so i was driving around today for about 45 minutes and had the ac on full blast with the windows up and out of nowhere white smoke starts coming out of the ac vents. It didnt really have too much of an odor, but it was definitely there. Then i pulled over and turned the car off, popped the hood and looked for the cause. Nothing. This is about the third time this has happened in 2 weeks. I dont know if i have oil or coolant leaking and burning or what. the only thing that i have done to the car is relocate the coolant overflow tank and install the wizaired intake. what do you guys think it could be?
