My car glasses, window glasses(inside) are all victims of the frustrating effects of fogging. I use to start up the car, turn on the defogger, and… wait and slowly they go away. But sometime, thousands of tiny water droplets form on the glass from inside and even turning on the debugger for long time is not helpful, making oncoming traffic hard to see.

Any suggestion of how to get rid of this problem is welcomed.

Thanks in advance

 

If you're not turning on the A/C (or it isn't working), you're not getting the full benefit of the system.
The A/C acts just as a dehumidifier, condensing moisture out of the air via the cold surface of the Evaporator Core. It's this action, in conjunction with heat (warming the glass) and using the Recirculation function; that gets the windows clear.
You may have other issues working here as well tho. Having water bead up on the glass is an indication of very high humidity levels. Either you're prone to getting into the car with your clothes soaked in water, you've a water leak somewhere or your Heater Core is leaking.

something to ponder

You have to use the a/c. If your airconditioner works, it will defogg the glass in a giffy. A/C on with heat turned up will work quickly.

 

I used the combination A/C with Heat and , but does not help. Is there something wrong with A/C ??? But, heating and cooling works well, car heats up quickly during winter.

I never used Soak Cloths, or any kind of soft stuffs to clean my glass.

 

cars A/C won't work when the temp drops below 30 or so........do you get hot heat? does the car smell sweet when you use the heat? you might have a leak in your heater core. it has been in the teens and single digits here and I get enough heat in about 2 mins to start defrosting the windows.

 

I never sensed any smell, sweet smell coming out when I turned on A/C.

True, when I turn on defroster it takes time to heat even longer to 2 min (not sure how much mins).

 

You might want to check you A/C system. Unlike some who purport the A/C doesn't work below 30d, both the A/C in my '97SE, and my wife's '97LX work just fine for DEFOGGING the interior (true however, It will have no bearing on DEFROSTING. only heat will do that). In fact, it works so effectively that for a two hour drive, my shoes will dry; as does my jacket and anywhere inside the car that got wet from snow or rain.
Although it sounds completely counter intuitive, the A/C works just as well with the Temperature dial calling for heat, as it does when calling for cold.
You've only several avenues to address this condensation issue (Yup, same condensation as that on the Ice Cold Coke can (with Lime))
1) Open a window and exchange the cold dry air outside for the moisture laden air inside. (freeze your butt off)
2) Heat the windshield to the point that the moisture laden air inside won't condense on the glass inside. (and overheat yourself)
3) Dry the air on the inside so that there's nothing to condense, and apply moderate heat. (and stay warm).

Thank you all of you for your input. I will get my A/C system inspected from Honda.
Another winter tax from pocket.

 

P_,

Manual for the 1994 accord states that it will not work below 35F and although I can turn the A/C the compressor will not engage when it is really cold outside. My A/C is functional and when the temp is 25 or warmer outside my A/C will come on. Also the A/C will not come on if the evap temp is below 32 to prevent icing......

 

This is one of those topics which are better left for days when you've got a few good friends sitting around a fire kick-in down a few Sam Adams.

I'll have to consult the Honda Guru (Not DH, he lost that designator when he wimped out and changed his avatar LOL ).

My understanding is that they specifically designed against that contingency by routing cabin air intake thus:
Fresh Air Intake / Recirc Intake
Heater Case / Core
Evaporator Case / Core
Distribution manifolds (Ducts)
Outlet Registers

The heat from the heater core keeps the evaporator from icing (as does the thermal bulb sensor on the Expansion Value Assembly). Even IF the Evaporator Iced up, the system would shut off the compressor until it thawed; it would than allow the system to restart.

Additional note: In the 1997 Accord Owner's Manual, the only reference Honda makes on this topic:
"This setting is suitable for all driving conditions whenever the outside temperature is above 32d F" Page 79, center column.
There is no mention of the A/C not working.

do you have a trunk leak that might be adding humidity to the car interior?
