i was driving my car on the highway and had my ac on (max cold, on power setting 2) and all of a sudden i start seeing a smokey vapor coming out of the 2 middle vents. it got me scared for a second because i had been driving for about 3 hrs on the highway and i thought something was overheating, but no, temp was sitting right in the middle, everything was good. i turned the air off and still for about 20-30 minutes there was the same amount of smokey vapor coming out, it didnt smell at all. i thought maybe it was because i had my window down a bit, but its actually been bothering me as to HOW/WHY this happened, i know theres nothing wrong (i hope) but i just thought it was weird and i have no explanation for it lol.
