Tools you'll likely need:
* Screwdrivers: Phillips and possibly flathead, depending on the specific screws.
* Sockets and ratchet: Possibly needed for certain fasteners.
* Wires and connectors: You might need to unplug electrical connectors. Labeling them is crucial!
* Ignition switch removal tool (possibly): Some specialized tools can aid in releasing the switch. A repair manual will indicate if this is needed.
* Penetrating oil (like PB Blaster): This can help loosen stubborn screws or fasteners.
* Repair manual: Absolutely essential for detailed instructions and diagrams specific to your year and model.
General Steps (Refer to your repair manual for specific details):
1. Disconnect the battery: This is crucial to prevent electrical shock and damage to the vehicle's electrical system.
2. Remove the steering wheel: This is often necessary to access the ignition switch, but some Fiero models might allow access without removal. This step is complex and involves specialized tools. Again, consult your repair manual.
3. Access the ignition switch: Once the steering wheel (if necessary) is removed, you'll need to access the ignition switch itself. This usually involves removing various trim pieces and panels from the steering column. Your repair manual will detail the exact steps.
4. Disconnect electrical connectors: Carefully disconnect any electrical connectors attached to the ignition switch. Label these connectors meticulously to ensure correct reassembly. Take pictures if it helps.
5. Remove retaining screws and clips: There will be screws and/or clips holding the ignition switch in place. Carefully remove these. Penetrating oil might be helpful if they're stuck.
6. Remove the ignition switch: Once the screws and clips are removed, the ignition switch should be able to be carefully withdrawn. This may require some gentle persuasion, but avoid using excessive force. A specialized removal tool might be needed here.
7. Installation: The installation is the reverse of the removal process. Make sure everything is securely fastened and all electrical connectors are properly connected. Reconnect the battery and test the ignition system.
Important Considerations:
* Repair Manual: Using a repair manual is paramount. This detailed outline only provides a general overview.
* Safety: Disconnect the battery before starting any work. Be careful not to damage any wiring or components.
* Professional Help: If you are uncomfortable performing this task, it is best to seek help from a qualified mechanic. Replacing an ignition switch is not a trivial undertaking.
Remember: This information is for general guidance only. Always consult your vehicle's repair manual for accurate and safe instructions. Failure to follow the correct procedure could damage your vehicle or lead to injury.
