SOURCE: lincoln navigator air suspension is all the way down

that should not happen. Did you turn the switch off in the back for the suspension? Did you do something else at the same time, like check the spare tire for air pressure?

I have info on 2003 navigator 4 wheel air suspension. Maybe similar

SECTION 204-05: Vehicle Dynamic Suspension — 4-Wheel 2003 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION 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
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.

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.

------------------------------
Principles of Operation
The 4-wheel air suspension (4WAS) module commands changes in vehicle height that are necessary for both the load leveling and the vertical height adjustment features.
The 4WAS load leveling feature automatically makes adjustments in vehicle height so that the vehicle is always at trim height, and that constant front-to-rear vehicle attitudes are maintained over the load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle left and right sides for the 4WAS system are restricted to what can be reliably achieved with three height sensors.
The height adjustment feature has three vehicle heights within a two-inch span:
Kneel height — improves the ease of entering and exiting by lowering the vehicle one inch below the trim height in the front and rear when the vehicle ignition is in the OFF or LOCK positions and the vehicle is stationary.
Trim height — normal vehicle ride position; vehicle moves to trim position when the ignition is ON, when the transmission is initially shifted to DRIVE or REVERSE mode, when all doors are closed or when speed of more than 24 km/h (15 mph) is detected.
Off-road height — improves ground clearance by raising the vehicle one inch above trim height in the front and rear when the vehicle is at 4x4 low modes and the vehicle speed is less than 40 km/h (25 mph).
The 4WAS module uses the universal bus protocol, (UBP), module communications network for sending and receiving various signals with the exception of speed, information from the three height sensors, and the air suspension service switch. For additional information about UBP, refer to Section 418-00 .
The 4WAS system holds vehicle height when any door or rear hatch is opened. The system stores front and rear vehicle height the moment any door is detected open. The system then maintains this height regardless of the addition or removal of a load. The system returns to its commanded height when all doors are closed or vehicle speed exceeds 24 km/h (15 mph).

-------------------------------
Air Suspension Service Switch
The air suspension service switch signal is needed to wake up the 4WAS module. Without the module receiving this signal, the 4WAS system is inoperative at speeds below 24 km/h (15 mph) and will not react when the vehicle is raised or lowered. At speeds above 24 km/h (15 mph), the system will be active as if the air suspension service switch is in the ON position.
Vehicles without message center When the air suspension service switch is in the OFF position and the ignition switch is in the RUN position, a "CHECK SUSP" will appear in the RH corner of the instrument cluster.
Vehicles with message center When the air suspension service switch is in the OFF position and the ignition switch is in the RUN position, the message center will display "SUSPENSION SWITCHED OFF"
-------------------------------------------
Inspection and Verification
  1. Verify the customer concern.
  1. NOTE: If the door ajar indicator is illuminated when all doors, liftgate, and liftgate glass are closed, the air suspension will not work correctly. Repair door ajar indicator; refer to Section 413-01 .
    Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Restricted suspension movement
  • Excessive vehicle load
  • Cut, severed, crimped air line(s)
  • Unmounted height sensor(s)
  • Damaged front air spring(s)

SOURCE: 2003 Lincoln Navigator air suspension

I would recommend going to strutmasters.com and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. Airbags and compressors are constantly having to be replaced. Also something alot of people don't know is that theses air suspensions are not meant to be in temperatures above 90 Degrees or below 40 Degrees. That is most of the world. The temperature will cause you to replace alot of bags. and typically when your replacing a bag you are going to have to replace the compressor to because the bag had a hole or small crack in it causing the compressor to over work and it will die. I posted the link below so you can take a look http://www.strutmasters.com/lincoln-suspension-parts-s/1.htm I hope I was of some help Good Luck!!!

2004 Lincoln navigator air suspension all the way down front and back if I was to jump the relay to turn compressor on should the truck start raising up unless compressor not pumping or a leak


no it wont. the air suspension works as a complete system. each air spring has an electric solenoid, each corner has an electric height sensor and then the compressor itself. just energizing the compressor will not open the solenoids or sensors both of which are needed to raise the vehicle. what is probably happening is a failure in the computing system for the suspension system. expensive to repair.

WHERE IS THE REAR HEIGHT SENSOR ON 2004 LINCOLN NAVIGATOR


Usually between the frame and the rear axles. A lever type device, should be fairly easy to locate. Check that the compressor is building air pressure and storage tank. Air bags not leaking and etc.

My Lincoln Navigator air suspension went flat after we replaced all four tires, it won't air back up...please help!!!


AIR COIL SPRINGS WILL DEFLATE AND BE DAMAGED IF YOU DID NOT TURN OFF AIR SUSPENSION SYSTEM BEFORE RAISING VECHICLE AND CHANGE TIRES IF YOU DONT TURN OFF AIR SUSPENSION IT WILL CAUSE AIR SPRINGS TO OVER INFLATE CAUSE AIR SPRING SPRING DAMAGE.

2004 Lincoln nave, rear wheels jacked up high, front wheels normal, rides real rough??? any thoughts???? Thanks,


Replace the air suspension with conventional shock/strut
conversions. The Air Ride System is not worth investing
time and money ,after the vehicle is 5 years old.
Too expensive to maintain ,and too difficult to diagnose

Next time buy the Ford version of the vehicle

My 04 navigastor dropped on one side about 3 weeks ago.check suspension was "not" on. The dealership replaced the ride height sensor and the solenoid on that side. When we got the truck back the check...


Constructive----I have a very complicate 2004 Linclon LS and relatives have the Navigator, and Expeditions,Etc.

These vehicles have so many issues, dealers are not an option, because of cost, and there inability to even find an issue,that fortunately, I have done my own repairs for 47 years and stayed up with the technology.

I would say unless you have a local shop and a few dollars left,to diagnose and repair that air ride system,which I don't see as a problem, I would recommend you replace the suspension with conventional parts ,such as strutmasters offers or other Mfg may have. That way eliminate the air suspension issues.
It is ten years old and you will have the rest of it's ownership ,making love ,to constant COP Ignition Coil problems and more,so you don't need to stay with suspension issues

You should no way be at a dealer, for any make or model vehicle ,after the warrantee runs out.
If you have deep pockets,want nothing repaired and as people have coined it,get ripped off (over charged) then a dealer will hook you up

Air suspension leveler not working


you will most probably find that the air compressor for the air suspension has dried inside the piston bore as the piston has a rubber "O" ring on it and once the lubricant dries out the piston won't slide up and down the bore.
The compressors are usually under one of the front guards

  • Loose, corroded, or disconnected connectors
  • Air suspension service switch is in the OFF position
  • Damaged solenoid valve(s)

  1. If the inspection reveals an obvious concern that can be readily repaired, correct the concern before continuing with Inspection and Verification.
  1. If the concern remains after the inspection, use the scan tool connected to the data link connector (DLC) to retrieve continuous diagnostic trouble codes (DTCs) and to execute On-Demand Self-Test diagnostics for the 4WAS module.
    • If the On-Demand Self-Test is passed and no DTCs are retrieved, GO to Symptom Chart to continue diagnostics.
    • If DTCs are retrieved, go to the 4WAS Module Diagnostic Trouble Code (DTC) Index in this section.
    • If the 4WAS module cannot be accessed by the scan tool, Go To Pinpoint Test A .
