Before you begin:
* Disconnect the negative battery terminal. This prevents accidental short circuits.
* Gather your tools. You'll likely need a trim panel removal tool (plastic pry tool), screwdrivers (Phillips and possibly flathead), and possibly a socket wrench.
Removing the Door Panel (General Steps):
1. Remove the Interior Door Handle: There are usually screws hidden behind the handle itself (you might need to pry it gently to reveal them).
2. Remove the Window Crank/Switch Panel: This usually involves removing screws or possibly popping it off with a trim tool.
3. Remove the Door Pocket: This often just pops out after removing screws holding it in place.
4. Locate and Remove Screws: There will be several screws holding the door panel to the door. These are often located around the edges of the panel (bottom, armrest area, and possibly near the speaker). Use a trim tool to carefully pry the panel away from the door, working your way around the edges.
5. Disconnect Electrical Connectors: After removing the screws, carefully disconnect the electrical connectors for the door lock, window switch, and power mirror if applicable. These connectors usually have a release tab or clip. Note their placement for easy reassembly.
6. Remove the Door Panel: Carefully pry the panel away from the door, using your trim tool to avoid scratching the door. The panel is usually clipped in place around the perimeter. Work slowly and steadily to avoid breaking any clips.
Once the panel is off:
You should be able to see the window regulator mechanism. Carefully examine it to see exactly how the window has come off track. The problem could be a dislodged roller, broken cable, or a detached regulator. Repairs vary depending on the specific issue. YouTube videos can be helpful for visualizing the repair process, but again, reference a repair manual for your specific vehicle.
Reassembly:
Reverse the steps above to reassemble the door panel. Make sure all the electrical connectors are securely connected and the screws are tightened.
Important Considerations:
* Clips: Be very careful not to break the plastic clips that hold the door panel in place. Replacement clips are usually available at auto parts stores.
* Patience: This process can be time-consuming and requires patience. Take your time and avoid using excessive force.
* Professional Help: If you're not comfortable working on your car, consider taking it to a professional mechanic.
Remember, this is a general guide. A repair manual specific to your 1999 Ford Expedition is crucial for accurate and safe completion of this repair. Consult that manual throughout the process.
