Tools you'll likely need:
* Socket set: Various sizes, including metric and standard.
* Screwdrivers: Phillips and flathead, various sizes.
* Pliers: Needle-nose and regular.
* Wire strippers/crimpers: If you need to replace wiring.
* Test light or multimeter: To check wiring connections.
* Owners manual or repair manual: Essential for specifics to your vehicle.
Procedure (General Steps – Consult your manual for precise details):
1. Disconnect the battery: This is crucial to prevent electrical shocks and short circuits. Disconnect the negative (-) terminal first.
2. Steering column removal (may or may not be necessary): Depending on your Chevelle's configuration, you might need to partially or fully remove the steering column. This is often the most challenging part. It will involve removing bolts, potentially the steering wheel (after marking its position!), and possibly the column's lower bearing. Your repair manual will show you exactly how to do this safely and correctly.
3. Access the ignition switch: Once you have access to the steering column's mechanism, you'll locate the ignition switch itself. It's usually secured with screws or a retaining clip. The exact location and method of securing it vary. Refer to your repair manual.
4. Disconnect wiring harness: Carefully disconnect the wiring harness from the ignition switch. Before doing so, take pictures or make a detailed diagram of each wire's connection. You'll need this information to reassemble correctly. Use a label maker or masking tape and pen to label wires if necessary.
5. Remove the old ignition switch: Once the wiring is disconnected, remove the old switch from its mounting. This might involve removing screws or carefully prying it loose. Again, consult your repair manual for the correct procedure.
6. Install the new ignition switch: Carefully install the new ignition switch, making sure it's properly seated and aligned.
7. Reconnect the wiring harness: Reconnect the wiring harness to the new ignition switch, following your diagram or pictures. Double-check each connection to ensure correct placement.
8. Reassemble everything: Reassemble the steering column (if removed), securing all bolts and parts.
9. Reconnect the battery: Reconnect the positive (+) terminal.
10. Test the ignition system: Turn the ignition key to verify that all functions (starter, lights, accessories) work correctly.
Important Considerations:
* Wiring: The wiring harness for the ignition switch can be fragile. Be extremely careful not to damage the wires.
* Safety: Working on a car's electrical system requires caution. Always disconnect the battery before starting any work.
* Professional Help: If you're not comfortable working on your car's electrical system or steering column, it's best to take it to a qualified mechanic. Improperly installed ignition switch can lead to serious problems.
Remember, this is a general guide. A 1969 Chevelle repair manual is absolutely essential for performing this repair correctly and safely. The specific procedures will vary depending on your car's model and options. Using the wrong manual could lead to damage or injury.
