Automatic Level Control

How can I tell if my automatic level control works

Load up the trunk, put the key into the on position and see if the ELC sensor fires up the compressor and fills your rear shocks with air.

If it doesnt you may have a decfectve compressor or sensor itself

Thanks for the info Rorastar96

Where is the level sensor located? and where is the compressor?

located under the vehicle by the rear passenger door

I have not seen a lot of bad sensors ussualy there is a relay that runs the compressor. That is some times hard to find. Seeing how the car is not that old I would bet on the relay

The compressor on my '95's automatic level control seems to be working fine, however, it doesn't seem to release any air. As a result, the rear of the car has the stance of an early 70s Nova with too much air in the air shocks (no offense to my fellow Nova owners out there).

Any ideas?

Much thanks!

Hi,
Are both shocks extended or only one side, this happened to mine on one side and found out one had ceased up, they were 3 months old and were AC delco which are known to have an issue is what my mechanic said. Also check for visible leaks (grease film).

Both sides are equally high - thanks

I would load the trunk up and with a flashlight see if you can see the shocks extend (fill or release air), I tried this and actually saw the air fill up the shocks so I now know things work.

The electronic leveling control in my 1995 Aurora quit working about a year after I obtained the car.

I researched the matter on this forum. Here's what I learned and then here's what I did.

The system is comprised of a sensor rod, a relay, a small compressor, hose lines to the rear shocks and air over oil shocks. All original equipment manufacturer replacement parts are extremely expensive. The forum provided alternate parts and sources for much more reasonalbe prices. Replacement Monroe shocks, MA 822, are available from rockauto.com and the compressor is available from SunCore Industries in Florida at 1-800-260-5175.

The rear of the car is actually supported by coil springs and since my wife doesn't ever haul heavy loads, I did nothing and the car is fine. My suggestion, if your shocks are worn out, is to replace the shocks, charge them with enough air for a good ride and forget about the compressor, the relay and all the other components.
