Today while driving in a pretty wet day in Brisbane, I put the air-conditioning on, it had been off and on during my trip,. All of a sudden I seen white smoke I thought coming from vent, I thought the workmate was on fire, then I turned off air con and all was fine. I tried it again, same thing, anyhow, when I got home I switched it on again and it was fine, no smoke/fog,. Anyone had this happen before, cheers john
