However, if you're determined to attempt it yourself, here's a general outline. Remember to always disconnect the negative battery terminal before starting any electrical work!
1. Identify the Problem:
* Broken Key: This might just require replacing the key cylinder.
* Faulty Ignition Switch: The switch itself might be malfunctioning, causing starting problems or erratic behavior.
* Wiring Issues: A less common cause, but damaged wiring could also lead to ignition problems.
2. Gather Tools and Parts:
* New Ignition Switch (or Cylinder): Order the correct part for your specific 1996 Cavalier model. The part number will vary depending on the trim level and options.
* Screwdrivers (Phillips and flathead): Sizes will vary.
* Socket set and ratchet: This will depend on the specific bolts and screws you encounter.
* Wire connectors/crimpers (if wiring is damaged): Important if you need to replace or repair wiring.
* Multimeter (optional): Helpful for testing the electrical system if you suspect a wiring problem.
* Shop manual (highly recommended): A factory or aftermarket service manual will provide detailed diagrams and instructions specific to your vehicle's year and model. This is invaluable.
3. Access the Ignition Switch:
* Steering Wheel Removal (Possibly): In some cases, you may need to remove the steering wheel to access the ignition switch. This requires specialized tools and is a more advanced procedure. Consult your service manual.
* Steering Column Removal (Possibly): Even more complex than steering wheel removal, this may also be necessary depending on your Cavalier’s configuration. This is definitely a job best left to experienced mechanics.
* Lower dash panel removal: You'll likely need to remove some lower dash panels to reach the ignition switch. This usually involves removing screws and possibly some clips.
4. Replacing the Ignition Switch (or Cylinder):
* Disconnect the Wiring Harness: Carefully disconnect the wiring harness connected to the ignition switch. Take pictures or make a diagram to help you remember how everything goes back together.
* Remove the Old Switch (or Cylinder): This will likely involve removing screws or bolts securing the switch to the steering column.
* Install the New Switch (or Cylinder): Carefully install the new switch, ensuring that all connections are properly seated.
* Reconnect the Wiring Harness: Reconnect the wiring harness, referring to your pictures or diagram.
* Reassemble: Carefully reassemble the dash panels and steering wheel (if removed).
5. Test:
* Connect the Battery: Reconnect the negative battery terminal.
* Test the Ignition: Try the ignition switch to ensure it functions correctly.
Important Considerations:
* Security System: If your Cavalier has a factory anti-theft system, replacing the ignition switch might trigger it. You might need to have the system reprogrammed by a qualified locksmith or mechanic.
* Airbag System: Be extremely careful around the steering wheel and airbag components. Accidental deployment can cause serious injury.
* Professional Help: If you encounter any difficulties or are unsure about any step, seek professional assistance. A damaged ignition system can be costly to repair.
This is a simplified overview. It's strongly recommended you consult a repair manual specific to your 1996 Chevrolet Cavalier before attempting this repair. Improperly installing the ignition switch can damage your vehicle's electrical system or even prevent the car from starting. Take your time, be methodical, and prioritize safety.
