So last night it rained pretty hard here in R.I. I got in my truck this morning on my way to work, kicked on the a/c and headed off. As I pulled onto the highway, I got on the gas pretty hard and noticed that some kind of smoke/ water vapor was comming throught the a/c vents. I was trying to smell to see if I could tell what it was. There were no indications that anything was wrong, truck accelerated fine, no black smoke comming out the back. I think it was just water vapor, but has anyone else ever experienced this?? How would that happen??
