    I saw this on another forum, but people here may have more info.

    I have a F250 super crew, when I'm plowing the rear windows constantly fog up. Is there something I can do to keep this from happening? I looked for a suction cup heater without much success.

    I have the same problem, I used to open the rear sliding window a bit and that seemed to help, do you have one?
    Other problem is cold air starts blowing in there and man it gets mighty cold, my buddies GM has a rear defroster, pretty nice, I wish Ford would start offering that.
    I'll keep an eye on this thread to see if anyone has any ideas, I'd like to hear them as well.

    Sadly I have the sliding rear window, so some of these applications to instal an aftermarket unit dont work that well.

    i found that leaving the drivers window open but still keeping it high enough as not to go below a vent visor works really well

    When the Fog begins to build, I put the Dial to AC with the Temperature set to HOT! It stays good and warm, but the ACis removing the moisture. The only problem is the heat only comes out the dash, but I just switch back to regular heat when it clears up. Sounds crazy, but it works. Chris

    Keep the front defogger on high, and crack both windows open. This should solve the problem.

    As said above, run the A/C with the heat up.

    most vehicles when you turn it to defrost or even floor/defrost, or Mix the ac unit comes on and removes the fog. guess i will find out how well it works this year with the new truck.....last year i had a jeep wrangler with a rear defroster this year is a F150 extended cab....on top of that it has a topper so 3 windows to try and see through!!

    when you get in your truck get as much snow off your shoes as possible. it will melt and fog your windows up more. keep your defrost on high, if that doesnt help maybe victoryrider will help you pay for a new chevy with rear window defrost.

    I Used To Open The Sliding Rear Window And Peek Out Thru The Narrow Opening.

    Not The Best Method, But It Helped.

    Are your mirrors heated?
    Maybe You should try using your outside mirrors.
    I know that can be a real PITA. My 01 truck had a topper and I just couldnt see thru it to save my life.
    So all I did was used the mirrors, you get use to it.

    Side mirrors are what's important. The rearview mirror is overrated. After driving large trucks, you will never find yourself using a rearview mirror in a smaller vehicle. I rely on my side mirrors everyday.
