So I walked by our new to us '09 while it was sitting in the garage and noticed that the blower motor was still on and air was moving out of the inside vents. The car had been turn off, with keys removed for over 20 minutes. Anyone familiar with this issue?

It is normal... it runs to dehumidify the air as I recall. So you don't get the musty smell in your car.

It does not run for the 20min. This is described in the manual, however basically if the ac has been on for longer than a predetermined time, once the car is turned off about 20-30 min later the blower will come on for a few min to dry the AC evaporator to prevent mildew from growing.
