compressor is located under the car. look under the driverside near the rear axle. I belive it is closer the the rear pass. floor board, but you can't miss it, it is mounted insidea metal box. I don't think you compressor is bad, maybe your shocks have a bad leak and need to be replaced, or you may have a bad leveling sensor, or the rod that connects the sensor to the car is not attached. The leveling sensor is mounted on the frame above the rearend, but you can't miss it either. There should be a little rod with plastic swivel sockets on each end that snap onto the sensor, and then the other end to the rearend. You can look for leaks with a spray bottle of soapy water. When yu spray around and you get a bunch of bubbles, then you found your leak. Search for leveling system, or air shocks, there is plenty here on this subject.
