Outside temperature about 17 Celsius, windows up, travelled about 15 minutes at 90 km/h.....no heat or A/C on....
Parked car for about 5 minutes or so...come back, hop in and see moisture on windshield (inside) above where the defrost is....roughly the diameter of a basketball......disappears after a few minutes of driving....

It resembles when you have a leak in your heater block and that does the same thing on your windshield....however, there is NO smell of coolant in the vehicle.......

Ideas???.....

Thanks

residual moisture left over from the previous cooling session.
With vehicle parked- the moisture left over INside the ducts evaporates and then condenses on your cool glass...

You may sometimes see this when you also turn on your fan- and briefly--- the window gets a little foggy as air moves thru the vents...

Wow.....first vehicle I have ever owned that has done this on a "normal" basis....

So in other words, there is no problem....but that is really wierd...

Thanks

Ive seen it in several vehicles....
most recently- our 07 Impala... 2 days ago.
I told my gf------- Youve been running the AC havent you?
she looks at me with a "how do you know" expression.

I rarely use the AC in my Trailblazer--- but I recall seeing it once or twice.
Once I drive the Traverse more--- well see...

But It may be possible to control this-
and this helps with the AC musty smell---
if you use the AC--- maybe 3-5 minutes before you get to you destination- and if you or your passengers dont mind--- turn the FAN on HIGH- and if you want (and its not too hot).. roll down the windows a bit...
get some outside air (turn off recirculate) flowing thru the ducts--
hopefully this dries off leftover moisture and to control the musty smell and the fogging windows.
