Hi, My 91 TC does the same thing, I had to replace the compressor and dryer once, but I believe that it has something to do with the relay in the fuse box by the battery, it's the big square looking gizmo, use the label under the lid for the correct relay, I replaced one, and it seemed to help, but my light still comes on. I have found a aftermarket suspension system for these Town Cars. It is a set of heavy duty replacement springs, which replace the bags. I intend to buy them, they are under $200.00 not counting installation. Many reviews on these parts say the can barely tell the difference, and it eliminates the pump system completely, just how, I'm not sure. I have a friend with limos having same probs, says he will replace bags with springs for me as soon as I get $$$ for parts! I don't know if this will help, but good luck! Michael

You should check the air suspension switch, located on the passenger's side of the trunk. If the switch is off, the light will come on, also check the air suspension fuse. If both of these are OK, then the pump could possibly be going out.

If you fix the problem with your air suspension

I have a 1998 ford grand Marquis- and the problem is the air suspension light stays on- how to fix this problem

A malfunction with the air suspension system has been detected

there is an air suspension switch located in the trunk

Yes , there was standard suspension , sport / handling package , heavy duty suspension , and the air suspension

The air condition has nothing to do with the suspension on these vehicles at all. If you are looking for answers to the problems that come along with the Lincoln Navigator air suspension visit Strutmasters.com :)

These cars have air suspension when they are built in the factory. Likely someone has taken the air suspension out, and left the sensors there, causing it to detect a problem. Not a serious thing.

An air suspension is a form of vehicle suspension in which compressed air is used as a spring.

usually a light implies there is a possible problem. also, make sure air bag switch is on.

It's adjusting to the weight of cargo in your car it should come on when first started if it stays on there is a problem with your rear air suspension =/

Possibly a slow leak in one of your air suspension bags or the hoses that run between the compressor (located way down in your engine compartment, in front of the engine.) OR, if you had the air suspension setup replaced with a more traditional coil spring and shocks suspension, the air suspension light will come on unless you cut the appropriate wire from the control computer (located ahead of the glove box under your dash, reachable if you pull out the glove box.) An alternative that is NOT advised is to remove the fuse that controls the air suspension (assuming you have had coil springs installed.) That is not a good solution as it also disables the variable power steering control, and you end up with maxmum power steering boost at all times, way too little resistance to my liking. Hope that helps. If you HAVE gone over to coil spring suspension and want to know what wire to cut to turn off the air suspension idiot light, email me and I'll try to dig up the info for you.

A possible cause for this is that air suspension pump is continully working due to a leaking air bag

There is an air suspension switch in the trunk on the passenger side. You can turn it of . there is also an air suspension fuse under the hood in the fuse box on the passenger fender well. you can remove that 30 amp fuse also. in the fender well inside the trunk on the passenger side behind the suspension switch. remove the carpet off the side. there is a module with two conections, one grey and one black one. remove the black one. there is one green, with light green wire. cut that wire and reconnect the harness back on. the air suspension light on the dash will go out. this is for 1994 and before Lincoln town cars. on 1995, the module is behind the glove compartment. do the same like on 1994. cut the green wire and the air suspension light will go out. this is the best way to disable the whole system.

That's what warning lights are for to indicate a fault is present

I have reolaced them on 3 town cars every time I but a piece of black friction tape over the light or take top og dash off and remove bulb

there can be many different problems but it could be a bad relay switch to check it get on the floor on the passenger side and check to see if the air suspension relay switch is on, try that for now, usually if someone uses a jack to raise the car and the tires have to come off the ground,they switch it off, so the height sensors don't mess up. but it this causes the check suspension light to come on.

air is somtimes a suspension due to fog and polution air is somtimes a suspension due to fog and polution

A suspension is a mixture of liquids with particles of a solid which may not dissolve in the liquid. Therefore, air would be a suspension.

No, the brkae light does operate with the air but it opporates by a switch that the air itself pushes.

NO , there are standard suspension , standard suspension with off road package , and air suspension equipped 2003 Ford Expeditions

sounds like your solenoids are leaking, usually in your air bag (suspension). or a hose.

On a 1997 Ford Expedition : ( NO ) not on the front suspension It could have the REAR load levelling air suspension

A malfunction with the air suspension system has been detected Most of the time it is because you have to much air in your tires or not enough in your tires, check your recommended tire pressure(psi) with an air gauge when you have the correct pressure turn your truck off and restart it the light will go off.
