2004 Escalade Auto Level Control problem

[p91842]

I have a 2004 Escalade that the air auto level suspension air compressor is not running. Awhile ago it worked fine and could hear compressor running to maintain level of vehicle.

I have checked 40 amp, 30 amp, and 10 amp fuses associated with system and all are fine. Also there is no error message on dash.

Any ideas where to try next would be greatly appreciated.

Most likely its the exhaust solenoid on the ELC compressor assy. It is not serviced by itself and requires the entire compressor assembly to be replaced. If you can access the plug for the compressor, find the two wires from the exhaust solenoid , blue wire and grey wire if I remember right, and measure the resistance. If it's open or reading in the mega ohm scale, it's bad. Also check the air bags on the shocks, they wear and develop cracks and leak, causing the compressor to run all the time and burn it up.
