Here's a general outline of the process. Remember this is a *general guideline* and may vary slightly based on your specific model and trim:
1. Preparation and Safety:
* Disconnect the battery's negative terminal. This is crucial to prevent electrical shocks and short circuits.
* Gather your tools: You'll need screwdrivers (Phillips and possibly flathead), possibly sockets and wrenches, a wiring diagram (your repair manual will have this), possibly a lock pick set (depending on the ignition lock cylinder removal method), and the new ignition switch.
* Take pictures: Before disconnecting anything, take plenty of pictures. This will be invaluable when reassembling.
2. Accessing the Ignition Switch:
* Steering column removal (often necessary): This is usually the most challenging part. You'll likely need to remove the steering wheel, the steering column shroud (plastic cover), and potentially some parts of the steering column itself. This often involves loosening or removing bolts and potentially disconnecting wiring harnesses. Your repair manual will have the correct procedure. Be aware that some models require special tools for steering wheel removal (to avoid damaging the airbag).
* Accessing the ignition switch: Once the steering column is sufficiently exposed, you should be able to locate the ignition switch. It's usually mounted behind the steering column, often secured by screws or a retaining clip.
3. Removing the Old Ignition Switch:
* Disconnect the wiring harness: Carefully disconnect the wiring harness connectors from the ignition switch. Again, take pictures or make notes to ensure correct reconnection.
* Remove the switch: Remove the screws or clips holding the ignition switch in place. Carefully remove the old switch from its housing.
4. Installing the New Ignition Switch:
* Install the new ignition switch: Carefully install the new ignition switch into its housing, aligning it correctly.
* Reconnect the wiring harness: Reconnect the wiring harness connectors to the new ignition switch, ensuring each wire is in its correct position. Refer to your pictures and/or the wiring diagram.
* Secure the switch: Secure the new switch in place with the appropriate screws or clips.
5. Reassembly:
* Reassemble the steering column: Carefully reassemble the steering column and steering wheel, making sure everything is properly aligned and secured.
* Reconnect the battery: Reconnect the battery's negative terminal.
* Test the new ignition switch: Test the ignition switch to ensure it functions correctly. Try all ignition positions (accessories, start, etc.).
Important Considerations:
* Airbag: If your LeBaron has an airbag, you must be extremely careful when working around the steering wheel and column. Disconnecting the airbag incorrectly can cause it to deploy unexpectedly, causing serious injury.
* Security: The ignition switch may be integrated with the lock cylinder. This means you might need a special tool to remove the lock cylinder before you can replace the switch.
* Professional help: If you are not comfortable with this repair, it's best to take your vehicle to a qualified mechanic. Improper installation could cause significant damage to your vehicle's electrical system or even lead to a dangerous situation.
This is a complex repair. Do not attempt this without a detailed repair manual for your specific 1993 Chrysler LeBaron. The repair manual will provide the step-by-step instructions with illustrations, making the process much safer and easier.
