suspension problem load leveling

I am having a problem with my wife's 1999 Eb expedition. It has the load leveling system on it. For some reason the rear will not air down. It is sitting up on the rear like it is jacked up. I don't know if it working on the front end either. When I turn on the engine I do not hear the compressor for the suspension turn on. When I shut her down I don't hear the suspension deflate. I checked for codes and there aren't any. Anyone have any idea of where I should start looking for diagnosing her? Anyone else with a problem like this? The truck has around 110k on here. I had a mechanic change one of the air shocks a few months ago. Also my wife put her in 4x4 a few days ago just to see if it works. She said she didn't notice any difference when in 4x4 so I am not sure if that effects the load leveling.

Yes. The switch is on. I also checked the maxi fuse and switched it with a good one. No difference.

I would disconnect the battery and see if resetting the GEM makes any difference.
