[Dadillac]

So I got home yesterday at 3pm. Parked the car in the garage. Around 930 pm I went into the garage which is quite silent. All of a sudden I start hearing what seems like an electric motor running. At first I thought it might be someone outside but the noise persisted. Searching around it was apparent that it was my car that was the source of the noise. I got on the floor and know that the noise was coming from the rear of the car. What could possibly be running on a cooled down not running for 6 1/2 hours car? It kind of reminded me of the self leveling motor for the rear suspension on a previous Cadillac I formerly owned. Anyone?
