I just had my unit converted to coil springs. It a lot cheaper than messing with the air unit. The ride is great and it only cost me $400 parts and labor. Strutmasters has a kit for only $269. Can't beat that!

SOURCE: Check Air Suspension for 2000 Mercury Grand Marquis

It sounds to me like your compressor got killed. What probably happened is that the airbag got a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag killed the compressor. 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. I added the link below so you can check it out.

.y 1996 marquis rear air suspension is not working and it wont lift what should i do


There are few choices. Fix your system or replace the rear air suspension with steel coil springs. Some of the testing scanners can hook up to a diagnostic port and diagnose the air suspension parts. One part can cause the system to shut down. Make sure the on/off switch is set to on. It should be in the trunk next to the fuel pump switch.

Air suspension compressor sounds bad and wont pump up the rear on a 2003 mercury grand marquis


What is odd is the compressor stopping after so short a time. It may be your only problem.

When you have a leak in the system, the compressor keeps running because the sensors do not signal for it to shut off. On your vehicle it is either being told to shut off prematurely or the compressor is triggering a circuit breaker.

There are ride height sensors on the rear. If the vehicle was lifted without turning off the Air ride, the sensors may have been stretched.

You can check for air leaks in the suspension bags, and air lines using a spray bottle of soapy water. There is also a Master dump valve that should be ahead of the Drivers front tire/radiator well area. It is not a concern unless there is no pressure in the system.

Finally, just as the engine can express diagnostic Codes, so can the suspension. You need a better scanner to do this function. It is the quickest way to find the problem.

Please rate my info.

Dash-board Warning Light says "CHECK AIR SUSPENSION". So, I've tried pushing that AIR SUSPENSION SWITCH inside the trunk; but nothing happens = the Rear End of my 1997 Grand Marquis is still "hanging" LOW....


the drier on the pump needs to be replaced every few years, but few people ever do. you could have a leaky bag if the pump runs a lot, or the pump fuse might be blown, or the drier clogged. the switch in the trunk is only for when you raise the car on a lift, leaving the rear axle hanging.

My rear suspension sags after 3 min of operation.The check air suspension light comes on. It goes off if shut down/ start the engine,Some one told me to change the shocks,what about the check light on...


Air suspension bags are probably leaking. air comp shuts off after 3 minutes because its working to hard. since bags are leaking rear than sags. This car has bags instead of shocks in rear. light comes on when comp turns it self off.

When the tester is connected, the engine is started and the HOLD/TEST button is latched down, the air suspension control module will respond sending a code 10 to the Super Star II Tester which represents "Diagnostics mode entered."

Air suspension on my grand marquis comes on with engine off


What is probably going on is the air suspension has a leak so the compressor is breaking down. So it will run at odd times trying to make up for the times it can not run. What you need to do is look for a conversion kit. The conversion will stop all problems that you are having now and you will never have to worry about it again. I would recommend strutmasters.com. They have great prices and there kits are guaranteed to last the life of the car. I posted the link below so you can take a look.
