I was driving today and white mist shot out from the vents... I thought it was smoke at first but once it cleared there was moisture on the vents... I tried to smell it to see what it can be and it was odorloess. i don't think it was water. What is this? I popped the Hood and didn't notice anything.... Can someone tell me why this happened? By the way the ac was on and it was on refresh mode..... Not Recirc... Should I take it to the dealer and have it checked out???????
