It sounds to me like your compressor got killed. What probably happened is that the airbag got a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag killed the compressor. I would recommend going to 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. I added the link below so you can check it out. 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.

Air suspension is up in rear of car. how do I

If I'm understanding the question correctly, the problem is the rear is stuck in the "jacked up" position. If you start the car and after a short while the check suspension message comes on, most likely the problem is a rusted corroded vent solenoid in the compressor. When this solenoid sticks closed, the air can't vent to the atmosphere. Keep in mind this problem is a very common one and the root cause is excessive moisture in the system. While replacing the compressor/dryer would get it working normally again, if the moisture problem isn't addressed, the replacement compressor WILL BE short lived as well. RECAP: Short term....replace the compressor/dryer. Long Term....replace the compressor/dryer, then in 30 days replace the dryer only....then again in 6 months. Want to be done it those problems forever? Do a Lincoln Town Car Air Suspension Conversion on your car and be done with those expensive repairs forever!......for less than the cost of a replacement compressor.

1997 ford windstar rear air suspension problem

Yes, you may be able to find an Autozone or Oreilys with a scanner for the suspension system. It can easily be a height sensor, but to know if it is a bad connection or only the sensor takes testing equipment.

You could be Okay at the back end and the equalizing system to the compressor is failing to update. Unless you are familiar with the voltage the system uses, you may fry something with 12 volts.

Troubleshooting Suspension failure 2000 Lincoln Navigator

I have owned several air suspension vehicles. My Expedition was similar to yours. You may want to try the 4x4 switch because it will raise the body 1-2 inches higher. Checking its fuse would not hurt.

On most of my vehicles the suspension would work end to end, raising the front first. You could have 2 issues with the suspension. There should be valving to switch the air to the rear suspension after the front is up. I would wait longer for the rear to catch up.

If I had to guess why the front lifts first it would be to get the front off of the curbs and sidewalks when you park so the bottom doesn't drag.

There is a diagnostic plug for the air suspension and sometimes Autozone or Oreillys have the scanner for that special plug. If not, some alignment shops and all dealers would have it. Also Ford parts are often the same as Lincoln and cheaper., Someone may make aftermarket parts at a better price.

The rear suspension is down on my 1999 Ford Expedition - Eddie Bauer. The cause: while out in the woods I came across a small dip which cause my back left wheel to lift off the ground. The suspension...

I had a 1999 Expedition. When you put the 4x4 on it raises the vehicle an extra inch or 2.
It may help to turn the 4x4 off. Two wheel drive is a lower air setting.
Your original pump may still be good. The problem can be in the front. The compressor is not filling the front suspension to the cutoff point. It will lift the rear after the front end is at running height. Since you lost the front end first, the remaining air bled out there and then the rear came down. Once you shut down the car the suspension was done, all the air was let go.
There are adjustment solenoids on the body but you need someone qualified to repair this.

Air suspension went down while driving the vehicle

the compressor is mounted down low in the left front behind the left headlight. it is powered by a large fuse in the under hood right side fuse panel. if the fuse is good.flip off the trunk suspension switch,jack up the rear wheels and check to see if the sencing arm that attaches to the rear end has fallen off it's pivot. if it is unattached it will drop both rear air bag pressures quickly.
good luck chris

Air Suspension plomlem

1. make sure the switch is on (under the passenger side dash board). 2. check to make sure the relay is good (black little box under the right front bumper. 3. there are two (that I know of) switches/sensors.  1 is behind the left front tire.  The other is up behind the spare tire.  Taking the spare tire off gives you tons of room to work with.  The sensors look like mini shock absorbers with black rubber and can be compressed and pulled easily by hand.  Moving those will simulate the suspension going up and down and should trigger the compressor. 4. if the compressor doesn't come on (and all the above is fine) it sounds like your compressor is bad and should be replaced.  I got one from Arnott Industries in Florida and they have been very nice to work with so far.
