Lincoln air suspension

Those Lincolns are notorious for that,I'd just get a set of coil springs out of a Crown Victoria cop car(junk yard)and swap them out.Done it many times,you can do it in about an hour,and they'll never leak down again.By the way,there's some O-rings in that system.Make some soapy water and spray every connection,just maybe you'll get lucky.

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.

I have serviced these in the past and it will probably be a combination of things. I just a few weeks ago fixed a 1999 with the same problems. Generally from past repairs, the electric pump has been working overtime to compensate for leaking rear air shocks. The best solution is to replace them both, not a cheap repair, the pump around 275.00 and each shock arount 275.00.
Just with every thing over time things fail, the rear shocks develop leaks over time/weather cracks, they are easy to check, soapy water will identify this as the problem. If you can get under it enough to spray around the bottom of the shocks when they are inflated. These systems are computer controlled and if you have the proper scanner you can check the system out for eletrical problems easily. My past experiences with these suspensions as almost always the shocks and pump.

Leveling sensors froze up ? Have you been through snow & slush?
Can the vehicle be stored in heated garage for a night?
