Winshield moisture

[candy_jai]

After leaving my Yaris sitting under the snow for about a week, I noticed that the windshield was wet on the inside. It seems that moisture has been getting in. I know all the windows were shut. Should I bring it in to check for leaks or is it because the vent is left in the fresh air position and letting moisture in? It doesn't do that when I leave it out when it's raining.

Same reason a cold water glass gets wet on the outside...... condensation.

When you get into a car your feet carry in snow and you carry in moisture..... you breathing does it too but not breathing is out of the question!

It is not a problem....... use your defroster on full and even after the window is clearded off ....keep the defroster on. You want to use it to remove the moisture from the car. Make sure the air vent is set to intake and NOT re-circulate or you will have even bigger moisture problems.

It's normal.

Well the weather in vancouver has been in the negatives during the end of dec til the first weeks of jan. I havent touched my car in like a week and it was burried under the snow. It was only just last weekend that I got in and turned on the engine to warm up and noticed that water droplets were formed inside while it was sitting there for a week. I had to use something to wipe it as it will take forever to dry up using the vents + a/c at full blast.

So my main concerned was how did moisture get in when I havent used it for a week? It could possibly be the mats were abit wet but as bob_vt said, probably nothing to worry about.

...condensation...
you(r) breathing does it too but not breathing is out of the question!
Unfortunately, I know a few too many people who stopped breathing last year :frown: I happens to the best and worst of us - but hopefully not behind the wheel of the Yaris:wink:


+1 on the condensation

even if you have not gotten into your car for several days, the warmer air inside of the car is attempting to travel through the medium with the least resistance...glass in this case. since the warm air is escaping, it is attempting to bring with it the moisture it contains, the warm air escapes leaving only the moisture behind.

snow on the floor of the car will evaporate into the air and condense where its the coldest....in this case, your windsheild w/ snow on it

it happens...dont worry so much

[candy_jai]

alright! thanks guys for your input!

yeah.... changes in temp do this... but it seems the yaris is more prone to this than some other cars.... My 626 seemed to be more resistant... maybe thats because it had a bigger cabin... i dunno.

Gee, for all these years, I thought glass was a vapour barrier:rolleyes:
