There is a ball joint on the lower control arms of the suspension that allows a rod to connect to a ride height sensor and this is how it figures out what the suspension is doing and it uses a hydraulic system to change the suspension.
No it should not. They have a ride height switch, which cycles the compressor. You probably have an air leak in the system.
A person can reset the air ride suspension on a Cadillac Deville by disconnecting the compressor wiring harness from the compressor itself. This is accomplished by putting the vehicle on ramps.

The Level Ride Compressor on your '96 DeVille is located underneath the car near the right rear wheel. Just follow the plastic tube from the air-shock to pinpoint it.
On the air springs.

I had a problem with my 97 deville air ride and the fuse in the trunk labeled RSS was missing so I replaced it and the shocks started working.
it means your struts need to be checked and or replaced. the deville has an automatic ride control that eletronically controls the ride height of the vehicle front and rear. there are passive struts available from the dealer..or aftermarket air ride or passive systems available for it on the net. i suggest the dealer or a reputable mechanic do this as the electronic control has to be disabled if the passive struts are installed.
check your ride height sensor
the level ride air compressor is located under the hood.drivers side front fender well,right behind battery
