Well not in my VX but in my 99 Chrysler 300M. I only had the defrost on and all I saw was smoke coming out of those vents before I turned it off. I did notice that it only happened at 62 degrees or above. A very slight burn smell but not significant. The smoke was white and cloudy? The first time I noticed this is when I left the car idiling for about 5 mintues and as soon as I put in drive smoke came out only the vents. I opened my hood and there was no signs of smoke. Any suggestions? Thanks for the help in advance.
