I have the same type of issue with my crossfire, I have a 2005 limited coupe, six speed manual. Once I start the car up and it has been running for a while and I decide to turn off the air conditioner, it will continue to blow even if I turn it off. I have tried several different combinations, like making sure the recirculating air button is off/then on, but sometimes I turn the air to the off position, and it continues to blow. Since I live in Texas it is very hot here and the air conditioning is actually very cold so I haven't really bothered with it any further.
