I was told compressor could be stuck open allowing the air to purge as quickly as it comes in.

Im tryn to locate the air conpressor so I can rise the shocks.


usually this is located under the hood on fender wells. if nothing else start at the shock and follow air line to the pump. the system is on a self leveling switch located on rear axle which adjust to weight of car turning on the pump for proper ride height and comfort. you should determine why this system is not working. and yes usually there is a valve on the pump which allow you to manually introduce air into the system.

Rear air ride is flat on 95 deville....what do i


the first thing is the fuses. i've seen many of these that the rear air shocks are bad but customer doesnt know and the pump runs until it burns out,after checking the fuses start the car and listen under the hood for the pump to turn on, if pump turns on then check shocks for leaks, also you would have to make sure the pump is producing air as it runs and the last thing is the level sensor located under the rear of car.

Lift sensor for rear of 1988 Deville


To begin with, check the "ride level" fuse and make sure that the ride level compressor does work, and you should be able to hear that the ride level compressor is working when the ride level system is leveling the vehicle.

The ride level system uses an air compressor and either an air type of shocks or a type of air billow to raise and lower the vehicle, there is an adjustment to set the ride height and it is located under the vehicle and there is a control lever or rod that should be connected between the rear axle and a switch that is mounted on the body of the vehicle, and there will be an adjustment slot in the control lever between the switch and the body, and that is how you would adjust the ride level height, but be sure that the vehicle can not drop any further down if someone is under the vehicle trying to adjust the ride height.

However, you might find that the control lever to the ride level has fallen off from the switch on the body or it has come loose from the rear axle, and it is just hanging there not operating the switch on the body that controls the the ride level compressor, or there might be a blown out air shock or billow, or you might find that an air line from the compressor is leaking and the ride level compressor will just run continuously until it blows out the fuse, and if that is the case you might also find out that the air compressor has burned out from running continuously.

I hope that this information will help you to solve your ride level problem.

Why is my cadillac rear so low


You may have a leak in the rear air bags or the compressor for the air bags is not working,listen when you turn on the key to see if you can hear the compressor run ,if you do then likely the bags,if not then likely the compressor.
