    I have a simular problem. I have a 2001 with the rear leveling system. I have replaced the air bags as well as the rear sensor. My problem is still the ride. I feel like I am in a lowerider with heated springs. No light is on and my compressor comes on like normal. Does the relay or module have any thing to do with this.

    Afternoon. I think I'm having a similar problem with my 2000 exp and I'm trying to figure it out on my own before bringing it somewhere to potentially get screwed...

    Basically, my passenger side rear drops either when driving and/or parked and the compressor would come on to inflate it. I thought there was a leak, but at times it holds pressure fine and doesn't drop and/or will inflat itself while parked and it would be fine..... It sounds like the vent solenoid is randomly venting itself when it shouldn't be if that makes any sense....

    ANY advice would be awesome...

    I have a 97, and i am experiencing this same thing.
    I bought a new compressor and had it installed but the darn thing keeps falling, and the ride is UNBEARABLE!
    I just dont know what more to do!

    I had a similar problem 2yrs ago- the front was sitting higher than the back and the ride was unbearable! Check Suspension light did go on and the problem was a bad compressor. switched the compressor and the system was good as new. You may want to test the electrical lines to the compressor to make sure there is power. If there's power sounds like you're having the same problem.

I am currently going thru this nightmare with this ford piece of ****. I would like to stick a bail out up a ford execs ***. Try going 12 volts to the compressor, if you get noise, and it is running, then it is a relay, which is located behind the pass headlight, in the front of the pass wheel housing. My current problem is that I can get the compressor running thru 12 volts, vehicle raises and is level, with no air leaks as the height holds. I believe I have either a defective harness or another bad relay. There are 2 little shock type adjusters, one is in the middle mounted to the rear axel, the other in the front, mounted to the drivers side upper c/arm. they pop off easily. pop one off, prp it so it senses a load and see if the vehicle raises. the reverse will induce a lowering. any other quesions, email me 2

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.

I have a 1999 Lincoln Navigator. My air suspension system is not working because the rear of my NAV is sitting low and the air suspension shut-off switch located under the dash board on the passenger side...

those systems are junk and not really repairable, any repair cost will far exceed the value of the car and it will just start leaking again. take a look at and consider buying one of their replacement suspensions for it. that will put an end to it once and for all.

Check suspension light is on

I believe this light comes on when there is one of several issues. Some symptoms are: Ball Joints worn, tie rod ends, vibration, bad tire(low Pressure also), alignment, pulling to left/right, shocks F/R check some of these and you may locate why light came on. Wayne

My 1995 continental has severe ride problems bounces on every bump in the road front end sits low and rear seems normal

Sounds like the front "air ride suspension" is out.
That works off rubber bags built into the springs. If one or both has developed a leak/hile, it lets the front end (or rear or both) drop to ride on the bottom of the suspension.
Get the wallet out. It's expensive.
Sorry :-(

2001 lincoln navigator suspension went out, vehicle is sitting low on rear tire

Hopefully just needs to be reset, those air susp r expensive. Some susp come with a switch to turn on and off could be on the left or right rear back look for it turn off then on if that does not work, disconnect p bat terminal for 5 min then reconnect. Listen for suspension should make some noise.
