defrosting/defogging rear windows?

[stealthshooter]

For you guys that live in cold places what are you doing to defrost/defog your rear Windows? I have the stock heater and it keeps up on the windshield but is not up to keeping the rest clear. Have any of you put in a second heater core and fan for the rear? Also how about putting a wiper on the rear window?

I've seen stick on elements somewhere, that might work better than air? Rain-x might work too? Never tried rain-x but I've heard some talk about it.

I'm a bad example though as right now I have no heater installed and my driver's side fresh air flap is broken.

Just yesterday went up to the ski hill and back - had no problems with fogging but I had a little trouble steering with numb fingers! In all seriousness, an old trick of mine when it is snowing is to keep the inside as cold as outside and snow doesn't melt on windshield - fresh cold air on windshield keeps wipers from loading up and fog from forming.

Keeping fresh cold air blowing will keep the moisture down and windows defogged. Probably you'll like the first couple of solutions better than the cold air trick,..

The elements sound interesting!y wife and kids hate it when I roll down my window to clear the fog up! So yes the elements would be better!

Have you thought about one of those trans coolers with a fan built on it?I have thought about building a rear heater out of one of those tapped in to my heater lines before i cut my cab.It could be mounted anywhere.

Makes it worse. Rain-X makes glass hydrophobic. So the water forms little balls, fogging over the glass. If you can't prevent the water from forming you at least want the water to flow into a uniform layer. Old trick from diving is to coat the inside of the lens with baby shampoo. It breaks down the surface tension of the water and allows it to flow and not fog over.

At one time there was an aftermarket rear window heater grid kit. They were horrible when they first came out. Don't know if they ever made them any better or if they are still around.


Now Rain-X does work great on the outside of the glass. Where wind can roll the beads of water off the glass. Been using that for 25 years and it is still great stuff. Not as effective on a Bronco, glass doesn't get good airflow that an aerodynamic vehicle gets.

We always have to ask first if you have the center fresh air/fan knob pulled all the way out?

Rain X make antifog stuff you put on inside of your windows works great! use it on all my old cars and my Bronco! It works for me!

.

Would that work on glasses or goggles in winter ya think? I have a real problem with glasses fogging in winter. I've used the spit on mask before and worked fine for recreational diving but I have a real issues with outdoor sports in the winter.

I've tried cat crap and no fog, was thinking about looking into this nano hydrophobic stuff but if I understand what you're saying rain-x or any of like ilk won't work on interior surfaces?

Ditto. The original rain-x is great for outside of the windows. It even helps scraping the ice off easier!
Rain-x does make an anti fog for interior, but it leaves a haze that is a pia to work out, and doesnt work all that great. Im gonna try the baby shampoo

Do a "google search" of Mojave Heater - they're an auxillary heater that is supplied by your existing heater hoses and has a fan . If you can't mount the heater where it will blow onto the rear window you can mount a small fan on the back of the rear seat or rollbar or - and point it toward the window.
Of course this only helps on the inside .
Do a "goggle search" of electric window defroster . There are multiple aftermarket kits you can install.
Rear wipers are probably doable also - it could be set up just about like the front windshield wipers.
Pretty much anything is possible on a Bronco ; it's just how much time , money, effort you want to go to.- oh and your capabilities - and creativity

A 12 volt fan like this works pretty good.

HMM My rain x anti fog never leaves a haze, and works perfect on my bronco. I must be lucky to not have problems I cant solve simply on my old cars I drive everyday. lol

found this web sight looks like a stick on film in custom sizes

 

[moosebob]

I just ordered up one of those kits from Mikes previous post.

For $75.00 its worth a try. I will post install pics and a review.

Please keep us posted on how that kit works looks pretty slick and should work well. Just one word of caution if your window is tinted with film make sure you cut the film where the strips will go or if you have it tinted do the same and leave a small gap between the two or the film will bubble. I have been working on a small heater system that will go in the quarter panel near the tail light and fuel filler neck as I have quarter panels to cover it. It will only recirculate the air which will work better for defrosting anyway.

someone told me about this years ago and ive used it many times...nothing more aggravating than driving over a bridge and windshield fogs over lol

simple and cheap as heck...take the can of Barbasol smear it on glass. i use a paper towel to smear it. then wipe it off with more paper towels...it takes a bit to get it completely dry again and clear....but it works!!!!! do try other shaving creams...use Barbasol!!!

Not sure how much fab you want to do but when I was grabbing seat belts from a new Dodge minivan with rear air and heat. The rear heat module was a stand alone set up with only water and a/c lines coming plus the electrical. The duct work looks easy to re-use also. The whole unit was shaped around the wheel well too so it fit nice and tight against the cab wall.
