Condensation on the inside windows. I hate it. How do I get rid of it?
What's the cause of it? Why does it take so long to remove with the
defroster? How can I seal up the outside of my car. What's the best way to
I run my AC briefly to get rid of it.
Not sure if sealing your car would help, if that were possible.
Remember that condensation is due to the humidity in the air and your
car would still contain air, even if sealed.
Yep. That, and tell your passengers to stop breathing.
BTW, while there are products out there that are sold specifically to
curtail condensation, a bottle of windex and some newspaper works very
Just Newspaper on it's own does a fair job, without smears if the
windows are only a little grubby on the inside too. And you can dry a
slightly damp window with Newspaper and clean it at the same time.
One tip, alcohol based de-icers for the outside of glass can actually
cause misting on the inside because they change temperature so quickly
the condensation forms from moisture in the car. You'll get less
condensation if the glass is scraped without de-icer (unless it is so
hard you can't shift it).

As others have and will state, the A/C must be run with the defroster (your
A/C -is- operational, isn't it?). Also, that YOU are in the car ....
BREATHING ... contributes significantly to condensation on your windows. If
you get into the car with WET wearing wet clothing, this too contributes to
If your vehicle is equipped with a manual 'recirc mode' and you
are operating your heating system in the 'recirc mode,' that's
likely your problem. If not, check for a heater core leak
Sealing up your car will only make things worse - unless of
course you don't have the need to breath. The moisture in
your will condense on the windows. How cold is you climate?
Running the A/C while heating will remove a lot of moisture.
Unfortunately most A/C systems don't run once the
temperature drops below 40 degrees Fahrenheit. Avoid using
the recirculate setting. This just allows moisture to build
up in the car.
I don't believe this holds true for automotive systems. On my old
Pontiac the A/C was directly tied to the defroster setting--switch the
system to defrost, and the A/C was activated. Good way to keep the
compressor oils circulating to keep the seals lubricated, in addition to
removing condensation. Worked at any temp, as I recall, and I move
around NY/New England.
I'll confirm this on my new 94 Civic in a few days, as it has now gotten
cold enough around here to check. Disabling it below 40 degrees would be
idiocy--it's the only way to remove condensation effectively. It is
true, however, that many room A/Cs don't function when the outside temp
is "too low"--which occasionally annoys me.
The deactivation on newer domestic and automotive AC's, at 40
degrees, is a federal regulation intended to save energy. Same
as the limit on water capacity for toilets and the latest washing
machines sold in the US. Your government at work. ;)

AC systems have always had low temp cutouts on them, and it's not idiocy for
the above poster. The ac is called for anytime the defrost is selected on
most cars but is prevented from cutting in below 40 F because below that
temp the gaseous refrigerant will liquefy and as we all know you can not
compress a liquid. It cuts it out so that your compressor doesn't smash to
little bits trying to compress liquid refrigerant.
Short lesson in refrigeration, compressor draws in low pressure gas, pumps
out high pressure gas. High pressure gas condenses into a liquid under
pressure in... what else but the condenser (that other rad in the front of
your car). High pressure liquid is metered/sprayed into the evaporator
where it becomes a low pressure gas again and so on.
For the OP, cars with persistant high humidity situations sometimes have
water leaks that may not be apparent. I had a Supra that leaked water at
the hatch. Windows seemed to fog easily. Discovered one day that the spare
tire well was half full of water.
You certainly are entitle to your own opinion. The AC on my 83
Continental will run below 40 degrees but not my 2005 Lincoln LS
or my 2003 Mustang GT. Go try a buy a three gallon toilet or a
new model top loading washing machine in the US today. ;)
