On my 2001 expedition I have 2 of them. One just under the front bumper, near the middle, but closer to the passenger side, and one under the truck, directly below the driver side seat, against the frame. They are like a one way valve for the air, but are a sensor for air pressure as well. A check valve of sorts. When they malfunction, your air ride wont have the right amount of pressure. My front one started to leak air and thus my compressor was constantly coming on to adjust for lower pressure in the front air shocks. I thought that my new shocks had failed already, but further research showed that it might be that solenoid. I replaced it and problem solved.
Sometimes you see the rear end lower then the front and that may be caused by one of three things.
1 - rear bags may need to be replaced, leaking air
2 - leveling valve for rear bags is not working properly or at all, or needs to be adjusted.
3 - solenoid is malfunctioning. the one under the drivers seat, against the frame.
I also found out that the solenoid can only be purchased through your dealer. I was not able to find any after market places to buy one. The cost of mine was $101.93 from Ford in Canada.
I hope this helps
In a 1999 Lincoln Navigator, the fuse for the air suspension relay is located in the fuse box under the hood. Specifically, you should look for the fuse labeled "Air Suspension" or "Suspension" in the fuse panel. If you’re having trouble locating it, consulting the owner's manual can provide a diagram for the fuse layout. Always ensure the vehicle is turned off before checking or replacing fuses.
If you have figured out where it is leaking from then here is a link to check out. I haven't used these people yet, but I am planning on it if I need to replace the air shocks in the front...
98 navigator (230)hp is 10.3sec 99 navigator (260)hp is 9.6sec 99-02 navigator (300) is 7.7-8.6 03-04 navigator is 10.3 with the 99-02 navigator engine 05-60 navigator is about 8 with the 04f150 engine 07-now navigator is 7.8-8.8
yep, just bagg it like i did my 99' Lincoln town car with 10-switches(air-ride suspension) rides better than factory!!!!
Under the windshield washer fluid resivour on the lefthand side.

Two wheel drive with standard suspension ( 26 gallons ) Two wheel drive and 4X4 with rear air suspension ( 30 gallons )
2 wheel drive - ( with standard suspension ) - 26 gallons 2 wheel drive - ( with rear air suspension ) - 30 gallons 4x4 - 30 gallons
No, a bad rear sensor to an air suspension compression would not directly make a motor not work. It can cause a battery to drain which would cause starting issues.Ê
Take out the battery.
im haveing the same problem on a 99 the code is for the frount pneumatic failure still trying to fint out what part
Disconect the battery or jack the car up under the suspention.
