However, if you're determined to tackle this yourself, here's a general outline. These instructions are a guideline only and may not be perfectly accurate for your specific vehicle. Always consult a repair manual specific to your 1992 Ford Tempo for precise instructions and diagrams.
Tools you'll likely need:
* Repair Manual: Absolutely essential for specific instructions and torque specifications.
* Screwdrivers: Phillips and flathead, various sizes.
* Socket set: Metric, with various sizes and extensions.
* Wrench set: Metric, for various bolt sizes.
* Pliers: Needle-nose and regular.
* Wire strippers/crimpers: If you need to replace any wiring.
* Multimeter: To test the electrical connections (highly recommended).
* Penetrating oil (PB Blaster or similar): To help loosen any stubborn screws or bolts.
* Protective eyewear and gloves: Always wear these when working on your car.
General Steps (Consult your repair manual for specifics):
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Steering Wheel Removal (May Be Necessary): Depending on the access required, you may need to remove the steering wheel. This involves special tools and is a potentially hazardous procedure if not done correctly. Refer to your repair manual for the precise steps.
3. Remove the Steering Column Shroud: This plastic cover surrounds the steering column and needs to be removed to access the ignition switch. It's usually held on by screws.
4. Remove the Ignition Switch: This is the most challenging part. The switch is usually held in place by screws or a retaining clip. You'll need to carefully disconnect the wiring harness connected to the switch. Take photos or make detailed notes of the wiring connections before disconnecting anything. This will be crucial for reassembly.
5. Install the New Ignition Switch: Carefully install the new switch, ensuring all the wiring harnesses are connected correctly. Refer to your photos or notes. Double-check all connections.
6. Reassemble Everything: Carefully put everything back together in the reverse order of disassembly. Make sure all screws and bolts are tightened to the correct torque specifications (found in your repair manual).
7. Reconnect the Battery: Reconnect the positive (+) terminal last.
8. Test the Ignition System: Turn the key to start the car and verify that everything is working correctly. Test all ignition positions (accessory, run, start).
Important Considerations:
* Key Programming: Some ignition switches require programming to your car's key. You may need a special tool or the assistance of a locksmith or dealer to do this.
* Wiring Diagrams: Use wiring diagrams from your repair manual to properly connect the wiring harness. Making a mistake here can cause electrical damage or prevent the vehicle from starting.
* Security System: If your car has an aftermarket security system or immobilizer, it may be necessary to have it reprogrammed after replacing the ignition switch.
Again, this is a general guideline only. Consult a repair manual specific to your 1992 Ford Tempo before attempting this repair. If you are uncomfortable with any part of this process, please take your car to a qualified mechanic. Improper repair could lead to serious consequences.
