Window foging?
I have a 1980 and it fogs up really bad. I don't have AC but I do have a sun roof. Cracking open the sun roof helps but does anyone have any good ideas on how to prevent our windows from foging up?
Does installing new window and door weather stripping help?
Does window tinting make any difference?
Does anyone with new window glass notice a difference compared to the factory original?
I'm interested in this because modern cars, or at least my '00 SUV, does't have this problem at all. Even when I make sure the AC is not on. Is ventilation better on newer cars?

Don't use your recirculate button when you run the heat, moiusture collects and circulates through the car sticking to the windows, pull air from the outside since it's nice and dry. It wont blow as fast but there's nothing you can do about that.

There's a window cleaner that prevents fogging... can't remember the name of it.
Mine don't fog... maybe I'm just special? Or maybe my weather stripping is so shot that enough air flows?

water under the carpeting increases humidity inside the cabin and makes it fog. very common in 1st gens. there is a plate under the carpet in the general area where you put your feet. plate is an access panel and it covers the top of the frame rail. they come off and water from under the car gets in there.
besides the normal check all your body gaskets including grommets on the firewall.
Rain-X sells an anti-fog you wipe on the inside of the windshield it works very well but only lasts about 5 days per application and attracts dust.
after it rained, the windows of my REPU would fog real good. lifted up the carpet and there were puddles on the floor!!!!!

I have an 85 GS which has/had the same problem. What I think the window fog comes from is moisture on the inside of the car. This is what I did to eliminate the areas of moisture in my car::: I used RAIN-X on the inside of the windows that did not have tint on them. I didn't do anything to the rear windows because they are tinted.
Next::: I removed the rubber drain plugs located in the floor of the car. The plugs I removed are in the lower portion of the spare tire storage area, also the plugs underneath the storage bins behind the front seats as well as the plugs in the floor infront of the seats. I put a couple of newspapers over each of the open holes underneath the carpet to block/soak any water that may splash into the holes.
Next:::I drilled a small hole on the INSIDE of each rear lower quarter panel. From underneath the car. This will help to drain any water that may leak into the quarter panel thru the wheelwell. spray RUSTOLIUM on the holes to prevent future rust.
Like G Juice said DONT use your recirculate button. Not for a while anyways. Once your car clears up...put back the plugs in.

Here's a thought: your heater box or the heater control valve may be leaking. first clue would be wet carpet, especially around the heater assy. Even if these were just "weeping", they could be giving off enough moisture to fog up. You could disconnect the water flow into the passenger compartment by directly connecting the two pipes that feed it on the passenger side firewall and see if the problem goes away. Might get a bit chilly, though

It is a long shot and even though you probably have not run the AC in the winter recently I would check the AC drain as it could have pulled out of the hole and started leaking in the floorboard. It happened to me and rusted all around the ECU. I was going to replace the insulation and carpet anyway and found it before it got worse and could fry my ECU. If it leaked in the Summer or Fall it could leave the water in the absorbent insulation to come out later. I run the AC occassionally just to keep the hoses lubed. Sometimes in the winter I run the AC to defrost as it takes time to get heat.

rain-x works well on the outside of windows, but theres not much i've found i can do about the fogging of the inside of the windows. the worst part is, my driver's side regulator is shot, so i cant roll it down anyway! haha.

FOG! i would love to compare. i bought a squegee just for my inside. swipe it a couple times and i'm good to go. then i keep swipin in intervals. my carpet is soaked though so i'm guessin the floor or the door seals are leakin bad. well, i know the door seals are with out a doubt.but with the rain i'm too lazy to pull the carpets, maybe in the spring, or summer. but then i will forget about it until winter comes again and it will be rainin. CRAP! reallity sucks.

Many, if not most new cars DO use the AC when in DEFROST. Air is 1st "dried" by the AC, then heated. The "dry" air will then not condense on the cold windows.
