Question about 1994 Pontiac Bonneville
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.
