You have several componets. Front airs shocks, compressor and rear air bags, level switches at each leftshock.If you want to just stop the compressor either remove the relay or just unplug the compressor. It is on the passenger side front right under the washer resevoir. Several companies make parts to replace the stock system. You will need a OBD II code machine to defeat the "check LVL" code that will flash on the dash.
