it seems like the moment i get into my car and drive the car gets fogged up inside, how can i prevent this from happening? is there any special kind of windows cleaners for this??

 

This might sound stupid, but try small amount of the bar soap on the window. If you think this is a joke, try in your bathroom first. =)

 

Make sure that the ACC is set to "Auto". The moisture should disappear within a few seconds. If the windows are really steamed up, push the defrost button.

 

Exactly. Worked for me every time.

 

Agree! In all cars use the ac as it dehumidifies the air, and make sure your ac is not on recirculate as it just moves moist air around.

 

You can also set AC on and have the heater running, if you are in winter state.

 

I never use the Auto setting in the cooler months (because it DOES run the A/C) and only in the summer when I want to use the A/C and I never have a problem with interior window fogging. Although I do run the A/C in the off months periodically (like this afternoon) to keep the seals lubricated.

Make sure you do not have the recirculate button on. This is the primary reason for this problem.

 

Stop fooling around in the back seat. That will keep the windows from steaming up.

 

lol i was thinking of the same thing, because mine get pretty... umm foggy... no no im just a worried driver making sure no one will hit my car while driving.

 

Rain-X anti-fog, this will prevent initial fogging, your defroster will do the rest.

 

I tried the Stoner Invisible Glass to clean the window thinking clean windows will reduce fog, but I was wrong.

I'm going to try Rain-X anti-fog and Rain-X Glass Treatment.

 

Duh. Turn on the AC.

 

That's probably my only gripe with honda. They don't use variable speed clutches on their A/C compressors, like GM does with their climate control systems. That way you can run the A/C at "low speed" for dehumidifcation purposes.... It also works amazingly well at maintaining constant temperatures without going back and forth between heating and cooling. (and keeps the seals healthy too).

 

I agree

 

so turning the circulate button on is bad?

i just dont want the air from outside to come into the car, so i have that button on all the time

i do turn the AC on when it gets fog up but i dont want to have to do that, i want to prevent fogging from happning in the first place

 

Speaking of foggy windows, I had something rather strange happen on a recent trip. I'd been driving for several hours on an interstate highway. Outside temp was in the 50s according to the TL. I'm driving along just fine. It's overcast, but not raining. The roads are dry. All of a sudden every exterior glass surface on the car fogged up. I mean, one second every thing is clear, the next the windshield is fogged, the rear window is fogged, the outside mirrors are fogged. The side windows fogged a bit, but not nearly like the others. And it was all on the outside surfaces. I had to turn on the wipers, the rear defogger, and the outside mirror defoggers. It was as if I'd driven through a very humid patch of air that was 20 degrees warmer than the exterior of the car. I've never seen anything like that before. At first I wondered if somebody up ahead had blown a pressure hose and sprayed some kind of refrigerant all over the place, but when I noticed the side mirrors also heavily fogged I knew that couldn't be the case. Has anyone else ever had this happen? I'm sure it's nothing to do with the TL; just a really weird occurrence.

 

To AnitN01iLLeR;

There's your problem. Stop using the recirculate and your problem is solved. Read your owner's manual. Every car I've owned for the last many years has warned against this.


To P47ch;

That's probably exactly what happened along with a sudden change in outside temperature. This has happened to me on occasion as well. Doesn't make any difference which car you have.

 

Your gonna laugh... but put shaving cream on the windows. Try it next time you take a shower.... Mirror will not fog up...

 

Not only is this the cause of your windows fogging up, it also prevents the air in your car from refreshing. People are warned not to do this because fatigue and drowsiness may become a factor because you are not letting the old air out and the new air in. I don't know if anybody ever did a study to determine the change in CO2 levels vs. O2. But that is the theory.

 

If the recirculate is always activated, including when the car is turned off, eventually the air inside starts to smell stale. I had a friend who always left his recirculate on, and even worse, he was a smoker. Couldn't ride in his car after a while. The reason that happens is that the outside air inlets are closed when recirculate is activated.

 

ok i guess i'll change that from now on,

the reason i always have it on is because in NYC theres a lot of poplution, bad air coming from trucks and buses and when that air gets into my car i just get that nasty feeling, i guess i'll change that from now on and see how it goes

 

y does it cause fogging up??? because i always go 2 the inside air rather than outside air....

 

FWIW, car manufacturers are not that dumb. If you take apart the circulation system, you'll notice the inside-air/butterfly valve is smaller than the chamber, such that even if you have it on circulate, you'll still get some outside air. The warning is only when the car is not in motion, as then there wouldn't be much outside air coming in on recirculate. At least that's how GM does it, Honda/Acura may be different.

