To remove the struts on a Mystique, Loosen the lug nuts on both front tires. With a hydraulic jack, raise the vehicle on one side, then place a jack stand under the vehicle and adjust it to the proper height for the vehicle to rest on. Repeat this step for the opposite side.--------------------------------------------------------------------------------

Have a similar problem... My 2003 Lincoln Navigator was manufactured May 22, 2003 so it's the late model that came with the Intec 5.4 Liter DOHC V-8 (not the Triton engine).

I replaced the two front ride height sensors (one for each air strut) and replaced the one rear ride height sensor that controls the ride height for BOTH rear air struts. (Yours may have one ride height sensor for each of the rear air struts.) That solved the problem for a few months during the warm months, until the weather started cooling off. Then back to the same issue.

The front passenger air strut started releasing air from the solenoid (air block) making a "hissing sound." Replaced BOTH front air strut solenoids (connected at the top of each air strut). That also resolved the problem for a few days. After going all around the world, I discovered it's the Air Ride Control Module (ASM) that was the problem all along.

It could be the suspension if you have the semi airmatic suspension equipped on the vehicle. It will level itself out to a certain height after the vehicle is turned off. Most of the time the wagons are equipped with a self leveling suspension at least for the rear. The pump and the filter where the air would release is in the right front underneath the headlight if i remember correctly

The suspension has a leak somewhere and/or the airmatic compressor has stopped working properly. You need either the Mercedes star diagnosis system (SDS) in order to access the suspension control module to tell it to raise the vehilce or you can try to trick it by jacking up the car so it thinks it's sitting at the correct ride height. But as long as the display reads a warning it won''t allow the airmatic compressor to run.

Air leak from lines , struts or components?

your shocks are leaking or a leak in the lines or pump it has a rolling diaphram when you hit a speed they lower and raise on speed

if you cant find the leak you can pump the strut with a compressor if it has a leak replace it if they are expensive and you wish a cheeper fix you can cap off the front lines or rear or replace all of them with regular coils and struts if off a used car the struts may be bad the spring is heavy and the strut needs to be removed and checked if its bad get new ones they are not cheep but the air ride struts new are a grand or better well they use to be a used one was a few hundred i replaced them with springs on a gl-10 years ago and the light may blink remove the bulb or a wire under the drivers side seat not sure on that year

Sounds like you may have a leak in the airmatic suspension struts on the rear. These govern the height of the car in different modes. Not an immediate problem unless you are loosing a visible amount of fluid but it will only get worse.

To check if you have airmatic you will have buttons just behind the gear lever which can be used to put the car in to a stiffer, lower mode or to raise it for rough ground

no you do not! this is a congame! unless your struts do not return to full ride height in one two two bounces when you push on the front of your hood you do not need to replace them. they wear out just like shocks

There is a problem with the air-ride system, or the active body control system.

Is the car sitting lower than normal?
