Wind deflectors

[Cbatoday]

Thinking of ordering a set of climair wind deflectors for the 2019 sports tourer.

Do these make a lot of difference to noise and rain getting in to help combat a steamed up car

Just put a couple of silica gel bags under your seats. This will cut down, if not stop, the car steaming up.

... and remember that air-con in the Winter helps... especially the windscreen.

[Cbatoday]

Noticed when I do use the Aircon on the windscreen it leaves a film on the screen and this seems to give the condensation somewhere to stick to.

May try the silca bag idea

There are at least two threads in the forum about wind deflectors.

it sounds like the inside of your window screen needs a good clean. When the screen is clean the moisture won’t attach to it. If this is worse when the ac is on then your ac is faulty, it’s job is to cool the air and in the process it removes the moisture.

Another possibility, sometimes after having to put the air recirculating on due to heavy diesel fumes from buses etc , or cannabis fumes from cars full of gentleman of a bohemian persuasion in front.

I occasionally forget to switch it back to fresh air, and if it's raining or damp it soon steams up.

I bought a set of 4 heko wind deflectors from eBay easy to fit and do what their meant to £39.99

"I occasionally forget to switch it back to fresh air, and if it's raining or damp it soon steams up."

Please excuse my ignorance of the topic in hand, but what does the above advice/statement actually entail/mean. I ask because I have a similar problem, (2012. Avensis T-Spirit 2.0 lLtr Diesel) misting without using Air Conditioning. Does it mean , "you forget to turn Air Conditioning off ."  If so I always turn my AC off after the screen clears, but then the screen mists up again.

Many thanks and Regards, John

I would suggest it refers to the air recirculation left on.

i.e., no fresh air coming in... 

[Rhymes with Paris]

Yes JARC1 ,it is as PCM suggests.

With air con off , and the airflow switched to recirculating.

Usually by my mistake, forgetting to return it to fresh air from the intakes.

When this happens, I usually drop a window an inch or so, and make sure the fresh air intake is open.

As others have said Aircon on will tend to dry the air also.

Please feel free to ask again if you are not sure, I am not very good at explaining tech stuff.🙂

This now makes a bit of sense. This old Dinosaur (72 years young) had the idea in his head that having re-circulation on would be the best as it would not be having to cool (or heat) air from the outside and therefore would make use of AC lesser and lead to fuel saving.

Bring back cars that I used to run, understand, maintain and develop , the likes of Nissan 200`s (S12, S13, S14) , Nissan Skyline (R33 and R34). 

Many thanks and Regards, John

Aye John I too am an old dinosaur, not very far behind you.🦴

I don't think that there are many conditions when it's better to have the airflow on recirculate, maybe with a few exceptions with up to the minute auto climate control, that I do not understand.

As it implies from the name, it is recirculating the same air that is already in the cabin, which can be damp,stale or even laden with diesel fumes if I don't switch it to that quickly enough when first smelling something.

So unless the car is sucking in fumes and smells like those,or even when passing a pig 🐷 farm I keep the fresh air coming in, which is then changed often by it going out the rear vents and being replaced by the incoming,AFAIK.

So that's what I know,or think I know 😉 about airflow.

Re the Aircon:

There are different schools of thought on here about whether it is better to run the Aircon all the time or not.

I don't know myself, but I do make sure that I run it often, even in winter,on hot of course,as it makes sense to me that anything electromechanical does not benefit from lack of use.

ie ,a new compressor on the Aircon would maybe exceed the value of my car, whereas say 50p if that,a week in petrol to keep it working seems a bargain.

Interestingly, my car before this one was a 2012 Honda CRV 2.2 DSL, with fancy dual zone climate control as opposed to simply Aircon like my Yaris, it's default was climate control on at all times,as in I had to switch it off to override that.

Thanks very much. I will heed your advice/opinion and go with Air Conditioning running virtually at all times.

I also find having the AC on is almost essential in winter if you're using recirc - The windows steam up really quickly otherwise!

I don't think wind deflectors would make that much difference unless you're having the windows slightly open which will allow the humid air to exit the car and stop the fogging.

That would make the inside of the car really cold in winter though!!

 

[Georgey Porgey]

I enjoy having them is when your driving & it's raining & can open the windows just under the wind deflectors to let some fresh air in.

Each to there own but I always preferred them on my car's.

Swinging the lantern here a bit,as in telling old stories.

A workmate back in the 1970s had a Rover 90, bit of a banger then, the passenger side inside of the windscreen was covered in scratches.

He reckoned that the first owner had a few quid and the scratches were due to the owner's wife/gf/mistress rubbing condensation from the windscreen with the back of her hand while wearing diamond rings,no aircon then apart from American early systems I think.

Possibly true, but the old rover did have a velvet lined tool tray below the glovebox complete with chromed tools, very nice.

I would like some of those wind deflectors now though I think, precisely to have a window cracked open in winter with the heating on for moving airflow, as the rain does spatter the door switches when I do this without them.

Sorry Georgey, I was composing my post while yours was already on , so yes, what you said.

[Cyker]

I did have wind deflectors on the Mk2 and I must admit being able to open them a bit while it's raining is very nice. Even being parked, it was nice being able to open the windows a bit without 4 tons of leaves and twigs being blown in

With my Mk4, if I open the windows even 1mm when it's raining, somehow all the rain still gets into the car!!!  

I tend to rely on the HVAC for all ventilation tho' as you generally don't want the windows open, even a little, when stuck in London traffic unless you really like breathing in diesel bus fumes!  

I do miss having a sunroof in summer - That was one of the best things in the Mk1 - Turn on AC, tilt sunroof. Car cooled down so quickly!

Ah yes, I was forgetting about the sunroof on the Mk1 , lovely bit of kit, works very smoothly and is completely watertight on this one.

Diesel bus fumes eh ? I had assumed that those futuristic looking new London buses were powered by nuclear fusion or some kind of magical pollution free source like lots of AA batteries, given the current obsession with saving the planet from global warming, apart from when it's cooling.😄

But yes, diesel fumes are not pleasant when following a badly maintained bus or other belching black smoke,in spite of them being in theory illegal now, there must be a "special" test for emissions that allows this.

 

[Cyker]

They keep saying they're phasing them out but I still see plenty of diesel buses and black cabs floating around London. Usually next to or in front of me!  

It is a sore point for me after being KHAAAAN'd and ULEZ'd that these rules apparently don't apply to public transport when they should be leading by example!

To be fair, for the first time I saw an electric bus so maybe it is finally happening! (Well either that or they just stuck a green sticker to the side of the number plate  )

"there must be a "special" test for emissions that allows this."

Yes, It`s called London Transport Vehicle Test Stations.
