Question about 2004 Lincoln Navigator

2004 Navigator air suspension randomly comes on

Hello! I'm problem is this: After the initial activation of the air suspension during start up the motor will randomly activate/turn on while at a light, driving, turning, etc. Also, the motor is noisy and makes a ratteling sound, not the way it sound when if purchased the vehicle new. I thought I read something about the more possible being loose or there maybe some kind of leake but I cannot find the forum. Hope it's something minor & a quick fix. Someone help please!!!

There have been several problems about air suspension. There is a diagnostic plug to test this system. I can not tell you about independent shops having the tools, but try Autozone or Oreillys and see if they can scan the air suspension. If not, it must go to a dealer.

The airpump units are available at Salvage yards. However, a diagnostic test will quickly show which sensor or air suspension bag is leaking. There can be high pressure, so lines must be disconnected with care.

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 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

The suspension air compressor does not come on


Theo if the suspension air compressor doesnt come on it must be that your air is about to go out or it already has. How is your car acting? Is it low to the ground, kinda droopy?
