Condensation on the inside of windshield

[Matt]

The last 2 days, after parking outside overnight at my workplace, I've gotten into my car with TONS of moisture on the windshield. I can run my hand across the inside of it and it's enough to drip off my hand.

I've googled it a bit and many replies to these problems are "leaking heater core". However, the carpets were not wet and there was no moisture on top or bottom of the dash area.

Should I be worried about this? I'm 100% the windows were both fully closed, and the doors/trunk were both secure. Is there any other possible reason this is happening? Investigate further or take it to the dealership?

Hopefully I'm just over-reacting.

Hmm, my dealer says it's normal. My girlfriend's car didn't have this amount of moisture on the inside of the windshield this morning and the G35 next to my car at work didn't have this amount of moisture either.

I had some on mine this morning but not enough to worry.

I think I'd be ok with a little bit. In my short 10 years of driving, I've never seen the amount of moisture I've seen the last 2 days. Could it be that my car is just better insulated than my previous cars, thus creating a bigger discrepancy between the outside and inside temps?

If I had to guess, I bet I could of gotten almost a half a cup of water off the windshield this morning.

My Fit does this sometimes in cold weather when temps dramatically change outside.

If you're using defrost mode (or defrost and vent to foot mode), set it to vent from the top vents just before you step out and see if that changes anything. Seems like the heat from the engine seeps into the cabin and remains there causing the condensation. I don't know, give it a shot.

Condensation forms on the warm side of the window. You doing some "heavy-breathing" in there?

Set the system on outside air instead of circulate in the car? I'll try that tonight.

You have your inside air set to circulate rather than bring in outside air? You have something against oxygen, Matt?

I have no idea what it's set to. All I know is I have a shower door for a windshield and I'm being told it's normal!!!!

LOL! I guess the idea is to equalize the temp and humdity inside and outside the car. You'd figure that just opening the darn door would go a long way toward that end.

if you're using defrost you should be using outside air anyways, no?

leave the vent open to the outside air....

Uhhh....Your breathing is filling the car with moist air. Don't use the re-circulate mode unless you absolutely have to.....(like being stuck behind a Hog truck or something..)

Hog truck...hahah, I actually know what you are talking about..Only in the South, brotha!

Remove Window and Windshield Condensation
There are several strategies available for removing window and windshield condensation, some of them targeting condensation's source - temperature discrepancy. You can also purchase solutions from car shops which make the removal of condensation much faster and easier. To give you a clearer view of things, here are some of the strategies for removing windshield condensation:

•Toggle the Air-Conditioner/Heater - The appearance of condensation is caused by the difference in temperature. What you can do is balance the temperature by toggling on the air-conditoner or heater's thermostat. Try to match the outside temperature, as much as possible. You will know you're on the right mark, once the droplets begin to fade. You might as well leave that temperature on, so the moisture will not return.
•Leave the Air-Conditioner's Vent Open - Leaving the vent open promotes a gradual change in temperature inside the car, which prevents the appearance of moisture. The difference in temperature between the car's interior and the outside environment also won't be big enough to begin condensation.
•Dehumidifying Solution - The solution will not prevent the appearance of condensation, but it will certainly speed up the removal of the water droplets from your windshield. Apply a generous amount on your windows and windshield. When traveling, a gust of wind is enough to remove the pesky coat of droplets. You can purchase the solution at all car supply stores.
•Park in an Enclosed Area - Enclosed areas, like garages and indoor parking spaces, have a more controlled shift in temperature, as compared to open areas. The gradual temperature change prevents the formation of condensation. So if you don't have an enclosed garage, better reserve slots at enclosed parking areas.
