Here's a general outline of the steps. This is not a comprehensive guide and may not be completely accurate for your specific vehicle. Always consult a repair manual specific to your 1999 Lincoln Town Car for detailed instructions and diagrams. A factory service manual is highly recommended.
1. Disconnect the Battery: Disconnect the negative (-) battery terminal. Wait a few minutes to allow any residual charge to dissipate.
2. Remove the Steering Wheel: You'll need a steering wheel puller for this. This usually involves removing the horn contact, the steering wheel retaining bolt, and then using the puller to carefully remove the wheel. Be extremely careful here, as the airbag system is involved. If you're uncomfortable with this step, it's best to have a professional handle it.
3. Access the Steering Column: This usually involves removing parts of the dashboard or lower steering column shroud. The specific components will depend on your Town Car's trim level. Your repair manual will show exactly what needs to be removed.
4. Disconnect Electrical Connections: There will be several electrical connectors attached to the steering column, including those for the turn signals, wipers, cruise control, and possibly others. Carefully disconnect these connectors, noting their locations for reassembly. Take photos if necessary.
5. Disconnect Mechanical Linkages: This includes the ignition lock cylinder and possibly other linkages for the steering column. These connections may require special tools for removal.
6. Remove the Steering Column Bolts: Locate the bolts securing the steering column to the vehicle's frame. These are usually underneath the dashboard. Remove these bolts carefully.
7. Lower the Steering Column: Once all the bolts are removed, you should be able to carefully lower the steering column. It may be necessary to support the column as you lower it to prevent damage.
8. Complete Your Repair: Once the steering column is dropped, you can access the components you need to repair or replace.
Important Considerations:
* Airbag System: The airbag system is crucial and potentially dangerous. If you're not experienced with working on airbag systems, you should have a professional handle this. Improper handling can lead to accidental deployment and serious injury.
* Repair Manual: A factory service manual specific to your 1999 Lincoln Town Car is absolutely essential. It will provide detailed instructions, diagrams, torque specifications, and safety precautions.
* Safety: Always wear safety glasses and gloves when working on your vehicle.
* Professional Help: If you're not comfortable with any of these steps, it's best to take your vehicle to a qualified mechanic.
