1. Check the Horn Relay:
* Location: The relay is usually located in the under-hood fuse box or an interior fuse box (check your owner's manual for the precise location). It's often a small, square component with several terminals.
* Testing: You can visually inspect the relay for any obvious damage (burn marks, etc.). You can also try swapping it with a known good relay of the same amperage and type (if you have a spare or can borrow one). If the horn works after the swap, the original relay is faulty.
2. Check the Horn Fuse:
* Location: Again, consult your owner's manual for the location and amperage rating of the horn fuse.
* Testing: Visually inspect the fuse for a broken filament. If it's blown, replace it with a fuse of the same amperage. If the fuse blows immediately after replacement, there's a short circuit somewhere in the system.
3. Check the Horn Button/Steering Wheel Switch:
* Testing: This is trickier. You'll need a multimeter or a test light to check the continuity of the switch when the horn button is pressed. If there's no continuity, the switch is likely faulty and needs replacement. This often requires some disassembly of the steering wheel or steering column. (Proceed with caution and consult a repair manual if attempting this).
4. Check the Horn Wiring:
* Location: Trace the wiring from the horn button, to the relay, and then to the horns themselves. Look for any broken, frayed, or corroded wires.
* Testing: Use a multimeter to check for voltage at various points in the circuit. You should have power at the relay when the horn button is pressed. If not, there's a break in the circuit. Also check for good ground connection at the horn(s).
5. Check the Horns Themselves:
* Location: Typically located behind the front bumper.
* Testing: Disconnect the horns and test them directly with a battery and jumper cables. If they don't sound, they're faulty and need replacement.
Important Considerations:
* Safety First: Disconnect the battery's negative terminal before working on any electrical components.
* Repair Manual: A repair manual specific to your 1996 Oldsmobile Cutlass Ciera will be invaluable for detailed diagrams and procedures.
* Professional Help: If you're not comfortable working with car electrical systems, it's best to take your vehicle to a qualified mechanic.
By systematically checking these components, you should be able to pinpoint the source of your horn problem. Remember to always refer to your owner's manual for specific locations and details.
