Condensation on the outside of windscreen...

[aTOMic]

Where I live, the humidity is always, oh, about UNBEARABLE percent. I have two 2004 D3 A8ls. The higher-mileage car does it more often. I think the seal(s) on the temp / mix control doors on the HVAC get leaky with age. Only cure is towel laid across dash, but I never think of that until it's too late. It IS maddening, especially as it is a nightly occurrence here.

When I lived in New York State, circa 1970s, one night I saw a 1960's VW Bug with five or six votive candles across the bottom of the windshield. I thought Wow, the guy must be a PRIEST! Later I told my Dad and he laughed and said "Oh, that's so-and-so; he's an engineer (at GE where Dad worked) and he's too lazy to fix his defroster!"
Lazy or SMART I wonder! Boy I have not thought of that in a long time!

I'm not sure if there's coding to set the HVAC for "Sweaty" regions, which would close the vents to the windshield, or if Audi thinks that some air movement is necessary there. Just last night I turned the distribution to manual and selected the dash & floor vents. Tonight I'll try to remember to crank the fans up to 11 and see if I can detect a difference (Hope not, as any setting besides "AUTO" is SO gauche!
