I am working on my grandfathers 1993 DeVille and this one part keeps turning on every so often when the car is off and has been for quite some time. It will run for a few seconds and then turn off. It will happen 10 seconds after you turn off the car or sometimes it will be 10 hours, totally random. Trouble is his batery keeps getting charged down and I dont know what this part is. Here are some pictures of the part. I hope someone knows what this thing is. Also there is no part number or anything stamped, written, or stickered to the part. Thanks for the help if you can.

Again thanks in advance if you know what this part is.

That is the ELC (electronic level control) compressor. It is turning on because there is an air leak somewhere at the rear shock or the air line and the shocks leak down. Then the level sensor detects that the rear end is low and pumps it back up again and the cycle continues.

Thank you Ranger. Many of the posts that Ihave read say that your answers and advice should be take as fact, so I am glad to get a reply from you.

Well, not always. I have been wrong before, but we won't tell my wife or daughters now will we. My daughters grew up thinking that "I was only wrong once. That's when I thought I was wrong".

Spray all the air line connections with soapy water and watch for bubbles to aid in finding the leak.

FSM is the only place I can think of. My guess is that the line runs along the drivers side to the rear, being that the compressor is on that side.
