Is the compressor on and the car leveling? If so, I would suspect a leak in one on the lines or the shock boot.

The car seems to stay in a "lowered" position. How can I tell if the compressor is on? can I replace the compressor and the related assembly? If so, what is the difficulty level for someone who can read and follow instructions very well.

In my experience, I have never seen a compressor go bad. It's always been the shocks leaking for me. I'm not saying they don't go bad but in all the car's I've owned it's always been the shocks that fail.

I think the compressor is under the hood on those, is that correct? Near the brake booster. I would imagine they're pretty easy to change.

Since the green level ride light is on, I would suspect that the compressor is running. I think Codewise is correct in the location and you should be able to hear it running, not to mention being hot to the touch if it is. Replacement should be simple, but if it is running the problem is a leak in the line somewhere. Spray the lines and fittings with soapy water to locate the leak.

You are absolutely correct, the compressor is under the hood near the break booster. I do hear the compressor coming on when I turn the key to the on position. However, I was under the car today and I noticed something pecular. There is some sort of cable that is connected to the compressor that is identical to two cables that i saw under the rear of the car on the driver's side. The funny thing is that they aren't connected to anything. Could this be my problem? Where do the cables go?

Are they cables or air lines? There should be an air line or hose that goes to each rear shock/strut. The compressor pumps up the rear struts to keep the rear level. If a previous owner changed the car over to non-air ride struts they should have disconnected the compressor. If you still have air ride struts and the lines are disconnected the compressor will run continuously and the car will be low in the rear.

Until you get this figured out and corrected, unplug the compressor so it does not run continuously and burn itself out.

Thank for the info. I'm sure that they are some sort of cables in the rear. I bought the car from an older gentleman who was the original owner. I will look to see if the air lines were disconnected, and I will unplug the compressor until I figure out what's going on. Thanks agian to the knowledgable people who replied.

I have the '79 Seville 'Electrical troubleshooting guide' on line. Please check www.cadillacseville.org

I used it to troubleshoot the same system on my '78 Elegante and I came to the conclusion that my sensor (at the rear axle) is broken :crybaby:

Succes:thumbsup:
