Question about 1992 Cadillac Seville
My dash lights are going crazy ( fuel , check engine, check ac , service soon ),i know its a computer problem but there are 4 of them,which one is causing this and where is it located and does it have a name?
The service engine soon light indicates you have a problem with the engine management system.The only way to get it to stay off is to lacate and repair whatever is not working correctly. Requires very specialized equipment. Take it to your mechanic.

On a lot of cars the light is reset when you get an oil change, air filter etc. It's overdue for a "look see". You can always go to advance auto and borrow the code reader for free. Plug it in under your dash and will read and reset any codes

This is most likely referring to the steering positioning sensor but to know for sure you will have to have a code reader to get the code and go from there. Sorry, but whiteout a code there is no way to tell you any more.

"Service Engine Soon" message means that the PCM (Powetrain Control Module aka engine computer) has detected a fault in the fuel, ignition, or emission systems. It is the same as a Check Engine light.
This could be something as simple as a loose fuel cap, or it could be a circuit problem with a component like a fuel injector, O2 sensor, temp sensor, emission system component, etc. When this message appears the PCM stores a trouble code that tells the technician what component is acting up.
This code can be read with a scan tool or code reader. Once the code is retrieved, then the tech can follow the diagnostic procedure for that code and troubleshoot it and then repair it. Most shops (and the dealer) have the equipment to do this. Autozone and some auto parts stores also have a scan tool that will connect to your Cadillac and read the code so you would have an idea as to what component is setting the code; most auto parts stores will check this for no charge.
If the vehicle seems to run ok, then I would not worry too much, but still get the code checked as soon as it is convenient. If the vehicle is running bad, then get this checked as soon as you can because continued driving it may cause further damage.
Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer. Thank you for using FixYa.

Whenever this warning or any other stays on in the dash it is indicating that the systems control module has detected a fault, it then disables the system as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)
