Why is there condensation on the inside of the windows of my car?

Question

My car always ends up with condensation running down the windows on the inside. Does any body know what causes it and how I can get rid of it?

Answer 1

Haven't you seen Titanic? It happens when you shag inside of it.

Answer 2

Where do you live? Make sure that you have all the windows rolled up, especially on humid days.

Mechnical wise either your air conditioneror heater could be causing a problem.

If you notice this when you've been running the A/C the drain tube that drains the condensation from the system could either be stopped up and backing water up into the passanger compartmen or the drain tube is out of place and draining into the passanger compartment...is the carpert wet in thefront passanger floor?

Do you smell anything kinda sweet or like the radiator overheating then it could be the heater core that is located usually in the passanger side of the dash. Take it to a mechanic and have a pressure test done on the engine cooling system.

Answer 3

When you get into the car and you are wet from rain, you leave water in the car and it evaporates and then condenses on the cold windows. Also your breath is loaded with moisture and this to condenses on the cold windows. Also smaller cars tend to suffer more than larger ones. It's widows open and heater blower on to full for you.

Answer 4

The answer is that either your air conditioner isn't working or you don't have the contoller set to the A/C position. If this is an older car and doesn't have working or have a/c then thats why its just differing temps between outside air and inside air. Part of an air conditioners job is to remove excess moisture in the air, so without it your almost out of luck. I know they sell small chamois here that you can use to wipe the windows off, we have one for our old honda as it does this.

Answer 5

Its when the temperature outside of the car is low enough to change the air vapour inside the car to dew. A good solution is prevent the temp outside of the car from reaching that temp. The best way to do that is to buy a cover for your car and put it on in the evenings before the temp drops.

Answer 6

This is caused when the moisture (humidity) in the air outside is thicker than the humidity inside your car. The best way to clear this up is to make the inside of your car a similar level of humidity to what it is outside. Roll down some windows and it should eventually clear up.

Answer 7

My car used to do that .When we had the heater on .Then parked up for the night .The next time we used the car and switched on the windows misted up the only thing best to do is open your windows a bit it will soon clear up .With your fan on as well.

Answer 8

there must be some damp coming in from somewhere. a cheap way to get rid of the dampness is:
half fill an empty ice cream tub with ordinary table salt and stick it in your boot or in the foot-wells. leave it for a week. you should find that the salt absorbs the moisture and turns the salt rock solid. you might need to repeat it a few times.
good luck!

Answer 9

This usually happens when there is water leaking into the interior of the car from somewhere. Could be rain water leaking through a faulty seal or the heater radiator could be leaking engine coolant into the front footwells.

Answer 10

easy.because your car is warm on the inside and it's cold outside.maybe open a window for a few minutes to let inside cool down before closing up

Answer 11

put your defrost on & put you heat setting in the middle then turn on the heat this should remove it, good luck
