Cadillac Repair: 97 cadillac deville, cadillac deville, vacuum pump

Question
Replaced ac compressor.  Now I get service ac in dash.  How do I override or start compressor?

Answer
After you replaced the compressor did you use a vacuum pump to remove all the atmospheric air from the system BEFORE putting the required amount of freon in the system ?. You will need, If necessary, Electrical schematics, Test procedures 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.
