Here's a general outline, but keep in mind that variations exist depending on the specific trim level and condition of your vehicle. Always consult a repair manual specific to your 1992 Ford Explorer for the most accurate and detailed instructions. A Haynes or Chilton manual would be a great investment for this and future repairs.
Steps (General Outline - Consult your repair manual for precise details):
1. Disconnect the Negative Battery Cable: This is paramount to prevent electrical shocks or damage to your vehicle's electrical system.
2. Remove the Steering Wheel: This is often necessary to access the ignition switch. This typically involves removing the steering wheel retaining nut (after disconnecting the horn wire, if applicable), then carefully pulling the wheel off the steering column. Be prepared for a fight; the nut can be exceptionally tight. Consider using a steering wheel puller for this step to avoid damaging the wheel or column. Mark the wheel's position relative to the steering column before removal to ensure proper reinstallation and alignment.
3. Remove the Steering Column Shroud/Cover: Once the steering wheel is off, you'll need to remove the plastic shroud or cover surrounding the steering column. This usually involves removing several screws or fasteners.
4. Access the Ignition Switch: With the shroud removed, the ignition switch should be more accessible. You'll likely see a retaining clip or screws holding it in place. Again, your repair manual will provide specific instructions and diagrams for locating and removing these fasteners.
5. Disconnect the Wiring Harness: Carefully disconnect the wiring harness from the ignition switch. It's wise to take pictures or make a diagram before disconnecting to ensure proper reconnection later. Note the positions of all connectors.
6. Remove the Ignition Switch: Once the wiring harness is disconnected, you should be able to carefully remove the ignition switch itself. There might be a retaining clip or screw holding it in place, or it might just pull straight out.
7. Install the New Ignition Switch (if replacing): If you are replacing the ignition switch, install the new one, ensuring that all connections are securely reconnected according to your diagram/photo.
8. Reassemble: Carefully reverse the steps above to reassemble the steering column shroud, steering wheel, and reconnect the battery.
Important Considerations:
* Special Tools: You may need specialized tools such as a steering wheel puller, various socket sizes, and possibly a small screwdriver set.
* Caution: Be extremely careful when working around the steering column and ignition system. Improper handling can damage components or lead to injury.
* Repair Manual: This is not a substitute for a detailed repair manual. The steps above are a *general* outline and may vary considerably. Using a repair manual specific to your 1992 Ford Explorer is essential for successful completion of this repair.
This process is complex and potentially risky if not done correctly. If you're not comfortable performing this repair yourself, it's highly recommended that you take your vehicle to a qualified mechanic. Improper installation could lead to serious problems, including starting issues, and even security risks.
