Cadillac Repair: 98 cadillac rear air shocks, arnott industries, volt ohm meter

Question
1998 cadillac deville d'elegance, rear end sags when passengerss in back or weight in trunk. Unloaded can turn the key and compressor airs up to normal ride height. 180,000 miles. I would assume all is good but the shocks themselves. But someone said the compressor could be weak. I want to order from Arnott industries but not sure if I have CVRSS. I believe the shocks are base model. Any ideas?
