air ride auto leveler

2001 Aurora.
My auto leveler is acting up. The air pumps up the rear end and stays up. Any idea how to fix this?

thanks

Had same problem found water got into the system and ruined the valves in the minature compressor. found identical compressor on a buick at junk yard just had to mount the buick compressor on the aurora mounting bracket. total cost 35.00 and 1 hour work, plus lots of junk yard time finding the compressor.

Sounds like your electronic level control sensor.

If the adjusting arm and electrics are connected OK and it still doesn't work then you may need to change it.
