I'm not sure if it's because we've had some rain lately. The first time I noticed a problem was just after it stopped raining (was driving through the rain) The windshield fogged up on the OUTSIDE just behind where the wiper blade arms in the center of the windshield. Two days later I started her up and she fogged again. I swiped it away then drove for about thirty minutes no problem. Then all of a sudden two fogs patches appeared again. Not so much worried but I'd like to know why and if there's something I can do to fix it. Oh and just for information purposes. I TOTALY LOVE MY CAR!
