The are ride height adjusters the look like arms. they are mounted on the bottom of the struts and lower control arms that control the height The can be adjust but for the most part if the were working fine before then they need to be replaced. Make sure that there are no leaks in the system.

Already converted from rear air bags suspension to non air.. but now my steering isn't right. what can that be?


Probably something to do with ride height settings in computer trying to compensate for some reason, do you still have front air bag suspension? You could try removing fuse for suspension.

Rear air suspension will deflate but won't inflate. All fuses are good and the compressor relay has been replaced. Jumping out wires at the compressor relay will inflate and maintain height with the rear...


If it is easy to remove the sensor and the plugs are the same. I would try that. That will tell you if the sensor is bad(the rear will inflate). Or if it is the module. (It won't inflate).

The door problem could be a faulty switch/sensor inside the door latch. If the suspension warning light is on there is a problem with that system too.
The system should maintain standard height even with the door open in most cases. It may not increase height if you load the car and the door is not closed.

Can not get the new air ride compressor to come on


Make sure the trunk switch is turned on. Your doorjam and trunk switches are wired into the Air-ride. They must sense the openings are closed before the lift compressor will work.

There are level controls for height. If the car was put on a lift without the switch being turned off, the positioner may be stretched beyond working.

I just purchased a 1997 lincoln continental and the rear suspension deflates at night but when it is started in the morning,it reflates. Is this normal?


it should deflates only at trim height and shld stay at that level considering that there is no leak on the rear air suspension. Most probably leaking rear air suspension is the problem. The system works up to 45 minutes only after ignition off and will maintain the trim height

My 1995 continental has severe ride problems bounces on every bump in the road front end sits low and rear seems normal


Sounds like the front "air ride suspension" is out.
That works off rubber bags built into the springs. If one or both has developed a leak/hile, it lets the front end (or rear or both) drop to ride on the bottom of the suspension.
Get the wallet out. It's expensive.
Sorry :-(

I have a 1994 lincoln continental car. Hoe do I replace the suspention drier?


why do you want to replace it? As air is exhausted through it, it dires it out for the next use. it's part of compressor assembly.

1996 cont'l The air suspension system includes the following major components:
  • Air compressor to supply air to the air springs (part of front spring and shock and rear spring and shock absorber assemblies
  • Front spring and shock (3C098) and rear spring and shock absorber (5A965) at each corner of the vehicle
  • Four linear air suspension height sensors (5359): two rear and two front height sensors to maintain the vehicle at the proper ride height; only LH rear height sensor is used for air suspension.
  • Dual-mode front spring and shock and rear shock absorber assemblies with internal actuator.
All system functions are controlled by vehicle dynamics control module (5A919). This control module receives inputs from several different sources. These inputs include:
  • vehicle speed via multiplex communication network
  • ignition switch position
  • door position via multiplex communication network
  • height sensor position
  • air suspension service switch
  • engine rpm via multiplex communication network
  • ride and steering personality settings via multiplex communications network
Communications monitor system operation and allow diagnosis of any concerns that may develop in the system. System monitoring for the driver's use is provided through the instrument panel mounted message center indicator (10D898).
  • Diagnosis communication for the service technician is provided through the data link connector (14489) (DLC) under the instrument panel and Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent.
The message center indicator will display AIR LEVELING DISABLED or CHECK RIDE CONTROL if the suspension system is not turned on or the vehicle dynamics control module detects a concern. If air leveling system disabled is displayed, check that air suspension service switch is in the ON position.
----------------------------------------------------------
Solenoid Valve Vent The vent solenoid valve operates as follows:
  • The vent solenoid valve allows air to escape from the system during venting corrections.
  • The valve is located in the air compressor cylinder head and shares a common electrical connector with the motor.
  • The valve 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.
  • Air leakage past the valve tip is prevented by an O-ring seal.
  • The vent solenoid valve opens when a corner of the vehicle is high and the vehicle dynamics control module (5A919) determines lowering is required.
  • When the vent solenoid valve is opened, it provides an escape route for pressurized air.
  • However, the vehicle will not lower unless the air spring solenoid valves (5311) are also opened to allow air to leave the springs.
  • Lowering the vehicle corners requires the vehicle dynamics control module to open two solenoid valves, the vent and one air spring solenoid.
  • Air is exhausted from the spring and vents through the compressor air drier (5346).

EXPEDITION REAR AIR RIDE PROBLEM


do you have just rear air suspension? here's rear only. 4 wheel different. Deler an run a diagnostic test with WDS machine and get fault codes.
-------------------------------------------------------------------------------------
The air suspension system is designed to improve ride, handling and general vehicle performance for static, on-road and off-road driving conditions:
  • 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, the 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 the 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) 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 air springs with air spring solenoids.
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 or the vehicle speed exceeds 16 km/h (10 mph).
----------------------------------------------------------------------------------------
Air Suspension Height Sensor
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 (3.2 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 (3.2 in) 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).
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

Where are the leveling sensors located on a 2003 Navigator?


There is one at each wheel. here is some info

Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:
  • service switch
  • control module
  • two front height sensors
  • one rear height sensor
  • compressor and drier assembly (includes vent solenoid)
  • air lines
  • front and rear air spring and shock absorber assemblies
  • four air spring solenoids
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: The service switch for the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the jack storage area in the rear of the passenger compartment. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations.
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.
