When I use the air conditioner on my car, and then shut the air off, I'm getting a "funky" odor from the vents (on fan alone) that smells like I have been smoking in the car. As an ex-smoker, I know the smell, but this car was brand new and shouldn't have ever been smoked in! Has anyone else noticed a similar problem with their smart? Also, does anyone have any experience with how to "neutralize" or "sanitize" the air conditioning system on a car to correct a problem like this? I have a vanilla deodorizer clipped into a vent, and it makes the car smell nice, but once the air conditioner is turned on, and then turned off later with just the fan running.........there's that SMELL!!
