my shop told me that my compressor went out - later I found out that the air bag had tiny holes ffrom dry rot on the INSIDE of the bag which was what was killing my compressor! I ended up converting to a pssive system. I got it from StrutMasters.com mainly because it came with a lifetime warranty. I was pleasantly surprised at the ride quality and would never go back to air bags and compressors again.
A person can reset the air ride suspension on a Cadillac Deville by disconnecting the compressor wiring harness from the compressor itself. This is accomplished by putting the vehicle on ramps.
Air ride compressor, air suspension compressor, and air pump are the names used for the same device. They are used to pump up the air suspension.
the compressor should be under the hood on the front passenger side, it should be.
Air suspension needs compressed air for the control of Air Springs (Air Spring is a cylinder like thing which goes up and down when air is pumped in and out of it). For pumping in and out the air, air compressor needs to be switched ON/OFF. Compressor relay connects and disconnects the compressor motor from the power supply ( battery).
No it should not. They have a ride height switch, which cycles the compressor. You probably have an air leak in the system.
how to replace air suspension compressor
I just had similar problem with 2000 expedition. It was the bracket not the compressor. but if you don't fix bracket soon compressor will go bad too.
you just do! you have conventional suspension, there is no need for one...
Above the right rear axle. you can see it if you lay on the ground and look above the axle from the rear of the car
air suspension switch in trunk. compressor under hood
You should check out the Cadillac Deville suspension conversion kits at strutmasters.com If you can do brakes you can install their conversion kits yourself. http://www.strutmasters.com/cadillac-deville-suspension-s/42.htm
Check wiring again. Check for bad ground. Recheck all connections.
