[CL9] Windows fogging up outside

[3RotaRX]

Hi ozhonda members

After driving home yesterday in rainy wet weather, my windshield would fog up from the outside and inside the cabin the windows seem to be clear. I know this because when im using my wipers and the fog goes away and comes back again in a few seconds. I tried all the buttons like having the A/C on but still cant clear the fog from the outside.
Help please

Hav u try putting heater on & blow the windscreen to warm your window up? It could be just cold & wet outside & water condense

Did you try front/rear demister? not sure in cl9, but its in cu2

[3RotaRX]

yep, i've tried putting on heater and its still happening :(

I have tried the front demister and it only clears inside part of the glass and not the outside.. The rears dont really get fogged up so i never tried.

Its becoming dangerous to drive as i cant really see when im driving in the rain, i'll probably have it get checked out by honda or something if i cant think of anything else to do.

it's fogging up because the windscreen is too cold.

the cold windscreen is condensing the water vapour on the outside.

turn off your A/C

Try and give the windscreen glass a proper hand wash [not just using wipers] as it may be road grime thats contributing and making it worse

Ok, ill give it a try tmr, thanks.

People with similar problems said that the culprit might be rain-x, some also suggested to use Halfords Intensive Glass Cutter along with a microfibre towel to give it a through clean.

Hi All,

Not sure if this is related but I am having issues with trying to get rid of an imprint of a decal on the windscreen. Everytime the front windscreen fogs up, I can see where the decal was and what it said. Is there anything I can use to remove this as this is extremely annoying!

Thanks

You'll need to use a clay bar or the product mentioned above to get all contaminants off the window, then go over it again with hand wash - should clear it up for you...

Gonna have to agree with bludger. I also have a feeling youre not putting the heater on long enough to actually make it work.

Heater or aircon won't do shit for the outside.

[Bludger]

On days with heavy rain, I find using the A/C to defog the inside works, but after a while, it will fog up the outside, because that bottom section of the windscreen is getting too cold.

I try avoid using A/C to defog when i can.

[trism]

A/c on hot or cold will defog inside, because its dry air, it absorbs the condensation.

Secondary effect is fogging up the very bottom of the windscreen when its on cold.

However this shouldn't spread to the entire windscreen, and it is easily removed with the wipers.

cold windshield will fog up like how a cold bottle will appear to swear.

Try cleaning it and adding rain x. or better still just try keep the temperatures the same

u guys must be having a shit summer

Use the aircon temp setting adjusted to middle for best defogging

Same thing happened with my dad's Corolla. Found the problem only presented itself in a certain setting though. That was to use recirculating air and having air blow onto the windscreen (can't remember other settings, i.e hot or cold, A/C or not) but yeah, get it off recirculating, and on fresh/external air and you should be fine.
