check the small short steel rod that runs from the rear axle to a small lever its almost in the middle of the axle it could be broken or the plastic end on it is bad. it acts as a switch, if it is bad the compressor will not shut off and the shocks will keep filling. when weight is put on the car it turns on
It could have load leveling shocks in the rear.
You could do that. The air shocks would have to be manually inflated. You may run into a competition between the manually leveling system and the automatic levilng system.
No there is not. The Monroe 818 air shocks are the closest that may work.
A system using an air pump and air shocks or air ride to keep the vehicle level no matter the load placed on the vehicle.
It is the automatic air leveling system. If it runs constantly you have a blown rear shock.
Does the "Service Stability System" message come up? If so, you probably have a leak in one of the shocks. Warning, the 99 Seville STS has electronically controlled suspension and leveling, the rear shocks and front struts are very expensive to replace.
Yes, Monroe has great adjustable Air Shock applications for all 89-98 Mazda MPVs.
There is no air valve for the rear air suspension as it is controlled by an auto-leveling system unless of course you change to manual fill air shocks then it could be anywhere.
De-leveling the System - 2012 was released on: USA: November 2012
You can repair this system or what I suggest is you convert it to a system with springs and shocks. The link on the left below will sell you repair parts or a conversion kit. Go with the conversion and rid yourself of the problems associated with air ride.
An automatic leveling system is a suspension system which automatically adjusts front and rear ride heights to compensate for changes in axle load.
A headlight leveling system adjusts the vertical aim of the headlights based on the position of the rear suspension. As you load the trunk of a car, bed of a truck, etc. the suspension is compressed to allow the vehicle to ride smoothly. This causes traditional headlights to aim higher. A headlight leveling system lowers the headlight beam to compensate for this allowing the driver to see the road clearly without blinding oncoming traffic.
