Every once in a while when I turn the recirculator off and turn the temperature up over 72, I can hear the compressor get a little break and for about the first 3 or 4 minutes of the new temperature setting there's a really pleasant smell coming from the vents. I don't wanna say its cologne-like, but its not exactly cheap air freshner smell either. It's like a comfortable median. Are the cabin filters scented or something? (assuming they are, I'm guessing that the dealer-bought ones would be and not the store-bought aftermarkets)
