Here's a general outline of the process. This is NOT a comprehensive guide and may not cover all possible variations. Consult a repair manual specific to your 1999 Ford Expedition for detailed instructions and diagrams. Improper removal can damage the dashboard or other components.
1. Locate the Actuator: This is usually located behind the dashboard, near the HVAC system. Accessing it will require removing parts of the dashboard. The location varies depending on which blend door you're working on. Consult a repair manual for precise location.
2. Remove Obstructions: This will likely involve removing the glove box (passenger side actuators) or parts of the center console or radio/climate control bezel to gain access to the actuator. This often involves removing screws and possibly some plastic clips. Be careful not to break any plastic clips.
3. Disconnect the Electrical Connector: Once you've accessed the actuator, carefully disconnect the electrical connector. It usually has a release tab or clip that needs to be pressed or pushed to release the connector.
4. Remove the Actuator: The actuator is typically held in place by screws or clips. Carefully remove these fasteners. Take pictures as you go to help you remember how everything goes back together. The actuator itself might be difficult to reach; you might need to use extensions or flexible tools.
5. Replace the Actuator: Install the new actuator, making sure it's properly seated and all fasteners are tightened. Reconnect the electrical connector.
6. Reassemble: Carefully reinstall all the parts you removed earlier, making sure everything is properly aligned and secured.

* Patience: This is often a time-consuming job that requires patience and attention to detail.
* Alternative: If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
