Fogging / misting of windscreen during rain

[rusty260z]

my heater dose move all the way to the right hand side so that i can direct the air to the windscreen. it get jams up about an inch from the end.

- does the hater blow air on the windscreen.

- why is it not travelling to the end.

the heater dose work

car is a 1977 GS31 fairlady 2+2

are there any alternatives, i need it to work cause i use it everyday and it gets a bit hard when it starts to rain and its starts fogging up, i usually have the window down but if it rains from the wrong direction then i cant have it down.

As a temporary fix, get some never fog(made by the same people who make rain-x) also, put a few bags of dessicant in the car-it will lower the moisture content all day, and lessen the propensity to fog as well.

Your control cable is out of whack, correct it, and your heater should work, but, the seals in your heater box have probably crumbled to the point of falling apart. Then address the heater problems.

DO NOT USE NEVER FOG!!!

I am not kidding on this. It will permanently fog and haze your windows. Then when you drive into the sun, presto zesto instant white haze that's almost impossible to see through.

Voice of experience here, I did it on my Acura and had to live with the nonsense until I had the windshield replaced.

Your flapper valve inside the heater plenum may have lost it's "seal/padding" that goes on the face of the flapper. If that is the case, it will not allow the valve to close properly and hence most of your air will be vented to the floor.

ENRIQUE IS RIGHT!

I'm still wiping the windows down every couple of weeks trying to get the crap off.

i tired that rain x stuff, and had similar experience, had to use pretty strong window cleaner to get rid of it.

You guys must have something different in the air, or maybe the formula has changed. I had a beater occasional use PU, and used never fog for years on it-no climate control. It was always parked in the hot Georgia sun- I never had any similar problem.

Btw. Alcohol or vinegar will remove almost any glass coating(warm the vinegar and apply a paper towel the glass (a wet paper towel will stick to glass until it dries) to disolve perminent water spots.

The hotter the water the better for any glass cleaning. Yep, vinegar or rubbing alcohol will most likely do the trick. The trouble with these products and most over-the-counter stuff is that they contain silicon oils. This will eventually damage your rubber seals and make them turn white. Stay away from silicon oils.

The gaskets on the flap vents or the cable adjustment is probably what needs attention. Those gaskets were just cheap, low density foam. Made for disintigration.

I had problems with Never Fog when it first came out. Tossed the bottle in the garbage within a week.

I found it on a Corvette forum about a year ago. I collect and save lots of small (and hopefully funny) images for use as avatars.

According to my handy little yank book, Fast Fixes and Simple Solutions, squirt a few drops of shampoo onto a rag, wipe the windscreen and the fog will clear up.
