Re: 96 Cadillac Deville warning lights
Your car uses electronic controls for the engine, transmission, instrument cluster and other functions. In particular, it uses the OBDII system.
See here for more info: http://en.wikipedia.org/wiki/OBDII The electronics have a limited ability to diagnose and report on problems they find in the car. The lights you see are telling you that the electronics have found some problems and you or your mechanic need to fix them. The first step is to 'scan' the electronics to find the codes. On your car, with the ignition 'on', push the 'Off' and the 'warmer' (red) button on the dashboard's climate control section. Now, I think your car has a digital readout on the dashboard. The codes should appear here. You can write them down on a piece of paper for future reference. More information here: http://answers.yahoo.com/question/in...2195649AAKfgid Usually the codes require some interpretation in order to understand what needs repair. This site can give you more info or you can list the codes in this forum and we will try to help. http://www.obd-codes.com/
