It sometimes will drepress in the rear when parked on an upgrade and sometimes it doesn't depress at all. having checked for bag and tubing leaks to no avail. What the solution here?

Leaks can be difficult to find in these systems. They could be in the air springs themselves, the air lines etc... not to mention you could have a ride height sensor that is malfunctioning or the control module. A lot of people are converting these old cars from the air ride suspension system to a standard passive coil spring conversion. A high quality, powder coated, American steel coil spring is DESIGNED to last the LIFETIME of the vehicle. http://www.strutmasters.com offers conversion kits with a lifetime warranty so youwon't have to worry about your suspension again. Give them a shot.. it definately beats the dealer price of around $1200 to fix your air ride.

You need to use soapy water in a spray bottle around the rubber fold of the air spring (bag) look carefully you'll see small bubbles (foam) you might have one front and one rear leaking. This is if it goes down over night as they each are sealed off by solenoids. If it goes down while the key is on then the plumbing might be leaking

Where exactly is the switch for the air suspension compressor on a 2006 Buick Lucerne CXL?


The automatic level control (ALC) system maintains a desired rear suspension position under all types of towing, hauling, and loading conditions.
The system uses the electronic suspension control module (ESCM), ALC relay, ALC compressor assembly, air dryer, air lines, LR and RR shock absorbers with integral air chambers, LR and RR suspension position sensors, exhaust valve, driver information center (DIC), and the serial data circuit to perform the system functions.
What switch ? there are sensors at the wheels that control the system .

The air suspension system in the rear end is over inflated. How do I remove excess air from it?


These systems can be read by a scanner with this function for air suspension. Since some cars have what is known as dump valves to bleed out the air, this valve could be stuck. Usually located somewhere under drivers front wheel well by front air deflector. Just follow air lines.

The system needs to know that every door and the trunklid are closed.

I have 97 mark viii n I c that everytime I get out the front end is always on the ground but it do rise up when I start it


Your mark viii has a air ride system. and as you drive, it has a pump under the hood. well over night it leaks down. then when you crank the engine .this pump will come on and air up the air ride system.kind of like a tire.But if just the front goes down ,Then you have a leak at the 2 front bags or lines, or connections. to find the leak try some soap in a spray bottle. after the bags are fully aired up and the engine off.some Lincolns leak worse the way they sit. it could leaking in a few places,that is what the soap is for.you can buy every part for that system from, Air Suspensions out of Orlando FLA 1-800-251-8993.plus diagrams

This is normal operation for this vehicle, the air in the air ride suspension system is designed to do this. After the vehicle sits, the air ride suspension will slowly release the pressure in the system until the vehicle is started again, and the air ride will level itself out again.

Hope this helps...

I had my rear suspension fixed but noticed when I park the front end goes down only when parked. It raises when I start the vehicle.


I think this car has air assist ride. Settles at rest, raises at some speed or upon start. Based on my assumption and what you said you had done, I would speculate that the rear suspension air control was not incorporated into the system.

This is a question you should ask your mechanic. BTW - I am not a Lincoln mechanic.

I have a 1998 ford expedition eddie bauer with front air bag suspension and after driving for about 45 minutes the air suspension light comes on. what's the problem and how do I fix it


here's some info. Do you have a warning light on or does it say "Check Susp"?

Control Module
NOTE: The 4-wheel air suspension (4WAS) control module is also used for the rear air suspension (RAS) system. The internal processor recognizes external circuitry to determine if it is installed in a 4WAS or a RAS system.
NOTE: The air suspension control module is calibrated with information from the air suspension height sensors. A new or swapped air suspension control module requires the ride height adjustment calibration process to be performed.
A microcontroller-based electronic air suspension control module controls the air compressor motor (through a solid state relay), and all system solenoids. The air suspension control module also provides power to front and rear height sensors. The air suspension control module controls vehicle height adjustments by monitoring the two height sensors, vehicle speed, a steering sensor, acceleration input, the door ajar signal, transfer case signals, and the brake pedal position (BPP) switch. The air suspension control module also conducts all fail-safe and diagnostic strategies and contains self-test and communication software for testing of the vehicle and related components.
The air suspension control module is mounted in the passenger compartment inside the instrument panel, above the radio and temperature controls. The air suspension control module is interchangeable between the RAS and 4WAS system.
The air suspension control module monitors and controls the system through a 32-pin two-way connector. The air suspension control module is keyed so that it cannot be plugged into an incorrect harness. There are two sides of the harness connection to the air suspension control module. Each is uniquely colored and keyed to prevent reversing the connections.
Solenoid, Air Spring
swj~us~en~file=ani_caut.gif~gen~ref.gif WARNING: Never rotate an air spring solenoid valve to the release slot in the end cap fitting until all pressurized air has escaped from the spring to prevent damage or injury.
The air spring solenoid:
  • Allows air to enter and exit the air spring during leveling operations.
  • Is electrically operated and controlled by the air suspension control module.
  • Is only replaced as a unit.
Air Suspension Diagnostic Connector
The air suspension diagnostic connector is used to aid the technician in diagnosing the air suspension system. It is also used to vent the system of compressed air when air suspension system components need to be repaired or replaced. The air suspension diagnostic connector is located under the steering column.
Steering Sensor
The steering sensor is mounted inside the passenger compartment on the steering column. It provides steering rate and position to the air suspension control module through two signals.
Pressure Relief Valve
The pressure relief valve (PRV) protects the rear air suspension components by venting the system to a specific pressure in the case of a system malfunction. The system will decrease the pressure to an acceptable level to maintain vehicle height. In the normal operation mode with normal system pressure the PRV is constantly closed and does not have any effect on the system performance or function. The PRV is replaceable without any air lines.
The PRV is located in the rear of the vehicle on the middle of crossmember #5 as a part of the rear air line assembly.
