Here's a general outline of the process. This is not a comprehensive guide and you should consult a repair manual specific to your 1980 Chevrolet Impala before attempting this. Repair manuals are available online and at auto parts stores.
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Remove the Steering Wheel: This usually involves:
* Finding the steering wheel retaining nut: This is usually located in the center of the steering wheel, behind a decorative cap or cover.
* Using the correct size socket and wrench: This nut is often very tight. You may need a steering wheel puller to remove the wheel safely after loosening the nut. Failing to use a puller can damage the steering column.
* Marking the steering wheel's position: Before removing the wheel, mark its position relative to the steering column so you can reinstall it correctly. This ensures proper alignment.
3. Access the Turn Signal Switch: Once the steering wheel is removed, the turn signal switch should be more accessible. It's usually located behind the steering wheel, attached to the steering column. You'll likely need to remove some other components to get to it, such as the steering column shroud or other plastic covers.
4. Disconnect the Electrical Connectors: Carefully disconnect the electrical connectors from the turn signal switch. Take pictures or make notes to remember how they connect.
5. Remove the Turn Signal Switch: The switch itself is usually held in place by screws or clips. Remove these fasteners to remove the switch.
6. Installation: The installation process is the reverse of removal. Make sure everything is properly connected and aligned before reinstalling the steering wheel.
Important Considerations:
* Safety First: Work in a well-lit and ventilated area. Wear safety glasses to protect your eyes.
* Repair Manual: A repair manual specific to your year and model Impala is highly recommended. It will provide detailed instructions and diagrams.
* Tools: You'll need the proper tools, including sockets, wrenches, screwdrivers, and possibly a steering wheel puller.
* Expertise: If you're not comfortable working on your car's steering system, it's best to take it to a qualified mechanic. Incorrectly reinstalling the steering wheel can be dangerous.
This is a complex job. If you're unsure about any step, seeking professional help is strongly advised. Improper repair can lead to serious safety hazards.
