Electronic Level Ride System May Fail on Cadillac DeVille

Problem Description and Possible Solution

The electronic level ride system may not work properly; this may result in the rear of the vehicle riding too high or too low. Our technicians tell us that a height sensor or exhaust valve failure are common issues with this system. Proper diagnoses will be necessary to confirm the exact fault.

My car is riding to low. I dont have the money for repairs.But,i can do it my self,if someone tell me/
Level ride not working car setting too low
when i drive down the road the rearend sways side to side. i haven't tried anything yet. i am looking for the solution.
My car is not sitting at the proper height,Its saging and I have to watch how I back out of driveways.Its not sagging to the ground.
Compressor does not run. Checked relay/ fuses. Ok.
rear electronic air schocks rear of car setting high one side higher 2004 caddie deville dts how do i disable to get rear of car down
rear air shocks leaked. WAY expensive to replace with OEM, so installed spring shocks and bypass resistors.
Worked great!
The air ride suspension motor works but the car still sits low
I have a 2005 Cadillac dts that the rear air ride compressor is not working, if I banged on the old one it would work sometimes. Bought a new compressor and installed and the compressor still doesn't work.
Vehicle seldom used to transport passengers. First noticed when two persons, with baggage, was being transported to Airport, noticed vehicle ride was exceptionally rough and very low in the rear, barely clearing the ground.
It continued to sit low but ride improved when passengers were dropped. A check with the Cadillac Dealer quoted an outrageous price to diagnose the problem, therefore, no repair or diagnosis were ever done to date. Vehicle has only 72,000 miles.
The front has no air and bounces down the road. The back used to move up and down. It stays down all the time now.
The rear of this car,seems to sit a little higher
my 1990 Cadillac Deville Coupe's rear end drops down after about 10 minutes of driving. I have 20 inch rims on it so that is a problem because the tires rub. i put on new shocks thinking that was the problem, for the most part its fixed but say when i drive up a steep hill and the back end drops below a certian point the back end wont level back up to where it should be
With any weight in the trunk the bottom sags and rides low.
The rear end is sitting too high
rear of car rides too low; mud flaps drag
Just bought the car and it says service ride system my dad said I need to do the shock conversion beclouded my air bags aren't working
rear end too low!
Setting a little low and more rough ride then it should be
Back is low
