Here is how to tell if system is working.Get into the vehicle and close door. Set ignition switch to on position and move the gear shifter to neutral. After a few secs. you should hear the compressor turn on. If it comes on then put shifter back to park leave ignition on and exit vehicle. Compressor will stop when you open the door but should start back up in a couple of secs. after you close the door. You can then walk around the vehicle and listen for leaks.
If compressor does not come on there are 3 fuses and a solid state relay that controls it along with the module.
The 3 fuses are no. 109(50amp) in the battery junction box under hood.This is the direct feed to compressor thru the solid state relay. The other 2 fuses are located in the interior fuse panel and they are no. 6 (5amp) and no. 12(15amp).
What we usually see though if compressor does not run is either a bad compressor or the solid state relay. They both are rather expensive so I would have an experience tech look at it then.
However If you feel confident enough and have a voltmeter or test light respond back and I will tell you which wires to check.

Could very well be faulty relay, bad fusible link, or a fuse in general. You can trace the wiring or view a free repair manual at autozone.com to trace wires to find faulty device. You can use an ohmmeter or multi-tester to test relays and fuses.

could be faulty compressor which pumps up the suspension,is it leaking from anywhere,causing the pump to work too hard,has it just packed up,check fuses but probably compressor

SOURCE: need to know the location
those airbag suspension systems are junk. you are going to spend more than the value of the car fixing it and then it will just go bad again in a few years.
take a look at this site, permanent fix for the whole system.
