You have to retreive the trouble code stored in the computer and then you will know which area you are having a problem in whether it be fuel,ignition,emission ect.
You will need a code reader or a scan tool to do this or go to your local autoparts store like advance auto or autozone and they will retreive them for you.

SOURCE: 94 pontiac bonneville horn does not work. i have
Ok , try this. have an other person push the horn button while you check for voltage at the horn wire. red wire from meter to horn wire and black to ground on car. should get 12 volts, or you can also use a test light. if it light up the circuit is good, or if you read 12 v on meter. replace horn. if not then find horn relay and replace it. sorry i'm not sure where that is located. might have to follow wire from horn back to it . possible under hood on the firewall. if that is not it then the only thing left is the switch in the steering wheel is not making contact. that is all to the horn circuit. hope this helps.

How would I go about getting the trouble codes from the computer?
Autozone doesn't do codes anymore. I know that my car is OBD1, but it has a ODB2 connector.

You will have to buy a code reader because you need to find out what code is stored in the computer to see where to start at.
