white vapors from ac vents

I recently noticed some white vapors coming from the AC vents of my 99 RAV4. I would turn the unit off until I can bear the heat no longer. When I turned the AC back on, everything is fine. This has happened several times in the past 2 weeks. What was the source of the white vapors and should I be concerned? The AC system has never been worked on. Thanks

Probably water vapor. You are making your own miniture clouds.
Check under your RAV after driving for a while with the air on and see if water is dripping underneath. If not, your drain tube is clogged and condensate is accumulating in the heat/air box. If you unclog the tube the cloulds should go away.
