    The mechanic replaced the control module as well as the height switch thing by the left rear tire. Compressor will not turn on, airbags will not inflate, and all components check out good for power.

This is a very common problem with all Lincolns. The air ride suspension are marketed as a luxury-comfort item but most do not know that they have a 100% failure rate and are designed to fail as shortly after the warranty expires as possible. The air bags that support the weight of the vehicle are not designed to withstand temperatures below 40 degrees or above 94 degrees and are very prone to dry rot. Once the bags start getting tiny cracks and leaks they start overworking the compressor. (Picture trying to blow up a balloon with holes in it.. you will try for as long as you can but will ultimately have to give up) These air ride systems can be very difficult to accurately diagnose the first time and consequently very expensive. Most people seem to be converting to a passive suspension system these days as the ride quality is too similiar to notice a difference and the reliability is paramount. http://www.strutmasters.com offers a high quality conversion kit that utilizes powder coated American steel coil springs that are actually designed to last the lifetime of the vehicle. http://www.strutmasters.com/lincoln-suspension-parts-s/1.htm there is a direct link to the Lincoln page. I hope this helps save some of you a little bit of grief and a lot of money in the long run!!

Typically with these systems, compressors run fine until a leak is introduced somewhere else in the air ride system. Primarily the air bags (made of a rubber not designed for long term exposure to temperatures below 40 or above 90 degrees) start to dry rot and get tiny cracks and pinholes on the inside fold of the air bag which can make it very hard to properly diagnose. There could be so many problems with this system that it seems like most people are choosing to convert it. http://www.strutmasters.com offers a high quality conversion kit that is DESIGNED to last the LIFETIME of the vehicle and come with a lifetime warranty. Basically you convert to to a passive coil spring system like PLENTY of other cars out there. Manufacturers didn't invent the air ride for safety (air rides actually try to fight natural physics when the car leans naturally through a turn). They invented it as a luxury-comfort item that would fail shortly after the warranty has expired (typically) and force consumers to put more money into the dealer's shops pockets. Free yourself from the air system and never worry about your suspension again

Check or replace the height sensor located in front of the rear axle expensive $180.00 that is what turns on your compressor, compressor around $300.00

SOURCE: air suspension problem compressor does not turn on

Check the induction coil of the rectifier. See if sufficient charge is being developed to start compressor. If this initial surge is being delivered via any capacitor, then have that checked too.Since the compressor is not starting finally check the compressor by giving it power directly from the battery, appropriately stepped down if necessary.........sodeep

Air suspension light comes on after copmpressor stops running


Sounds like you need to check the air-bags for a leak. Unfortunately, the compressor may have wore itself out attempting to continuously provide air to the air-bag and may also need replacing. Just my $0.02 worth.

Air suspension will not deflate


You need to find someone with a scan tool that can access the air suspension and manually cycle the individual springs to restore level. As a word of advise, turn the air suspension switch off, before you hoist the vehicle. This will prevent the compressor from inadvertently filling the air springs.

2002 linncoln towncar where is the air supension compressor relay switch,please.


Air suspension needs compressed air for the control of Air Springs (Air Spring is a cylinder like thing which goes up and down when air is pumped in and out of it). For pumping in and out the air, air compressor needs to be switched ON/OFF. Compressor relay connects and disconnects the compressor motor from the power supply ( battery). ----------------- air ride suspension compressor located under the air filter box . ---------------- the Air compressor clutch relay location
is fitted to the left hand inner wing (when viewed from the the driving seat).
-------------------
the compresser is located on the left hand side of the car under the hood.
once you open the hood remove the air cleaner housing and windshield washer resivor.
there is a panel that you lift up under both of thoese that is where the compresser is located
-------------
  1. The air suspension uses a small, separate air compressor under the driver's side left fenderwell, with air lines running to the air bags. On the top of each air bag is a electrical valve. This is a relief valve that allows air to be exhausted when activated, and which senses the amount of air pressure within the air bag to keep both sides equal. These valves are operated via a leveling sensor that is attached to the body of the car and to the rear axle by a movable arm. When the rear of the car drops due to increased load, the arm is pushed up. When the arm is pushed up, it turns on the air compressor and fills the air bags to level the car. When the load is removed and the arm moves down, indicating that the back of the car has risen, the sensor opens the valve on the air bags and allows air to escape, lowering the car.
  2. If the back of the car is low, indicating that the air suspension is not working, and the air suspension light is on, check the fuse first. If the fuse is all right, check the air suspension switch in the trunk and make sure it is on. This switch is used when the car is in for service. Always turn off the switch before lifting the car, because the sensor will think the car is rising and keep the air bag valves open, ruining the rear air suspension.
  3. Turn the ignition key with the engine off. Listen for the compressor to come on while pushing down on the rear bumper. If it does not come on, test the switch terminals for power, using a circuit tester. If one terminal has power and the other does not, replace the switch. If there is power, turn the switch to the off position, raise the vehicle and place it on jack stands in the rear. Inspect the leveling switch on the axle, making sure it is not bent and is connected. Use an ohmmeter for this test. Pull the electrical connector off the switch. Loosen the arm of the switch from the axle. Test the switch with the ohmmeter by checking across both terminals while slowly moving the arm. There should be no continuity with the arm down. As the arm is raised, there should be continuity. If not, replace the switch. If there was continuity, connect the arm and the electrical connector.
  4. Put a floor jack under the axle and raise the axle to the point where it is just beginning to lift the car off the jack stand. Turn on the ignition. Turn the air suspension switch to the "on" position. Use the circuit tester to check for power at the leveling switch. If there is power, turn the air suspension switch to "off" and lower the car. Access the air compressor in the front, under the hood, and check the electrical connector for power. If there is power, check for a good ground. If both are good, replace the compressor. If the compressor works and the car does not rise in the back, replace the air bags.

1998 crown vic air suspension compressor does not pump.


Sounds like the problem is in the air bag suspension, not the compressor. The air bags shouldn't be losing air when the car sits. The compressor adjusts the suspension level according to the load. The air bags have a valve similar to a blow up raft that allows air to pass through both ways. If when the car is running the compressor is constantly running and not turning off, the issue is within the air bags and/or the air line.

Im going to live it parked for 3 months


Hi, 3 months is not that long for a car to sit. But yes, turn the air suspension switch located in the trunk to "off", disconnect the + positive from the battery post under the hood, and last fill the gas tank (full) to prevent inner gas-tank corrosion. When you return, connect the + positive to the battery, start the car, then turn the air suspension switch to "on". Don't be surprised if the air bags in the suspension lose some air while gone, the bags are known to leak.
