things noted above but can't say I've noticed it actually doing anything tbh. Even tried leaving it on the dash and the windscreen still mists up over night. Not been too bad yet as it's still reasonably warm but as soon as the temp drops the mist starts.
