Okay I know there is a rain X and that's for rain. Is there anything like that for fog? My other family cars, (including the 11 year old Camry) doesn't even fog up during cold nights, but that damn Accord gets fogged real quick. I got rear tinted windows too so any suggestions? Thanks (ps...I know it's not for a Toyota, but still this could happen to any car)

 

I have some Rain-X anti-fog that works really well (especially in the bathroom), but I don't know if they make it any more.

For quick defogginf in the front, turn on defrost, and hit the A/C button, and it clears it fast, eventually it'll help clear the rear window also.

 

Thats the way i take care of the fog.
As for the rear window, If you have a quality tint job you can run the rear defroster and not have it bubble up like you see other cars. If it bubbles its a cheap tint. Im goin 5 years on my wifes civic and she uses the defroster, no bubbles.

 

Could it have excess moisture inside? A leaky firewall grommet from a bad alarm/stereo install, or leaky rubber moulding? Just a thought...

 

Well I had an alarm installed two weeks after I got the car in my home. As far as rubber molding, I found that the rear window one needs a new, it almost looks like some trying to take a heat source of some sort and put it to two sides of the rubber (it shrank is what it looks like and somewhat eaten away). I plan however to put in the new rubber when the car gets repaint sometime next year (probably close to when the Tundra is paid off)
