I checked again this morning. Without even a key in ignition the sound is louder and has a clicking noise to it for a few seconds after I open the door but then goes back down to the low noise of a cd or a low speed electrical fan.

Is there any kind of fan running for HVAC to circulate the air even when the car is off?

Thanks,
