Question about 2000 Lincoln Navigator

2 Answers


Have a 2000 lincoln navigator, 4wd, and my rear air shocks are deflated. I parked the car for a few days, and then one day it raised back up, but then the next day, back down to the frame...both sides by the way. I took out the compressor and tested it with a couple wires hooked up to the battery and it came right on. Since both rear shocks are deflated, would it be a AIR SUSPENSION REAR MODULE, or something else, maybe a relay, or sensor? i HAVE THE SAME PROBLEM EXCEPT MINE HAS NEVER RAISED BACK UP. IS THERE A FUSE FOR THIS OR WHAT ELSE SHOULD I BE LOOKING AT?

First, you may have leaks in your bags, causing your suspension to drop. The other possibility is that your rear suspension level sensor is faulty, causing the suspension to readjust itself incorrectly.

Hello ddishman...sounds like you have a solenoid open causeing the air to purge from the system...the height sensor tell the control module if the vehicle is raised too high. The control module will open the solenoids in the struts, and open the solenoid at the compressor, this releases the air in the system.
Note: disable air ride if you plan on raising the vehicle and crawling under to troubleshoot loose sensors, etc....any sudden movement could cause the your navi to shift and fall off the jack stands.
Good luck...i hope this helps fixya.

SOURCE: I have a 2000 lincoln navigator, 4wd, and my rear

If you can get them inflated there is a switch on the passenger side that you can put in the **** off position till you get the problem resolved. Yet there is a part that is an inline part that can be leaking and must be replaced coast about $30.00. It is located in the engine compartment on the left side fender wall. It is in a airline that feeds to the Air suspension.What I did for a quick fix was a took the line apart place a 3/8 hose over it and clamped it. I have the part and never installed it because the above worked for me. Yet I do here the pump come on more often yet I was told the pump was bad. If you need to contact me email or call 386 252 9987 fax will pick up on the 4th ring. I have a busy day tomorrow but try me later on in the afternoon 4ish. But email with the time you would be calling or leave your number. This information I am giving you cost me $500.00 to get.

Check your rear shocks. On the fender, push with your body going down. Upon releasing, your car should go up and down one time then settle. If it goes beyond or hesitate to move, you have a problem with your shocks. I think you also have a problem with the shock absorber bush. It does not matter if you have a new or old shock absorber. The lifespan of the shocks depends on the way you drive on bumpy roads.

Why won't rear end raise up ?

I have a 2000 Lincoln Town car, had the same problem, it was the rear air suspension/shocks. They are air bags basically that levels your car and it cost about $300.00 for each at the dealer for parts and install but it also has its own motor that inflates and deflates these air bags and I also had to replace that and that cost over $400.00 installed at the dealer.

Rear air shocks 1998 lincoln continental deflate when parked

My Grandma marquis did the same thing, I thought that was normal, it slowly goes down when you shut it off and slowly goes up when you start it, It didn't hit the ground or anything, but then it finally did die altogether, years later, and then it hit the ground, so I got regular shocks back there and it rode fine, stayed level, it is now resting in the junkyard in a shallow unmarked grave. It was a nice car.

It could be the pressure sensor. Or there may be a leak in the system. And since the vehicle is parked, it may just be saving battery by not running the compressor that often. Bring it to a quite place, and let it fill up. Shut if off and crawl underneath, and listen for a hissing noise. Seals can leak so easily, exp if they dry out. And being nearly ten years old its possible you just have a bad seal on one of the air lines. Assuming it uses rubber seals on the lines.
