Why is there more frost on the bottom of windows?

Answer 1

1- you breathe too heavy. 2-You don't have the defroster on. 3-your heater core is leaking Best guesses of top of my head. It would be nice to know what you have, since all cars aren't created equal.

I am just thinking about it.....it just might be the THERMOSTAT....If you have luke warm air blowing thru the vents when you are standing still and then get a blast of waarm air when you start to move (that warmth is coming from the engine).

Check the 'STAT, every 24 months.....

I just had this happen, and I remember from other times.....

good luck

I have that problem sometimes, too. In winter you should have the Fresh Air switch set to receive air from outside the car. Otherwise you are just recycling the moist air you are breathing inside the car, contributing to the buildup of fog on the windows.

Some cars are worse then others with fogging. I know all the Toyotas I've owned no matter what the age(assuming that when they were brand new they had no other problem causing the fogging) have always been horrible with windows fogging up. My brother seems to mostly buy Hondas and he doesn't seem to have much of a fogging problem.

I usually keep the window cracked a bit in the winter. That seems to help more then anything else.

O.K...., Let's see, here... The human body is a nice, warm 98.6 degrees F; The outside temperature is below, say, 40 degrees F; Hmmm... Do you think it could be caused by the same principle that makes 'smoke' come out of your mouth when you breathe out in frigid weather?! Or, maybe it's the same principle that allows you to breathe on a piece of glass and briefly 'write' on it with your finger. Wow! What a concept!

Answer 2

If you are on a properly heated bus the temperature outside of the bus will be signifigantly less than that of inside the bus. Because it is cold outside the window will also be cold. When the warm air inside the bus touches the cold window it cools and condenses on the window into liquid water.

Answer 3

Most of the time when it is cold outside the car and warm inside the car that will happen. It's an affect when the heat and cold come into contact with one another. Test this when your inside your car. Breathe on the glass and it will frost up. ----

Answer 4

When the person or people park the car up for the night, the residual heat from the Passengers or the vehicles Heater, this warm air Condenses as the outside and Inside of the car cool down thus producing Condensation, which then goes on to Freez...

Answer 5

Frost forms on the bottom of windows because cold air settles at the lowest point, causing condensation to freeze there. The bottom part of windows is typically cooler than the top due to heat loss through the glass, making it more prone to frost formation.

Answer 6

The temperature of the glass is lower than the dew point for the air in the room so water vapor condenses on the glass and then crystallizes as it freezes, forming fractal-like patterns.

Answer 7

relative humidity and temperature

Answer 8

Cold air sinks, warm air rises
