Any anti-freeze odor?

Monitor your coolant level - this must NEVER drop...

How is your heat intensity ?
And does the AC function - this makes a good dehumidifier along with the heat.
Nearly forgot; has the cabin filter ever been changed and the composted gathered up ?
And, lastly, have the drains ever been cleaned ?
This is all normal service work..

Any leaks anywhere (especially the trunk which is most common)? Any type of moisture in your car will evaporate and condense on the windows causing fog. I leave my doors/trunk open overnight periodically and applied Fog-X to the inside of all the glass, and it seems to have eliminated the fog.

You can use the AC for warm air too, and the AC will remove any moisture from the air before moving it into the cabin. In some (most?) cars when you turn on the defroster the AC will automatically be turned on because warm dry air will defog the windows better than warm moist air (which would potentially fog them more).

Turn off cabin air circulation button. Allow outside air to be mixed with cabin air.

A friend of mine used to drive his car in recirculate mode all the time and wondered why it always fogged up. :roll: When mine fogs up, I usually put the sunroof in the vent position (back end tilted up). That seems to let the moist air out and doesn't let rain or too much cold air in. Sometimes I'll use the A/C.

Good catch, SigP
I forgot about that one.
I think Saab and all the others should hide that control...

I just can't get over how good this forum is....:cheesy:
The quality of Saab owners...

Yeah to properly use the defog function:
  1. Open the recirc vent, let outside air in, don't recirc inside air.
  2. Turn on A/C. this will dehumidify and dry the air.
  3. turn the heat up
If you're still having problems you have to ensure that your a/c system is working properly, if it isn't then the windows will fog up more rapidly.
