Air compressor bad?

Hi. I have an issue with mt TC. After the car has been off for a while,i hear the air compressor for the air suspension turning on for a few seconds. It sounds like its pumping the air in the suspension. Is this normal?? I thought that happens when you first turn on the car.

Ok this what i found out.On the older Lincoln systems, the control module monitors ride height for up to an hour after the ignition is turned off, venting pressure as needed to maintain correct ride height. During this time it will lower, but not raise the vehicle. At the end of the hour, the compressor will kick in for up to 30 seconds to add air if ride height is low. After that, it shuts down and makes no further corrections until the ignition is turned back on. When the ignition is turned on, the system will raise ride height if necessary, but not lower it. After 45 seconds, it will then make lowering corrections as needed, but only if all the doors are closed. It will not make any corrections if the brake pedal is depressed. Once the system is in its "driving" mode, it averages input from the height sensors before making any adjustments in attitude. This prevents the suspension from trying to compensate for every bump in the road. Only when a continuous high or low indication is present for more than 45 seconds will it react and make a change. If a change in ride height isn't accomplished within three minutes after the need is indicated, the system warning lamp comes on and stays on as long as the ignition remains on. When the key is turned off, the warning lamp will go out and remain out unless the same problem is indicated the next time the key is on.:smooch: :lol: Yes, i am happy this is perfectly normal!

my 95 town car is the same exact way. i too thought that the things u were noticing with the air compressor were a problem. turns out its all normal.

Man am I glad I have 79s. So much junk to go wrong on these newer cars. The more "stuff" they put in, the more "stuff" can break. Don't think I'd ever own another Lincoln after 79. After looking under the hood of my 66, it is hard to believe I bought the 79s with all the stuff under their hood!!
