Car Forum / Honda Cars / July 2005Re: 1990 Accord windshield fogs up
Hi all, My 1990 Accord windshield fogs up very badly when it rains. I put the controls on 100% defrost and crank the fan up to highest and it still fogs.By the manual you are supposed to put the A/C on to fix this. When it's 10 C out ((50F) this seems rather odd and it's awfully cold as well. Other vehicles I have driven do not seem to have this problem to anything close to this degree! Is this normal? or is there a problem either with my vehicle or with what I'm doing? Thanx, Canadaloon > Hi all, > My 1990 Accord windshield fogs up very badly when it rains.

No more fog! ____________________________________ Do not write below this line. Reserved for me. Or for something a little less disgusting try rainx anti-fog. > Best and cheapest way to solve this is to spit on it. No more fog! >Best and cheapest way to solve this is to spit on it.

Spit on the Retard while you are at it as well A lot of other cars will kick the a/c on with the defrost (without you even knowing it)... make sure you set the temp at HOT, and you will still get hot air. > Hi all, > My 1990 Accord windshield fogs up very badly when it rains.

I will second the Recirculate button comment. >> Hi all, >> My 1990 Accord windshield fogs up very badly when it rains.

In SoCal, perhaps. Where I am, recirc air gets wet.

Usually there is a warning in the owner's manual to make sure it is not in recirc if you are trying to clear the windows. > On 9/1/04 10:13 PM, in article > BdwZc.553$4et.135@news04.bloor.is.net.cable.rogers.com, "Steve Bigelow" [quoted text clipped - 10 lines] > Usually there is a warning in the owner's manual to make sure it is not in > recirc if you are trying to clear the windows. Recirc is only good if someone in front of you farts. I missed original message but I have similiar problem. Here's what I do: Turn heat on full blast [car will instantly fog] then turn on A/C to remove it. when gone, A/C to off then move temp control to cold with A/C off. Wont fog anymore. > Recirc is only good if someone in front of you farts. > > I missed original message but I have similiar problem.

What if the car does not have A/C? :-) > What if the car does not have A/C? :-) Then you're screwed in steamy climates. Can try the rain-x stuff, of course. > Hi all, > My 1990 Accord windshield fogs up very badly when it rains. I put the > controls on 100% defrost and crank the fan up to highest and it still > fogs. Sure. You're shoving very moist, humid air as fast as you can right at the windshield. It will fog up. > By the manual you are supposed to put the A/C on to fix this. That's correct. You want to solve the problem of moist, humid air going to the windshield. You need to remove the moisture from the air. That is the sole purpose of the A/C system. So turn the A/C on. > When it's 10 C out ((50F) this seems rather odd and it's awfully cold > as well. The purpose of A/C is not to provide cold air; the purpose of A/C is to provide DRY air. It uses the physics of passing moist air across a cold surface to collect the moisture on that cold surface (think of a cold drink on a hot day, and how wet the outside of the glass gets) and drain it away, leaving dry air to leave the cold surface. Yes, that dry air is colder right there. But you have a car--and it has a great heater. So set the temperature lever to whatever's most comfortable for you at 10 degrees C, but leave the A/C on. Your car heater will warm the air back up and feed nice, dry, warm air right into your cabin. > Other vehicles I have driven do not seem to have this problem to > anything close to this degree! Other cars that you've driven turn on the A/C automatically when you hit the "defrost" button. Honda didn't do that until about 1998. They were one of the last holdouts on this, if not the last holdout. So you took your Honda and did with it what you did with the other cars: you hit "defrost" and gave it all the air you could. But what you didn't know was that Honda wasn't turning on the A/C for you with the defrost button. This is why you read your owner's manual of every car you own.
