How Do I know If My Seville (4.6L) Air Suspension is failing?

If you think your Cadillac Seville is not meeting and maintaining its appropriate ride height, look for these signs of a failed or leaking air suspension system. You will want a bad suspension fixed before total failure sets in, because other major components can wear out if you don’t. The most noticeable sign is a sudden uneven height between the right and left sides of the Seville. Typically the rear end will sag while the front end remains inflated. Sometimes there’s a slight lean from one side to the other. Maybe the Seville looks like it’s squatting down lower than it should be. If there is an illuminated air suspension warning light on the instrument panel, it’s safe to assume you’ll need a repair. If the air compressor has stopped working or is running too often, a replacement is in order.

Suspension Components List

1998-2004 Cadillac Seville Shock Absorbers (x2)- a metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.   1998-2004 Cadillac Seville Electronic Struts (x2)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. The Cadillac Seville's struts, while having coil-springs, use an electronic signal to stiffen or soften the dampening of the strut.   1998-2004 Cadillac Seville Coil Springs (x2)- Coil springs hold the vehicle up but be careful, they are rated for and designed to work with the rest of the suspension system, so when you change air shocks to passive shocks, then you will need a different rated coil spring that works well with the new type of shocks.   1998-2004 Cadillac Seville Height Sensors (x2)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.   1998-2004 Cadillac Seville Air Lines- tubes that run from a compressor (air suspension) to the air struts which carry pressurized air to the air bags components in order to adjust the height of the vehicle, respectively.   1998-2004 Cadillac Seville Solenoids (x4)- usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor.   1998-2004 Cadillac Seville Compressor- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.   1998-2004 Cadillac Seville Dryer Assembly- used to keep moisture out of air lines and air springs in order to prevent freezing and internal cracking of these parts. Once air suspension starts leaking, moisture will build-up throughout the air system. Moisture damages the air suspension from the inside. The dryer will need to be replaced in order to eliminate the moisture and prevent any further damage.   1998-2004 Cadillac Seville Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle's correct ride height.   1998-2004 Cadillac Seville O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
