AIR SUSPENSION LIGHT CAME ON. REALIZED I HAD A BLOWN FUSE UNDER THE HOOD. CHANGED OUT THE 30A FUSE. AIR SUSPENSION LIGHT WENT OFF BUT NOW THE WHOLE REAR END OF THE CAR IS SITTING ON THE GROUND.AIR SUSPENSION IS ACTIVE. SWITCH IS ON.WHEN AIR SUSPENSION LIGHT CAME ON THE BACK END OF THE CAR WAS NORMAL.IT WAS AFTER I CHANGED THE FUSE AND THE LIGHT WENT OFF THAT THE REAR AIR SUSPENSION APPARENTLY WENT OUT AND LOWERED THE CAR IN THE REAR.WHAT COULD IT BE?
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.
Went through the same with my 99 town car and it turned out to be the bottom of the compressor had rotted out. Ditched the air suspension and replaced with coil springs and regular shocks for under 200 dollars Canadian, labour included, and the car handles just as good if not better. The only issue is the air suspension light staying on but any garage with a proper diagnostic device can switch it off easily.
Have you checked the level switches on each tire?
Sometimes they get stuck up or down or fail.1st thing to check

How can I locate the air suspension pump on a 2000 lincon cartier
This is a very common (and expensive problem) air systems can be difficult for even the most seasoned mechanic to properly and completely diagnose. Air bags are prone to dry rot, compressors get overworked, dryer become saturated.... these systems are WAY overengineered and NOTRIOUS for their problems. They work like a house of cards. Once one component has a problem, they over stress other components in the vehicle causing those to fail as well. Have you looked into conversion kits at all? http://www.strutmasters.com offers custom built conversion kits that could convert you from an active system to a passive system. The ride quality is VERY similar and you will find that it is actually a little more responsive when it comes to handling and cornering. There are a couple of companies out there offering conversion kits but Strutmasters uses powder coated (for extra protection from the elements.. steel is easily corrodable without it) American Steel coil springs. The steel is much stronger than the steel their competitors get from China...They also never re-heat or re-shape the coil springs to fit their needs (a very common practice with cheaper conversions).. reheating steel compromises its strength and integrity. http://www.strutmasters.com/lincoln-town-car-suspension-s/37.htm there is a link for you to take a look at it. I hope this helps save you some time and frustration in the long run!!!
Its under air filter on passemger side and then under another piece of plastic that deflects water away from it. Pull up air filter box and then the plastic piece thats rounded under that and you will see compressor clearly and have clean access
I'm not a mechanic but I have replaced a few of these air Lincoln Town Car suspensions with springs. It's an easy job for DYI types. Not expensive and you can find the springs easily online. I did a 94 and a 98 newer type. They use the same springs. The only thing difficult was the small hole to get at the top bold on the shocks on the 98. I replaced the shocks same afternoon. You have to rip open the old shock to get a grip on it and stop it from spinning. You-tube has a good example of trick to change the shock. Don't suffer with air, the springs ride nice and are good for towing. True the back end of the car sits alittle high after but looks nice.
There are two fuse boxes. A baqttery junction box under the hood on the drivers side and one inside on drivers side. Good luck.

THANK YOU FOR YOUR HELP. IT IS MOST APPRECIATED
I replaced the air bags and cylanoids. Still lost air. Mechanic disconnected the electrical system controlling the air pump and the air bags stay inflated. What is the solution? Gregg Mullins, [email protected]
My 2005 Pontiac Bonneville rear suspension air compressor keeps running and my back end looks jacked up
