If you are not comfortable working with car airbags, take your car to a qualified mechanic. It's simply not worth the risk of injury.
However, if you are determined to proceed (at your own risk), here's a *general* outline of the process. This is NOT a detailed instruction manual and may not be entirely accurate for your specific vehicle. Consult a repair manual specific to your 1995 Buick Roadmaster for precise instructions and safety precautions:
1. Disconnect the Battery: This is the single most crucial step. Disconnect both the negative (-) and positive (+) battery terminals. Wait at least 30 minutes to allow the airbag system to fully discharge.
2. Safety Precautions: Wear safety glasses and gloves. Have a non-conductive work surface. Do not use tools that could short circuit the airbag system.
3. Steering Wheel Removal (Often Required): You likely need to remove the steering wheel to access the horn contact. This usually involves:
* Removing the steering wheel cover.
* Removing the horn contact bolts (These are usually hidden behind the steering wheel).
* Using a steering wheel puller (a specialized tool) to remove the steering wheel. This step is critical to avoid damaging the steering wheel or the airbag.
4. Airbag Module Disconnection: Once the steering wheel is removed (if necessary), you will see the airbag module. There will be connectors attached to the back of the module. These connectors are usually secured with clips or screws. Consult a repair manual to understand how to safely disconnect them. *Do not yank or force them.* Work carefully and deliberately.
5. Horn Repair: Once the airbag module is disconnected, you can access and repair the horn. The horn typically consists of a contact ring and a spring mechanism that makes contact when the steering wheel is pressed. Repairing it might involve cleaning contacts, replacing a faulty wire, or replacing the entire horn itself.
6. Reassembly: After the horn repair, reverse the process to reassemble everything. Make sure all connections are secure before reconnecting the battery.
Again, this is a simplified overview and may not be complete. Obtain a repair manual specific to your 1995 Buick Roadmaster before attempting this repair. The repair manual will have diagrams and detailed instructions that are crucial for your safety and success. Improper handling of the airbag system can lead to severe injury or death. If you're uncertain about any step, consult a professional mechanic.