I've used Rain-X anti-fog before. It works great where you apply it, but than every surface where you didn't use it, will fog over twice as thick. At least that's my experience. I also always keep it on recirculate with A/C, and it stays fog free (without using anti-fog).

 

so i should have the circulate on ONLY when i have the AC on?


what about when i have the heat on??

 

yea foggy windows piss me off. sometimes after wrestling practice i'm sweaty as shit and i get in my car and it is nice and cool (winter). but then my damn windows start fogging up and i have to turn on the heat. then i start to get hot, so i open up my windows. then i get on the highway and the windows are loud as shit and i cant hear my music. so i crank up my music. its all a chain reaction that leads to my road rage :angry:

 

To Acuraluvr;

Because the fresh air balances the humidty levels. If you leave the setting in recirculate, this can't take place.


To To AnitN01iLLeR;

No, you should never use the recirculate as the "normal" setting for A/C or heat. It's sole purpose is for avoiding offensive odors from outside (a road kill skunk coming up) or for a quick cooling of the car's interior on hot days. Otherwise, you should always use the outside air setting.

As for cutting out the city smells, consider taping or stapling one of those car scent things you can get for the rear view mirror to the in-cabin filter. This may be all you need. In the extreme, move out of New York.


To gingerbread;

For your situation, try using the MODE switch or the Auto setting and some A/C to ward off the onset of fogging due to your elevated body heat. Your problem is much like having a car full of people in the winter. Doing this should take care of the problem.

 

Personally, I just leave the A/C on regardless if I have it on inside or outside air.

Personally I always get irritated when I go out with people that refuse to turn the A/C on, because it's "cool" outside. Nevermind it's 90+% humidity outside, or we have a car-full of sweaty bodies in the car.

I get even more irritated at those that turn the A/C on for a few minutes, than shut if off again until it gets uncomfortable again, (which in most cases is in 5 minutes... But they don't feel that way, and wait till it gets extremely uncomfortable). Usually these people lock the windows too, so you can't roll down the windows either. Maybe my friends/relatives are just uptight...

 

I am not sure how or why I found this posting, but I have to tell you that avs007's comments are freaking great! Those of you who think that you get better fuel economy with the A/C off may want to reconsider. I've seen enough postings and tests on the net where people did calculations with the A/C on and A/C off where there was little or no difference in fuel economy. If you own a TL and/or drink Starbucks for instance, then you can certainly afford the minute cost (assuming it exists) for comfort.

And you Europeans, New Englanders and Canadians who don't run the A/C or even own one...get bent. A/C is one of the best inventions of all times. I was in plenty of places in Germany and France where the climate is similar to the Midwest or Southeastern US and they didn't have A/C in widespread use. It was pretty unbearable. Remember when there was like an entire 2 month period where France had 90/100+ temps everyday and people were dying left and right? People willing to put up with discomfort because "it's only for a small part of the year" are ridiculous. Dewpoint/Humidity are the name of the game, and it's elevated enough of the time to justify nearly everyone to have A/C.

Technology exists for a reason. Dr. John Gorrie and Willis Haviland Carrier...we all owe you one!

 

stop having sex in the back seat.

 

lol WOW, old thread bought back to life

and no i dont have sex in the back seat, i have a house, a room and a bed for that or other places, but no on in the back seat lol

 

I often run with the AC off, when its cool and dry outside.
It never goes off when in recirculate, otherwise it gets nasty in the car.

I would think you could get away with recirculate most of the time as long as the ac is on. Maybe not with 4 people in the car though...


AC systems use more power, power to turn the compressor, power to run the electric fan (radiator), and it takes power and more gas.

If you run with the ac off and the windows up, you save gas.
If you run with the ac off and the windows down, its about the same as with AC on and the windows up at 60 mph, just lots noisier...

Wind drag from open windows is high...

b/c of the alcohol...

 

Thank you. I couldn't have stated it better myself. It's rarely cool and dry in the US during the months of May-September. There are exceptions, but not many. From having driven my TL in the cold (A/C off) and heat, I can tell you the supposed fuel savings aren't really noticeable. To top it all off, people complain about noise without the windows even open, so once again...assuming that you do pay to run the A/C, the cost is nominal and comfort is a hell of a lot more important than the theoretical(?) fuel savings. If you wanna save money, stop buying Starbucks and get gas station coffee. Better yet, don't buy a car that requires Premium fuel.

 

Well said... I must have a tree that grows money in my backyard than... Cause I drive with all the windows down, the sunroof open, and the A/C on
