Just took delivery of 2011 XC-90 yesterday. Made a short trip today and returned the car to my garage but noted fan motor/blower continued to run even 60 minutues after engine shutdown. I kept hoping the fan would shut off but to no avail. After I re-inserted the ignition key and turned to position III the fan blower immediately shut down. I then decided to secure the auto-mode and turned the fan speed knob to fully off; also pressed the a/c button to off. I plan to monitor for the next few hours in hopes the fan does not start up again. If it does, I guess my next action will be to disconnect the battery before re-connecting to make a trip to the dealership. Suggestions are invited.
