Safety First!
* Disconnect the negative battery terminal before starting any work. This prevents accidental shorts and electrical shocks.
Tools You'll Likely Need:
* Socket set (various sizes)
* Screwdrivers (Phillips and flathead)
* Wire cutters/strippers (possibly)
* Pliers
* A new ignition switch assembly (make sure you get the correct one for your Cavalier)
* Optional: Electrical tester (multimeter) to verify wiring
General Steps (Consult your repair manual for precise details):
1. Steering Column Removal (Possibly): Depending on the design, you might need to partially or fully remove the steering column. This typically involves removing the steering wheel (requires a special tool), and detaching the column from the dashboard. This is the most challenging part and requires careful attention. Your repair manual will provide detailed instructions for this step.
2. Access the Ignition Switch: Once you have access to the steering column, you'll see the ignition switch assembly. It's usually held in place by screws or a retaining clip. The location and method of securing will vary.
3. Disconnect Electrical Connections: Carefully disconnect the wiring harness connectors from the ignition switch. Take photos or make detailed notes of the wiring connections before disconnecting them to ensure correct reassembly.
4. Remove the Ignition Switch: Remove the screws or clips holding the ignition switch in place. Carefully remove the switch from the steering column.
5. Install the New Ignition Switch: Install the new ignition switch, making sure it's properly seated. Secure it with the screws or clips.
6. Reconnect Electrical Connections: Reconnect the wiring harness connectors to the new ignition switch, matching them exactly to how they were before.
7. Reassemble: Reinstall the steering column (if you removed it), securing all components properly.
8. Reconnect the Battery: Reconnect the negative battery terminal.
9. Test: Test the new ignition switch by turning the key to the "Start," "Accessory," and "Off" positions. Check all functions like headlights and radio to ensure they work correctly.
Important Considerations:
* Key: The new ignition switch may come with a new key, or you may need to have your existing key cut to match.
* Anti-theft System: If your Cavalier has an anti-theft system, you may need to have it reprogrammed after replacing the ignition switch.
* Wiring Diagrams: A wiring diagram for your specific year and model is essential to ensure you connect everything correctly. Your repair manual should have this.
