It's cold up here in the Midwest, with temps getting close to 0F at night and the low teens during the day. I'm noticing that my driver's side interior window and the driver's side (only) windshield tend to fog up. I'm assuming it is doing that due to the driver's (me!) exhaled breath condensing on the very cold interior window surfaces closest to the driver. The problem is that I've never had a problem like this in any other car before. None of my Prius have this problem. My Volt didn't. Usually having the heater on sends warm air to the side windows, so those wouldn't fog. The windshield.......not sure why that's fogging. Yes, I realize that I can turn the windshield defogger on, but even then it takes quite a while to un-fog. Again, in my other cars just having the heater on seems to prevent all the windows from fogging up. I'm wondering if I have an airflow problem to the driver's side of my car? Hard to quantify, I guess, but even the little vent by the side window doesn't put out much air with everything in auto. Anyone else noticing this problem?
