I have a 97 Accord and I've noticed when i drive that my windows fog up. The problem is, i am not losing any coolant, the reserve tank is always full. I can roll a window down, and the fog goes away. When i park the car, there is no moisture inside the windshield, the carpet is dry, and there is no visible coolant under the car when I park it. Also, I don't see anabnormal or rapidloss in pressure on the hoses when the car is shut off when I get home in the evening.
Has anyone had this problem or a suggestion? Thanks in advance.

 

welcome to the forum, is your a/c system working, the a/c system gives off dry air to clear the fogging up windows, if the a/c system is inop, you have humid air in the car and will not clear up until the window is down.

 

Thanks for your reply, but I found the solution. I had the recurculating switch in recirc, instead of fresh air. I found the owners manual for the car and it says to run it in fresh air mode or the windows will fog up. I have never had this occur in my past vehicles. But I now know. Even my '09 Corolla does the same thing.

 

thank you kindly for the fix, now we can all gain knowledge on a fogging window fix.
