Inspect the horn: Check the horn itself to make sure it's not damaged or stuck in the "on" position. Listen for any unusual sounds or vibrations coming from the horn.
Check the horn relay: Locate the horn relay in your Olds Alero's fuse box. It's usually a small, rectangular device marked "horn" or "HORN." Check if the relay is properly seated in its socket and that the connections are secure.
Test the horn fuse: Locate the horn fuse in the fuse box. It's usually labeled "horn" or "HORN." Check if the fuse is blown by visually inspecting the filament inside the fuse. If the filament is broken, replace the fuse with one of the same amperage rating.
Check the horn switch: The horn switch is located on your steering wheel. Press the horn switch and see if the horn honks. If it doesn't, there may be an issue with the switch, its wiring, or the horn relay.
Check the wiring: Inspect the wiring harness that connects the horn, horn switch, horn relay, and fuse box. Look for any loose connections, broken wires, or damaged insulation. Repair any faulty wiring as necessary.
If you've checked all of these components and the horn is still honking nonstop, you may need to seek professional help from an auto mechanic or electrician to further diagnose and fix the issue.
