My TLS has about 1000 miles. I was driving with my ac on the highway. I saw like small puff of white smoke coming from the front vents. It never happen before...just today. And ideas????

 

It was probably just humdity (mist). This has happend on every car I've ever had with A/C. Seems to only happen on the most humid days and lasts only for a few moments.

Yeah, it's just the humidity and the differential between the outside and inside temps. Nothing to worry about.

For what it's worth, I concur with the above. I have seen the same thing on my Nissan 200SX and it was the humidity.

Yup, it's humidity. I used to live in Indonesia where the temp was typically in the 90's F and humidity is in the upper 90%. Every morning our car would produce visible mist out of the vents with the A/C on.
