I strongly advise against attempting this yourself unless you have significant mechanical experience and the correct tools. This is a job best left to a qualified mechanic. Incorrectly removing the ignition switch can lead to costly repairs or even render your vehicle inoperable.
However, if you're determined to proceed, here's a general outline of the steps involved. Keep in mind that this is a *general guide only*, and the specific steps will differ considerably based on your van's model:
1. Consult a repair manual: Obtain a repair manual specific to your Ford van's year and model. This is crucial as it will provide detailed, illustrated instructions and torque specifications. A Haynes or Chilton manual is a good starting point.
2. Disconnect the battery: This is the most important safety step to prevent accidental short circuits. Disconnect both the positive (+) and negative (-) battery terminals.
3. Remove the steering column cover: This usually involves removing screws or clips. The location and method vary greatly depending on the van. Your repair manual will show you precisely how to do this.
4. Remove the ignition switch: This is where things get tricky. You will likely need specialized tools to release the ignition switch. This may involve:
* Removing the ignition cylinder: This often requires a special tool to depress the retaining pin or clip.
* Disconnecting wiring harnesses: Carefully disconnect the electrical connectors attached to the ignition switch. Label the wires or take pictures to avoid confusion during reassembly.
* Removing mounting screws or bolts: The ignition switch is usually held in place by screws or bolts. These need to be removed carefully.
5. Install the new ignition switch: Once the old switch is removed, carefully install the new one, ensuring that all wiring harnesses are correctly connected.
6. Reassemble everything: Carefully put everything back together in reverse order, ensuring that all screws and clips are securely fastened.
7. Reconnect the battery: Reconnect the battery terminals.
8. Test the ignition system: Turn the key to check if the ignition system is working correctly.
Again, I strongly emphasize the importance of using a repair manual specific to your vehicle and seeking professional help if you are unsure about any step. Improperly working on your vehicle's ignition system can be dangerous. The cost of professional repair will likely be far less than the cost of a damaged ignition system or other unforeseen issues.
