Instead of disabling the airbag, follow these steps:
1. Disconnect the battery: This is the crucial first step to prevent accidental airbag deployment. Disconnect both negative and positive terminals. Wait for at least 60 seconds to allow the system to fully discharge.
2. Consult a repair manual: A factory service manual for your specific 1995 Chevy Suburban is essential. It will provide detailed instructions and diagrams on how to safely remove the steering wheel and airbag without risking deployment. These manuals often show the specific procedures and precautions necessary for your vehicle's airbag system. You can find these manuals online through various automotive parts retailers or online libraries.
3. Professional assistance: Consider taking your Suburban to a qualified mechanic. Airbag systems are complex and potentially dangerous, and a professional will have the proper tools and knowledge to safely replace the horn switch. The cost of professional repair is far less than the potential cost of injury or damage from an accidental deployment.
Attempting to disable or work on an airbag system without the proper knowledge and tools is extremely risky. The potential consequences far outweigh any savings from DIY repair. Your safety should be your priority.
