When ac is on my front window fogs on the outside requiring me to use winshield wipers to clear. I have tried all the different switch blowing patterns. Any suggestion ? I had it in for 20,000 mile checkup and mentioned this but Porsce dealer did not check it. Initially he said it might be humidity controls.
