However, here's a general overview of the process. This is not a complete guide and should only be used in conjunction with a proper repair manual:
1. Disconnect the battery: This is crucial to prevent electrical shorts and injury. Disconnect both the positive (+) and negative (-) terminals.
2. Remove the steering wheel: This often involves using a steering wheel puller. This step is usually necessary to access the ignition cylinder. The specifics vary depending on the steering wheel type. Again, consult your repair manual.
3. Remove the bezel/trim around the ignition switch: This usually involves carefully prying it off with a trim removal tool to avoid scratching.
4. Access the ignition lock cylinder: Once the bezel is off, you'll likely see a retaining clip or screw holding the ignition cylinder in place. The exact method will depend on your Blazer's model.
5. Remove the retaining clip or screw: Carefully remove the fastener(s) holding the cylinder.
6. Remove the ignition lock cylinder: Once the fastener is removed, the cylinder should be able to be pulled out. There may be a slight resistance. Do not force it. If it's stuck, there might be a secondary retaining mechanism you haven't identified yet. Consult your repair manual.
7. Replace the ignition lock cylinder (if needed): Installation is the reverse of removal. Make sure to align everything properly before securing it.
Important Considerations:
* Key Position: The ignition should be in the "off" position.
* Wiring: Take note of how any wires are connected before disconnecting them. Photographing the connections can be very helpful.
* Special Tools: You may need specialized tools, such as a steering wheel puller, trim removal tools, and possibly a special tool for removing the ignition cylinder.
* Security: Replacing the ignition cylinder often requires getting a new ignition key cut to match the new cylinder.
* Professional Help: If you are uncomfortable with this procedure or lack the necessary tools and experience, it's best to take your vehicle to a qualified mechanic. This is a delicate procedure, and improper execution can lead to significant damage.
This is a simplified explanation. Always refer to a repair manual specific to your 1996 Chevy Blazer for detailed instructions and diagrams. Failure to do so could lead to damage to your vehicle and potential injury.
