Tools You'll Likely Need:
* Socket set: Various sizes, including metric.
* Ratchet and extensions: To reach tight spots.
* Screwdrivers: Phillips and possibly flathead.
* Pliers: Needle-nose pliers may be helpful.
* Wiring diagram: Crucial for reconnecting the wires correctly. Your repair manual should have one.
* New ignition switch: Ensure it's the correct part for your 1995 Cavalier.
* Pen and paper: To label wires before disconnecting them.
* Possibly a security torx bit: Some models use security screws.
General Steps (Consult your repair manual for precise details and diagrams):
1. Disconnect the battery: This is paramount to prevent electrical shocks and short circuits. Disconnect the negative (-) terminal first.
2. Remove the steering column shroud: This usually involves removing screws and possibly some plastic clips. Your repair manual will show exactly how to do this for your specific model.
3. Access the ignition switch: The switch is typically located behind the steering column. You may need to remove parts of the column or steering wheel to access it. This is the most challenging part and requires careful attention to avoid damage.
4. Disconnect the wiring harness: This is where a wiring diagram is essential. Carefully label each wire and its connection point before disconnecting. Take photos if possible. There are multiple wires and their positions are critical for proper operation.
5. Remove the ignition switch: This often involves removing screws or retaining clips holding the switch in place. Again, your repair manual will detail the procedure.
6. Install the new ignition switch: Align the new switch with the steering column and secure it using the screws or clips.
7. Reconnect the wiring harness: Reconnect the wires according to your labels and the wiring diagram. Double-check everything before proceeding.
8. Reassemble the steering column: Reinstall the shroud and any other parts you removed.
9. Reconnect the battery: Reconnect the positive (+) terminal last.
10. Test the ignition: Try the ignition switch to ensure all positions (accessory, start, etc.) work correctly. Test all lights, wipers, and other functions affected by the ignition.
Important Considerations:
* Security: Some Cavaliers have a theft-deterrent system that might require special tools or procedures.
* Airbag: Be extremely careful when working near the steering column to avoid accidentally deploying the airbag.
* Steering wheel lock: Make sure you understand how to deal with the steering wheel lock mechanism during the process.
Disclaimer: This is a generalized guide. Attempting this repair without the proper knowledge and tools can cause damage to your vehicle or even personal injury. Consult a professional mechanic if you're uncomfortable performing this repair yourself. Always prioritize safety and refer to a repair manual specific to your 1995 Chevrolet Cavalier.
