SOURCE: AIR SUSPENSION PROBLEMS FOR 2000 LINCOLN TOWNCAR CARTIER

I have serviced these in the past and it will probably be a combination of things. I just a few weeks ago fixed a 1999 with the same problems. Generally from past repairs, the electric pump has been working overtime to compensate for leaking rear air shocks. The best solution is to replace them both, not a cheap repair, the pump around 275.00 and each shock arount 275.00.
Just with every thing over time things fail, the rear shocks develop leaks over time/weather cracks, they are easy to check, soapy water will identify this as the problem. If you can get under it enough to spray around the bottom of the shocks when they are inflated. These systems are computer controlled and if you have the proper scanner you can check the system out for eletrical problems easily. My past experiences with these suspensions as almost always the shocks and pump.

SOURCE: rear air suspension is not at level left is higher than the right

I have the exact same problem but my Left side is "Lower" than the right side.... Go Figure, Let's switch Solenoid's... Lol. I haven't seen a fix for this yet... there is 1 ride height sensor bolted to the rear but it's for both sides. the following site seems to be recommended by most Expo owners on all of the ford forums.. Check them out.

SOURCE: the rear suspension air bags no work

There is a ON/OFF switch for the air bag suspension system. It's should be under the dash on the front passenger side, or back trunk where is behind a plastic cover. Check to see if the switch solve the problem. If not, the air compressor maybe bad or the air bags may have a hole.

SOURCE: Removing rear air suspension on GMC Envoy

Just behind right rear tire up in the wheel well. Air inlet is inside right rear quarter near the accessory inflator. Compressor runs 3 lines one for the accessory inflator and one for each air bag.
THere are also 2 sensors, one on each trailing arm that senses load and then raises and lowers accordingly.

Rear Air Suspension won't air up


take the sensor arm loose and manually operate it, when it is up, it thinks the suspension is low. Spray the bags and hoses with soapy water to find any leaks, dawn dish detergent works well. repair any leaks. If no leaks manifest, take a hose loose and see if you are actually getting air pressure from the air pump. Just because it is running, doesn't mean it is supplying pressure.

Why won't rear end raise up ?


I have a 2000 Lincoln Town car, had the same problem, it was the rear air suspension/shocks. They are air bags basically that levels your car and it cost about $300.00 for each at the dealer for parts and install but it also has its own motor that inflates and deflates these air bags and I also had to replace that and that cost over $400.00 installed at the dealer.

Air bags suspension won't inflat. Checked all fuses & air suspension switch. What can the problem be?


Probably failed seal or air bag leaking air. Check again and try to see if this will do the trick. Sometimes pvc line could fail to deliver air to the bag too!

There is some kind of pump on the rear drivers side near the spare tier what is it and why is it makeing a loud vib sond?


Your vehicle is apparently equipped with Automatic Level Control Suspension (ALC). The thing you hear running in the rear driver's side is the air compressor that pumps up your air suspension. It is normal for this to run occasionally. Sometimes they seem a little loud. That's why they mounted it all the way in the rear and used rubber bushings to secure it...so you won't hear it running while you are driving. If it is running too much, it can be a sign that your air suspension components have air leaks. If it seems to run constantly, you need to get your suspension system checked because the pump will burn itself up trying to keep the leaky suspension inflated. VERY common as well as VERY EXPENSIVE to fix if not taken care of promptly.

If it just runs for a minute or two and shuts off and doesn't come back on for a long time, don't worry about it - this is normal. It SHOULD run for a while if you have the ignition key turned on and you load something heavy in the back of the vehicle.

