Vapor coming out of air vent
 

I've been driving without my fan resistor for about two weeks. When I have the fan blowing on high everything works ok. However, several times when I was using the air conditioning without the highspeed fan onvapor came out of the airvents. As soon as I turned the high speed fan on the vaporwould go away. The air never stopped working, it seems to be cooling ok.

Do I have a problem developing? In the past vapor always meant the coil was leaking. Or is it related to only having the high speed fan?

Thank you,

Booker

I had a 2000 Caravan that did the same thing for years. Is your air set to inside or outside source? Depending on humidity levels outside it could be as simple a high humid air being cooled, and you seeing it like a cloud. Change your air to inside source and see what happens. I bet it will stop.
