A/C misting window

[subwiz]

I started to notice a slight misting mainly on the drivers side on the window if the air is running in auto mode at 72 degrees or lower. It seems to be blowing about 50% of the air via the window vent and 50% via the face level dash vents.

Then again it might just be the current weather conditions in Central Florida?

Does anyone else notice this same issue?

Thanks,

David.

On your A/C display, is the UP arrow (defroster) on or off? I'm in central FL too and run my temp at LO all the time without the upper or lower arrows. I find that if I am running my defroster it will fog the lower part of the windshield and the door windows too.

Hi Fasterjames,

I don't have the up arrow displayed, just the word 'Auto' ... could you run your car with just the 'Auto' word displayed and see if you have roughly a 50/50 split on air flow to the window and dash vents?

Thanks,

David.

if you're running in recirculation mode you'll tend to have more condensation.

Nope, not in recirc mode either ...

When mine mists in AUTO mode I just hit the middle and lower fan buttons so the air is not directed to the windshield.

When cold air meets hot glass condensation forms.

Hi David,

I tried this for the past two days. Wednesday no condensation but yesterday afternoon the bottom of my windshield fogged up. Windows in doors did not. Here was how it happened. 97 degrees yesterday, car sat outside at the convention center in the sun. When I left I hit AUTO and moved the temp to as low as it would go. Recirc was off as well. Eventually it started throwing air through the defroster after the cabin was getting cooler and this caused the condensation. I think it had more air going to the dash vents and after they started to slow down the defroster vent increased.

My guess is that somehow it senses more heat from the dash area and therefore automatically turns on the defroster. How and why I wouldn't have a clue.

When I took it off auto the condensation went away after about 5 minutes.

I hope this helps.

I am assuming the condensation is on the outside of the window, not the inside (if it is the inside then please let us know). Try making sure the vent is not aiming directly at the window because what will happen is the vent will make the window so cold that outside humidity will attach/condense outside of the window. Same principle as a cold coke can on a hot humid day outside - it will start to get condensation on the outside.

Actually no, the condensation was on the inside of the windshield which really perplexed and frustrated me because it wouldn't clear right away. (windshield very clean) Any ideas? Thanks.
