I am a little lost on your explaination... but I do it the simple way. I never use the recirc button. I run the AC every time I use the car (it is hot down here). Sometimes I turn the AC off while driving and leave the vent on so the outside air blows through and drys everyting up. As a matter of fact, in the 4 years of owning the car I never turn the vent off completely.

Or while the car is turned off I hit the ricirc button and let it blow the cool air out and dry everything up... a really nice feature our crossfires have (I didn't even know about it until someone on this forum told me). It also helps keep the car cool or warm if you are running into a store.

Never had any wierd smells.
