There is a compressor in the right rear of my LeSabre. Yes it automatically fills the air shocks until a switch shuts it off. The switch is set up to raise the rear of the car to level it. If the air shocks do not fill for what every reason, the compressor will not turn off. It does when the key is off on mine. Check for leaks perhaps with your some soapy water. If the lines are not leaking and the compressor is working the compressor should shut off when the shocks raise the rear the correct height. If not I would look at the control switch however if it was the problem, I would think the back end would be higher than normal. My compressor commonly runs for a minute or two after the car has sat for some time, especially In winter months. I ignore it. It is designed to turn on when the rear is not level but should shut off with in a couple of minutes. If it is a perfect seal it my not do this often.
