Re: 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.

The best way to fix Air ride issues is to get a conversion kit. We paid $200 online for ours and my husband installed the new parts. We were told fixing the air ride could cost upwards of $3000. Experience from several people told us that parts on the air ride go out quickly once it starts having problems. Ours rides just as well as before and we will never have another air ride problem again. Our Navigator is AWD 4x4.
Your problem is due to your car's air ride suspension being temporarily off line. This is likely because your air-ride suspension relay is blown. Simply replace the relay module located in a large black box under your hood. Take lid off of black box and find the air suspension module and replace. It will look like a square silver match box plugged into a circuit board. Unplugg it and replace it with a new one.
It sounds like one of your air bags could have blown. I would check them first. I would also suggest checking into a replacement non air conversion kit from Strutmasters. I replaced the air system on my 2002 Navigator and saved a lot of time, money and headaches.The lines on my navigator had holes in them and I replaced the compressor twice before I realized it. Very costly. Avoid all the hassle and check out Strutmasters.
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.
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.
Remove battery, remove windshield washer bottle, remove air compressor and disconnect both air lines from the compressor dryer. Make sure compressor electrical wiring is plugged in, install battery, turn suspension switch to ON, turn ignition switch to the ON position, close all door and the compressor should come on and completely lower the whole truck. Once the truck is completely down, turn the ignition OFF, remove battery and connect both air lines. Install battery ensure electrical wiring is plugged in, turn ignition switch to ON, the compressor should come on and raise the vehicle to the correct ride height.
