1. Preparation:
* Gather tools: You'll need a trim panel removal tool (plastic pry tool is ideal to avoid scratching), a Phillips head screwdriver, and possibly a flathead screwdriver (used cautiously).
* Protect the door: Lay down a towel or blanket inside the door to prevent scratching.
2. Remove interior components:
* Window crank handle: Usually pops off or unscrews.
* Door handle: This often involves removing screws or a retaining clip under the cover. The specific method varies depending on your model.
* Power window switch panel (if equipped): This is usually held on by screws or clips.
* Door lock actuator (if equipped): You might need to disconnect the electrical connector to the actuator.
3. Remove the door panel:
* Locate the screws: Most 1998 Expeditions have screws along the edge of the panel, hidden behind the components you just removed (e.g., under the armrest, around the window crank, etc.). Remove these screws.
* Release the clips: Once the screws are removed, the door panel is held on by plastic clips. These are usually located around the perimeter of the panel. Start at the bottom and gently pry the panel away from the door using your trim removal tool. Work your way around, releasing the clips one at a time. Use even pressure to avoid breaking the clips.
* Disconnect the electrical connectors: There will be one or more electrical connectors (for the door lock, power window, etc.) that need to be disconnected. Gently push the connector tabs to release them.
4. Remove the door panel completely:
* Once all the clips are released and the connectors are disconnected, carefully pull the door panel away from the door. Be mindful of any remaining wires or cables.
Important Considerations:
* Clips: These plastic clips are fragile. Take your time and use the trim removal tool carefully to avoid breaking them. Replacement clips are readily available at auto parts stores.
* Wiring: Be gentle with the wiring harnesses. Don't pull on them forcefully.
* Repair Manual: A repair manual specific to your vehicle will provide detailed instructions and diagrams. This is highly recommended. You can find these online or at auto parts stores.
Disclaimer: This is a general guide. Following these instructions incorrectly could damage your vehicle. If you are uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
