This would be your Sensor fan for interior temperature, it is a small electric fan installed in the a/c control head, draws cabin air past the climate control temp. sensor. If you are lifting the handle or unlocking the car after the car has set for 16 minutes...you wake the car up and the little fan comes on. This is normal, trust me, if you sit in your car after you remove the key from the ignition, just lock your doors & sit there for a few......the fan will shut off on its own....
