I seem to have what appears to be steam coming from my air vents. It has only done it a couple of times, and only when the air conditioner is on. It seems to work ok, but is something wrong with it?

 

Normal if you have A/C on full cold and blower on low and it's been on a while. Evaporator will tend to frost up and blow frost out the vents at times.

I've had it happen a few times when it's been humid outside. After our last rainstorm (which we get few in AZ ) I started having fog come out of my AC vents. I freaked out and pulled over thinking something under the hood was smoking. I called my fiance and he said it happened a few times to him, no big deal.
