today somthing strange occured. I was driving back from the airport and I turned on the a/c. just as I did i hit the button directly to the left of it ( i don't know what it's called). All of the sudden there was like a fog that came out of the vents. I immediatly shut it off just ran the fan and it stopped. I had the a/c running about 15 mins earlier before that happened and had no problem. I the turned it on again for a min and it was just fine.

Has anyone ever experianced this before.

 

YES--It is condensation in the evaporator case. The button you mention is the recirculating air control which blocks off the air intakes to the outside of the car.
Not to worry
