I need some help. I was searching this board last night for my answer. Anyway, its usually about 40-50 degrees outside at any given day. And everytime I get in my car the windows fog up, and they fog up really fast. its been driving me crazy because I can hardly see. So I searched here and someone said Eagle One 20/20 Glass cleaner. So I gave it a shot and bought it. Sprayed it on wiped it in really good and made sure I didnt leave any residue.

Windows looked great up front during a drive, no fog on the main, driver side, passenger side front windows. The back ones still fogged. So I thought ok this is fine. Get to school and get out and leave my car for 1.5 hours. Come back and ALL my windows are fogged up incredibly bad. It took about 10 minutes of solid heat to start breaking up the fog.

I'm out of options to get rid of this fog. Its never been this bad in any car I have driven. what should I do?

i heard somewhere that it's not always due to the windows but the cabin filter. try replacing that and then see if they still fog up. :dunno

it's worth a shot. from what i hear it's not expensive to do this either.

Are you using the AC with the heat?

Ive tried heat and ive tried vent, my AC is really low so it doesn't really blow cold air.

The A/C is useful to de-humidify the air, if it's low that may be your problem.

Thats weird, any other car I have ever driven I have never used A/C (some cars didnt even have A/C) and it has never fogged up this bad.

Get RainX anti-fog for the interior glass. While you're at it get RainX for the outside glass, because it works damn well in the rain.

The A/C is useful to de-humidify the air, if it's low that may be your problem.^^^ Use the AC and the defrost setting, with the temp on hot.
