To troubleshoot a horn that's not working, you should:
1. Check the fuse: Consult your owner's manual to find the horn fuse and check if it's blown.
2. Inspect the horn relay (if applicable): Some models use a relay; check its connection and condition. The relay might be located in a fuse box or under the hood.
3. Test the horn switch: See if the steering wheel horn button is making contact.
4. Check the horn wiring: Look for any loose connections or damaged wiring leading to the horn(s) themselves. This often involves looking under the steering column and potentially under the hood.
5. Test the horns themselves: If you can locate the horn(s) (often mounted on the radiator support or bumper), you can test them directly with a battery and jumper wires (be very careful!).
Without knowing the specific 1984 Chevy model (e.g., Camaro, Silverado, Celebrity, etc.), it's impossible to give more precise instructions. Your best bet is to consult a repair manual specific to your 1984 Chevy model. You can find these online (often as PDFs) or at auto parts stores.