The rear suspension air bags no work


start here

The air suspension system is designed to improve ride, handling and general vehicle performance for static, on-road and off-road driving condition:
  • Ride is improved by using an air type spring (the soft ride is inherent).
  • Handling is improved by maintaining constant vehicle attitude.
The system consists of unique rear air springs, air compressor, air lines, air spring solenoids, height sensor, air suspension control module, attachments and associated signals derived from both driver and road inputs. With these components and signals, the air suspension control module commands changes in vehicle height that are necessary for the load leveling features.
The load leveling feature rear air suspension (RAS) systems shall automatically make adjustments in vehicle height so that the vehicle is always at trim height and constant front-to-rear vehicle attitudes are maintained over the expected load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle's left and right sides for RAS system shall be restricted to what can be reliably achieved with one air suspension height sensor.
The system uses one air suspension height sensor, a steering sensor, generic electronic module (GEM) transfer case inputs, and other vehicle sensors to measure driver and road inputs. The system changes vehicle height using an air compressor, two air lines, and the use of an air spring with an air spring solenoid.
The air suspension system holds vehicle height when the rear hatch or any door is opened. The system stores rear vehicle height the moment any open door is detected. The system then maintains this height regardless of the addition or removal of a load. The system will return to its commanded height when all doors are closed and the vehicle speed exceeds 16 km/h (10 mph).
Air Suspension Switch
The air suspension switch is located behind the RH kick panel on a mounting bracket. The switch interrupts power to the air suspension control module.
The air suspension switch supplies a signal to the air suspension control module. Without the air suspension control module receiving this signal the load leveling system is inoperative and will not react when rear of the vehicle is raised or lowered. If the air suspension system is disabled by turning off air suspension switch, a "CHECK SUSP" will appear in the RH corner of the instrument cluster with the ignition in the run position.
Air Compressor
The RAS air compressor:
  • Is not interchangeable with four wheel air suspension (4WAS) compressor.
  • Consists of the compressor and vent solenoid; neither are replaceable as individual items.
  • Is mounted in the engine compartment between the washer fluid bottle and headlamp (RH front corner).
  • Is a single cylinder electric motor driven unit that provides pressurized air as required.
  • Is powered by a solid state relay, controlled by the air suspension control module.
  • Passes pressurized air through the compressor air drier that contains silica gel (a drying agent). Moisture is then removed from the compressor air drier when vented air passes out of the system during vent operation.
  • Air drier has a single port and is not interchangeable with 4WAS compressor air drier.
  • Air drier may be replaced separately.
  • Incorporates a snorkle that may be replaced separately.
The vent solenoid:
  • Allows air to escape from the system during venting actions.
  • Is located in the air compressor cylinder head.
  • Has a 160 psi internal relief valve.
  • Shares a common electrical connector with the air compressor motor.
  • Is enclosed in the cylinder head casting, which forms an integral valve housing that allows the valve tip to enter the pressurized side of the system.
  • Has an O-ring seal that prevents air leakage past the valve tip.
  • Opens when the air suspension control module determines lowering is required.
  • Provides an escape route for pressurized air that opens when system pressures exceed safe operating levels.
  • Is replaced with the air compressor as a unit.
Air Spring
RAS vehicles use air springs in the rear. The air springs provide a varying spring rate proportional to the systems air pressure and volume. The air suspension system regulates the air pressure in each air spring by compressing and venting the system air. Increasing air pressure (compressing) raises the rear of the vehicle while decreasing air pressure (venting) lowers the rear of the vehicle. Vehicle height is maintained by the addition and removal of air in each air spring through an air spring solenoid installed in the upper spring cap and energized through the air suspension control module.
The air springs are mounted between the axle spring seats and the frame upper spring seats.
The two air springs replace the conventional rear coil springs.
Air Suspension Height Sensor
When the air suspension height sensor indicates that the rear of the vehicle is lower than trim under normal driving conditions, the air compressor will turn on and pump compressed air to the air springs. When the sensor indicates that the rear of the vehicle is raised above trim under normal driving conditions, this will cause the air to be vented from the air springs to lower the vehicle back to its trim height level.
One air suspension height sensor is mounted on the vehicle. The air suspension height sensor sends a voltage signal to the air suspension control module. The output ranges from approximately 4.75 volts at minimum height (when the vehicle is low or in full jounce), to 0.25 volts at maximum height (when the vehicle is high or in full rebound). The air suspension height sensor has a useable range of 80 mm (3 in) compared to total suspension travel of 200-250 mm (8 to 10 in) at the wheel. Therefore, the air suspension height sensor is mounted to the suspension at a point where full rear suspension travel at the wheel is relative to 80 mm of travel at the air suspension height sensor. The air suspension height sensor is attached between the No. 5 frame crossmember (upper socket) and the panhard rod (lower socket). Replace the air suspension height sensor as a unit.
Compressor Relay
The compressor relay is energized by the air suspension control module to allow high current to flow from the battery to the compressor motor.
  • A solid state relay is used in the air suspension system for air compressor control. The relay incorporates a custom power metal oxide semi-conductor field effect transistor (MOSFET) and ceramic hybrid circuitry. The relay switches high current loads in response to low power signals and is controlled by the logic of the air suspension control module.
Air Suspension Control Module
NOTE: The 4WAS air suspension control module is used for the RAS system. The internal processor recognizes external circuitry to determine if it is installed in a 4WAS or a RAS equipped vehicle.
NOTE: The air suspension control module is calibrated with information from the air suspension height sensor. A new or exchanged air suspension control module requires a ride height adjustment calibration process to be performed.
The air suspension control module controls the air compressor motor (through a solid state relay), and the air spring solenoids. The air suspension control module also provides power to the air suspension height sensor. The air suspension control module controls vehicle height adjustments by monitoring the air suspension height sensor, 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 monitors and controls the air suspension system through a 32-pin two-way connector. The air suspension control module is keyed so that the air suspension control module 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.
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 steering column.
