There may be more underlying problems than you want to deal with. On the air suspension systems it can be very pricey and frustrating finding the problem with the car. My suggestion is to check out They offer conversion kits for your vehicle at a great price. I put one on my moms Navigator and she loves it! Of course she loved the fact that she saved money too.

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.

2008 lincoln navigator check air suspension rear

A technician or mechanic can check this, but the most common problems are:
1) An electrical failure of some part, for example the switch or the relay that activates the compressor, or
2) the compressor itself could have failed.
God bless your efforts.

Air suspension pump wont come on

Check what part of the air ride system was damaged
from the accident

I would guess a sensor or something in that area

All your doing is jumping power to the pump

Last night we came outside to see that our 2003 lincoln navigator suspesion had dropped completely.Is there a button or switch to activate this back to normal or does this mean the suspension broke ?Please...

Air suspensions on Lincolns...the bags are good for about 8 years, and this is 2011, soooo...but, there are a few things you can try. When you start it, do you hear the compressor running? If not, check the fuses and relay for the compressor, and there is a shut-off switch and reset button in the rear (check your owners manual) that may have tripped-try resetting it to see if that is all that is wrong. Is it down on all four corners, or just the front/back? All four probably is a little more involved, but if it is just one end, it is usually a damaged bag (cracks in the folds), an open soilenoid, or a timed-out compressor. If there is an air ride light on while the car is running, it is almost always an issue with the compressor itself.

2003 Lincoln Navigator: The air suspension is gone and I need to know which relay controls the module.

Go to ebay motors and check out the air suspension compressor for the navigator, Mine is starting to go as well, runs all the time and getting noisy. I talked to an expert that says they are easy to change out yourself.

My suspension is low at the rear ,what could be wrong

the most common problem in this truckr and the Ford expidition is that the rear suspension air springs are leaking, they last about 75,000 miles, less on really rough roads.

2001 lincoln navigator rear suspension?

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.
