What Is an Air Suspension Compressor? The air suspension system works by pumping compressed air into air bags or springs made of textile-reinforced rubber via compressed air lines. The air compressor is an electric or engine-driven pump that’s usually attached to the car frame and found under the hood. It draws in outside air, compresses it, and uses the compressed air to fill the air springs to “lift” the vehicle’s chassis from the axle. The main reason a compressor fails is due to being overworked and burning out.Usually,when it is having a problem,a few symptoms will be produced that can alert driver of a potential issue that should be serviced:Vehicle riding lower than normal;Abnormal noises during operation such as excessively loud clicking, whining, or grinding;The compressor won’t come on. If you have these problems on your vehicle’s suspension, please inspect if the vehicle needs an air suspension compressor replacement. Signs that your air compressor needs to be replaced include Usually, when the compressor is having a problem, a few symptoms will be produced that can alert the driver of a potential issue that should be serviced. The first sign you should look for is if your vehicle is riding lower than normal. Air systems work by using pressurized air from the air compressor. A worn compressor will not be able to inflate the air springs adequately, which will make your car riding lower than usual. Another sign you should look out for is if there are unusual noises when you use your air system. Loud clicking, whining or grinding may indicate that there's something wrong with your compressor's motor or fan. If you keep running your car with a malfunctioning compressor, you are damaging it beyond repair. For exact years and models, please check compatibility.
