Tools You'll Need:
* Socket set: Various sizes, likely including 7/16", 1/2", and possibly others depending on your specific vehicle.
* Ratchet and extensions: To reach the ignition switch.
* Screwdrivers: Phillips and flathead, likely.
* Wire strippers/crimpers (optional but recommended): If you need to replace any damaged wires.
* Needle-nose pliers: For manipulating small parts.
* New ignition switch: Make sure you get the correct replacement part for your specific 1993 Ford Explorer. Your VIN will help ensure you get the right one. You can find parts at auto parts stores or online retailers.
* Shop Manual (Highly Recommended): A repair manual specific to your year and model Ford Explorer will be invaluable. It will have detailed diagrams and instructions, making the process much easier and less prone to errors.
Steps (General Outline – Consult your repair manual for precise details):
1. Disconnect the negative battery terminal. This is crucial to prevent electrical shorts and injury.
2. Remove the steering column shroud: This usually involves removing screws and possibly some plastic clips. The exact procedure will vary depending on your trim level and the specific Explorer. Your repair manual will show you exactly how to do this.
3. Remove the ignition switch: This is where a shop manual becomes essential. The ignition switch is usually secured by screws or a retaining clip behind the steering column. You may need to remove the steering column itself, at least partially (some models allow for easier switch access without fully removing the column). Be extremely careful not to damage any wires or the steering column itself.
4. Disconnect the wiring harness: Carefully disconnect the wiring harness from the old ignition switch. Take pictures or make notes to remember how everything connects. The wiring harness connectors often have a release tab or lever; carefully release them to avoid damage.
5. Install the new ignition switch: Carefully install the new ignition switch, making sure it's seated correctly. Reconnect the wiring harness according to your notes or pictures. Double-check everything to make sure you have everything connected properly.
6. Reassemble: Carefully put everything back together—the steering column shroud and any other components you removed.
7. Reconnect the negative battery terminal.
8. Test the ignition system: Turn the key in the ignition switch to test all positions (accessory, ignition, start).
Important Considerations:
* Steering Wheel Lock: Be aware of the steering wheel lock mechanism. You may need to work around it carefully.
* Wiring Diagrams: The wiring harness can be complex. A wiring diagram from your repair manual is crucial to avoid errors.
* Security System: If your Explorer has a factory alarm or aftermarket security system, this could complicate the process. Consult the manual for your security system if you have one.
* Professional Help: If you're uncomfortable working on your vehicle's electrical system or aren't mechanically inclined, it's best to take it to a qualified mechanic. A small mistake can lead to bigger problems.
This is a general guideline. Always consult a repair manual specific to your 1993 Ford Explorer before attempting this repair. This will provide the accurate and detailed instructions specific to your vehicle, significantly increasing your chances of success and avoiding damage. The information above is for guidance only and does not replace the need for a proper shop manual.
