1992 Cadillac Deville Electronic Level control system problem

Hello My 92 Devilles rear struts wont stayed aired up,the compressor comes on but only sometimes and only for about 3-5 minutes,sometimes when I look at my car it is sitting level " above the top of the tire",sometimes its "sagging" almost to the rims,it also bottoms out if they are sagged down, the only weight I have back there is my 3 kids "young"and some groceries, usually. Could this be a leak,needs new air struts,or both,also can you tell me where the fuse/relay and the air compressor would be???

    Yes it does come on,but only every ounce in a while.And only for a few minutes.

    Where would I find the load level sensor? And how would I test for leaks?

    Ok I will go check the module is that the relay? If so do you know where it is located? If it is not that I will go ahead and replace the air bag struts. And post back to let ya know if it worked.

    Thank you.

    Ok well I suppose its gotta be the air bag springs. if it was a leak in the hoses would the compressor come on and stay running all the time?

    Thank you.

It sounds to me like you have a hole or cracks in your airbag. The dealership typically diagnoses it as the compressor but that is only to keep you coming back and wasting more money on something that will never truly be fixed. The airbag is the problem now but the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag will kill 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. This is a PERMANENT fix. I added the link below so you can check it out.

I hope I was of some help

Good Luck!!!

The most likely cause is an air leak, the second is the the load level sensor, next the pump motor or motor relay, does the pump run and try and raise the suspension?

    The load level sensor is attached to the driver side rear suspension I think, it is on the rear, that is for sure, has a lever that moves up and down to measure the ride height, then it sends a signal to the module for the suspension control to either turn on or bleed air. Sounds like you have a leaking air bag spring.

    If the pump runs then the relay and module are likely ok

My check your air suspension warning light came on. I checked the book that came with the car and it said, it could be in the electic part of it. So my question to u is what can the electric part be?


It's mostly electronic , There is a control module ,sensor's at the corners ,wheels , an electric compressor to pump air to raise the vehicle .
You don't say what make , model an year vehicle but there all pretty much the same . This is for a Cadillac Deville
The electronic suspension control (ESC) system consists of the following components:
?€¢
Electronic suspension control (ESC) module (3)


?€¢
Four dampers contained in the 2 front struts (5 and 6) and the 2 rear shock absorbers (1 and 9)


?€¢
Four positions sensors (2, 4, 7, and 8)


?€¢
ALC air compressor module (10)


?€¢
Damper relay (not shown)


?€¢
ELC relay (not shown)

The ESC system with rear automatic level control (ALC) controls damping forces in the front struts and rear shock absorbers in response to various road and driving conditions. The rear ALC portion of the system maintains a proper vehicle trim height under various vehicle load conditions. For more information on the ALC, refer to Automatic Level Control Description and Operation in Automatic Level Control.
The ESC module receives the following inputs: wheel-to-body position, vehicle speed, and lift/dive. The ESC module evaluates these inputs and controls actuators in each of the dampers independently to provide varied levels of suspension control.
Your best bet is take it to the dealer !

92 cadillac deville no heat or air blowing at all


Devilles use a controller instead of a basic blower resistor.
Someone would need to check the blower motor for power and ground, then check the controller mounted in the HVAC box on the firewall.
You may need a shop manual to get the wiring diagrams needed to troubleshoot the system.

The rear of the car sets higher than the front, suspension is stiff in the back to. Is there a suspension control system that is not working


There's a level sensor in the back of most cars that have air ride suspension such as Cadillac Devilles.

If there is plenty of pressure, it's probably not a leaky air shock aborber nor is it a bad air pump under the hood.

Electronic level control not working right in a 1999 cadillace deville, what can i do to fix it?


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 have a 1996 Cadillac Sedan DeVille. This spring...


If the a/c does not engage as a result of the electronic control system in your 1996 Cadillac, the climate control system may need to be replaced.

However, if the problem is being caused by low charge of R134a in the system, have the system charged before changing that electronic part.

I have never seen a Cadillac Climate Control System do this, which leads me to believe that it may be more electronic than refrigerant pressure related.

If the refrigerant pressure was low in the system, the climate control system should still stay on 'auto' mode, I think, and simply blow warm air.
