Well, we're back at Airmatic. I wonder why?
Beautifull cars with substandard suspenssion system called Airmatic.
To address your issue: When you press the button on the dash (to lift the car), the car does nothing, correct? That would indicate a blown fuse #32, faulty relay, or fried compressor. So you need to check it in that order. Get FEW 40amp fuses, and start there. If the fuse blows as soon as you try to raise the car,....your compressor is toast! Time to order a new relay and the pump. Once you replace that, you can concentrate on finding the leaks on the shocks. You have several options there. Stock shocks, Arnott air shocks, or Arnott coiled replacement. Doing the top seals might be another option, but it's a "bandaid" that will help until the bladders fail (unless bladders are your problem to begin with!).
My advice: Get the compressor going, replace the shocks (if needed), and enjoy the car. The reason I said "if needed" is because you are not sure at this point that the shocks are leaking. It may be leaking from the valve, or any of the PVC hoses, but to find what's leaking, you will need to pressurize the shocks, hence......get the compressor going first.
If I was in the room when they designed this system, I would not let them! If the directive "from above" was to make it work, I would at least insist on putting an additional nipple on each shock, that the owner could reach with a hand operated air pump (like some of my motorcycles have on the front fork!), and inflate the shocks manually in the emergency (of course it would not work if the bladders are torn, but it would work in the case of failed compressor, valve, or lines). Once the car is sitting on the tires, there is no other help but the towtruck, and that's just poor engineering.
