Older honda are notorious for this problem. When you run the a/c, it removes moisture from the air being cycled through the system, so the windshield will clear. This is unfortunately normal for this car. You can use the a/c in heat mode with defrost on to clear the window also.

1997. Is it possible to run defrost without automatic switch on the air conditioning?


disconnect the wire to the ac compressor
However defrost works quicker if the ac is running as well as the heater as it removes the humidity from the cabin air ---main reason for fogging up--

Assuming that it is working in frigid conditions, sometimes The
Ac works with the defroster to remove moisture and the fog on the inside windshield. So, turn the defroster of unless you need it when the windshield fogs. You may be able to keep the window clear by opening the outside air vent and increasing the heater temperature.

Windows fog up


There is too much moisture inside the cabin. Either something is leaking water into the car, or your fresh air setting is not working on the hvac system. You can not run the system on recirculate and get rid of the moisture.

When I turn my heater and defroster on, a bad smell starts and the windows fog up but the air is hot.


This may be due to a bad heater core or dirty core with a plugged water drain, first see if the a/c works. turn it on and see if the air gets cold and if the ac compressor works.

The way the defrost works to keep windows from fogging up is that when the front defroster is tuned on the ac should also be on, on most cars when you go to defrost it will turn ac on automatic. the system then uses hot and cold air to remove the moisture in the air to avoid window fogging. if your a/c is not working then that may cause window to fog, but if you are also getting a smell then the drain that lets out condensation may be plugged and then water builds up and also mold from always being wet and when heat is on you smell that.


i want you to run the defrost and when windows fog up wipe window with hand and see if it is greasy . if it feels oily then you may have a bad heater core, the core leaks coolant out and steam and causing windows to fog up with a flim of grease.

What panel to use to remove excessive fog inside the car when it is raining


Defrost

If defrost doesn't remove the fog, or it gets worse with defrost on, you may have to have the heater core replaced.

AC/Defroster issue


On most vehicles the AC comes on when the defrost is on to keep AC compressor/clutch from seizing up from non use during winter months.

The windows fog up inside of my Volvo S70


Sure sounds like the heater core, the only other thing would be some time of leak that is raising the moisture in the car is the floor board on the passengers side wet? If not look toward the heater core.
