Sorry to hear about the misfortune

The rest feature should only run for 30 minutes (I believe).
Key out of ignition, blower stil running longer than 30 minutes... sounds like a shorted control module.
First trip to your dealer. From some of the posts on this board, I have gathered that not all dealers treat their customers as well as we do. I would recommend that your vehicle be taken to a five star dealer that has a Crossfire certified technician. Although dealers can be somewhat impersonal; the Crossfire is a specialty vehicle- Most of us who are certified to work on them volunteered for it because we love the car. See if you can meet the tech- I like meeting and chatting with my Crossfire owners. It makes working on the vehicle personal and the care I take on your car is the same as if it were my own. Best of luck- let us know how it goes!
