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)
  • Damaged rear air spring(s)
  • Battery junction box (BJB) fuses 20 (30A), fuse 27 (5A), and fuse 111 (50A)
  • Loose, corroded, or disconnected connectors
  • Air suspension service switch is in the OFF position
  • Damaged solenoid valve(s)

-------------------------
I fthis does not help, the dealer can hook up his diagnostic equipment and download fault codes. Good luck. Please give best rating if this helps.

Here is how to tell if system is working.Get into the vehicle and close door. Set ignition switch to on position and move the gear shifter to neutral. After a few secs. you should hear the compressor turn on. If it comes on then put shifter back to park leave ignition on and exit vehicle. Compressor will stop when you open the door but should start back up in a couple of secs. after you close the door. You can then walk around the vehicle and listen for leaks.
If compressor does not come on there are 3 fuses and a solid state relay that controls it along with the module.
The 3 fuses are no. 109(50amp) in the battery junction box under hood.This is the direct feed to compressor thru the solid state relay. The other 2 fuses are located in the interior fuse panel and they are no. 6 (5amp) and no. 12(15amp).
What we usually see though if compressor does not run is either a bad compressor or the solid state relay. They both are rather expensive so I would have an experience tech look at it then.
However If you feel confident enough and have a voltmeter or test light respond back and I will tell you which wires to check.

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!!!

SOURCE: need to know the location

those airbag suspension systems are junk. you are going to spend more than the value of the car fixing it and then it will just go bad again in a few years.

take a look at this site, permanent fix for the whole system.

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.

I have a 2004 lincoln navigator and i was wondering where does a air suspension relay switch go



  • The suspension relay is behind the right headlight. Check for corrosion first. This is common with this relay. Sometimes cleaning off some corrosion and a few taps on the back will make it work again. Use some dielectric grease when installing the relay. You won't have corrosion issues anymore.

Okay the switch is in the back trunk area(I know it a SUV) in the back where you access the jacking tool youll see the switch make sure its on. Now some Navigator some have a shrader valve to pump up the suspension on the front area on driver side. As for the relay you might have to use a enhance scan tool to command it.By the way do you have a misfire?because if there is a misfire it will not inflate or a ABS light on? thse will also cause the suspension to not inflate

Where is the air ride suspension relay on a 2004 Lincon Navigator?


On my 04' Navigator the relay is attached to the bracket that holds the pump. The relay is square and has a cover that you need to remove to see it. The relay is located behind the passenger headlight. You can see the relay location without removing anything. The dealer told me it was a relay with aluminum cooling fins, this was incorrect for my Navigator.
