Cadillac Repair: 2000 Cadillac deVille electronic level control, electrical schematics, electronic level

Question
My rear electronic level control stopped working. It worked just fine until a couple of weeks ago. It was rather noisy but worked. I checked the connections and replaced the relay and still nothing.

Thanks for your time, Steve

Answer
Your problem is most likely the PUMP or the HEIGHT SENSOR. You will need, If necessary, Electrical schematics and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
