I've had problems with the fogging for quite some time now. Just in the center and sometimes enough to where it actually drips down the inside of the windshield.
I would say I experience it more on a sunny day than a rainy one - garage parking surely helps - but if you had the problem you would probably know it from that whining noise that comes from "in there" as soon as you open the door of the car.Odd.... never had the problem. Parked in Garage most to the time, but even when outside in the rain, have not experienced.
The problem with the HVAC units is the blend screen they use either breaks or squeaks when going through the wake up process . After the screen breaks the unit defaults to the defroster and cold air continues to flow out of the vents . Changing the position where you want the air to come out doesn't helpAre you relating the fog to the noise. Reason for asking is that the last thing to happen when the car goes to sleep is the dampers in the HVAC go to a rest position, and most cars typically open the recirc damper to outside air when you open the car door to vent the cabin and make the door easier to close. then shuts it after you get out. when you open the door, it quickly wakes up the system and returns the dampers to proper positioning. most likely what you are hearing. I haven't had any customers up here with that complaint, so may be a heat related issue. That sounds like a case of mosture residing in the HVAC unit that is evaporating out of the defrost vent when car sits in hot sun.? My 2 cents.
Harleyguy has seen my problem first-hand, so i adopt his response to your question (the fog is related to the noise). I thought nearly everyone had some issue with the HVAC, so the poll results so far are comforting. Lets see if that holds when the sample is large enough to be representative.Are you relating the fog to the noise.

I just have to turn the air on and off a couple of times to get it cooling again. But I do have a crazy loud noise from the engine cooling fan at low speeds whenever the A/C randomly decides it wants the interior fans to go above 5 (usually 9). Then I manually bring them back to around 3restart the car after a soft reboot to get the air conditioning to provide any "cool"
