Before You Begin:
* Disconnect the battery's negative terminal. This is crucial to prevent accidental shorts and electrical damage.
* Gather your tools: You'll likely need a small flathead screwdriver, a Phillips head screwdriver, possibly a small socket set (depending on the retaining nut), and possibly needle-nose pliers.
* Take pictures: Before you start disassembling anything, take detailed pictures of the steering column and ignition switch area. This will be invaluable when reassembling.
* Consult a repair manual: A shop manual specific to your 1964 Chevy Nova will provide the most accurate and detailed instructions. This is highly recommended.
General Steps (These may vary):
1. Steering Wheel Removal (Possibly): In some cases, you may need to remove the steering wheel to access the ignition switch. This usually involves removing a nut at the center of the steering wheel (after disconnecting the horn wire). Be extremely careful when removing the steering wheel as it can spring back and injure you. A steering wheel puller is recommended.
2. Steering Column Shroud Removal: The ignition switch is typically located behind a shroud or cover on the steering column. Carefully remove this shroud; often, there are screws or clips holding it in place.
3. Wiring Harness Disconnection: Once the shroud is off, you'll see the ignition switch. Before attempting to remove it, carefully disconnect the wiring harness connector(s) from the switch. Note the position of each wire to ensure correct reinstallation. Take photos!
4. Ignition Switch Removal: The ignition switch itself is usually secured with either a nut or retaining clip. This is where the socket set or pliers might come in handy. There might be a small plate or retainer to remove first. Again, take photos at each stage. It might be held in with a retaining clip that needs to be gently pried or slid off.
5. Removal of the Switch Itself: Once the retaining nut or clip is removed, the switch should slide or pull out.
Important Considerations:
* The ignition switch is a precision part. Be gentle to avoid damaging it.
* Properly label all wires before disconnecting them. This will prevent problems during reassembly.
* If you're unsure about any step, consult a professional mechanic. Attempting this without proper knowledge could damage your vehicle's electrical system or steering column.
This process is inherently complex and can vary based on your specific car's configuration. Using a repair manual specific to your 1964 Chevy Nova is strongly advised. Attempting this without the correct information could lead to damage. If you're uncomfortable performing this yourself, a qualified mechanic is the best option.
