I have new air shocks in the rear and the compressor is no longer working. Anyone have a schematic of the system? I need the electrical layout and any help I can get.

its a 12 volt circuit that the compressor is powered by. The height sensor triggers the compressor to run. The height sensor is mounted to the body frame in the rear of the vehicle. The relay for the height sensor is under the rear seat left side. here is some steps to test the height sensor.

Turn ignition Off, then On. This will reset height sensor timer circuits.
Raise vehicle on hoist. Ensure rear wheels or axle housing are supported and that vehicle is at proper trim height.
Disconnect link from height sensor arm, then ensure sensor wiring and harness ground are connected properly.
Move sensor arm upward. There should be a delay of 8-15 seconds before compressor turns on and shocks start to inflate. As soon as shocks start to fill, stop compressor by moving sensor arm down.
Move sensor arm down below position where compressor stopped. There should be a delay of 8-15 seconds before shocks start to deflate and vehicle lowers.
