What is the first thing to check if the horn is not working on Oldsmobile Cutlass?

If the horn is not working, the first thing to check is the fuse. Look at the fuse box under the dashboard to identify a blown fuse. If the fuse is fine, disconnect the electrical lead at the horn and use a jumper wire to connect a 12-volt source to the wiring terminal on the horn. If the horn still doesn't blow, the problem may be with the grounding of the horn or the horn itself. If the horn does sound, then there is a failure in the circuit before the horn. This could be due to a faulty horn relay, bent metal contacts on the horn actuator, or loose/broken wires in the system. The horn relay is usually located under the dashboard near the fuse box. Be cautious when checking or replacing the horn relay as the threaded stud is always hot and shorting it to ground could damage a fusible link, disabling the vehicle until it is replaced.
