There are scanners which have a function to diagnose the air-ride system. It will take a more expensive scanner that has this function to do the job. Since some electrical shops charge by the hour, a scanner pin pointing the problem in minutes will save you money. Replacing the correct part will also save money instead of financing trial and error parts buying.
Some of the system is activated by the opening and closing of your doors. Parking slope also activates the system to level. The master dump valve for maintaining pressure is located around the bottom front of the front wheel well.
While the air system is expensive, overall replacing one component is a lesser expense. If you did not have air ride the vehicle would handle differently. You get what you pay for and maintenance is a cost other people do not pay with plain steel springs.
Take your vehicle to someone who has a compatible scanner to read your air ride.

I would recommend going to strutmasters.com 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. Airbags and compressors are constantly having to be replaced. Also something alot of people don't know is that theses air suspensions are not meant to be in temperatures above 90 Degrees or below 40 Degrees. That is most of the world. The temperature will cause you to replace alot of bags. and typically when your replacing a bag you are going to have to replace the compressor to because the bag had a hole or small crack in it causing the compressor to over work and it will die. I posted the link below so you can take a look http://www.strutmasters.com/lincoln-suspension-parts-s/1.htm I hope I was of some help Good Luck!!!

Could very well be faulty relay, bad fusible link, or a fuse in general. You can trace the wiring or view a free repair manual at autozone.com to trace wires to find faulty device. You can use an ohmmeter or multi-tester to test relays and fuses.
