foggy windows help needed

I have a 94 saturn and when its cold out side or raining all the windows
gets so foggy inside I have to roll the windows down or be constantly
wiping all the windows and the defroster works only on the windshield
rear glass has a defroster install in the glass it's ok I just found
the n/g and dont know if the problem has been posted before thanks

 

Do you run the AC and set the temp to HOT? ...I used to have good luck with
the AC.

 

Make sure recirc=OFF. This is in your owners manual.

 

Under some conditions, a leaking heater core could be
putting a lot of moisture into the air inside the car.

 

Make sure that the inside of the glass is clean. Any dust or other schmutz
on the glass gives moisture a better place to condense and create fogging.
Use a good glass cleaner and a squeegee.

On my '01 lw300 at least, the defogger position will automatically turn on
the A/C (regardless of the setting of the a/c button). Problem is at low
temperatures, the a/c will not dehumidify. So, in very humid weather near
freezing, the only recourse is to leave the window open a crack and crank
the heat in defrost mode.

Make sure that the recirculate control is off. It may be more energy
efficient to recirculate the air but if the a/c can't dehumidify it, the
problem only gets worse.
