Here's a breakdown of how to fix it:
1. Safety First:
* Disconnect the battery: This is crucial to prevent accidental short circuits.
* Work in a well-lit area: You'll need to see clearly what you're doing.
2. Access the Window Regulator:
* Remove the door panel: This process varies slightly depending on the specific door (front or rear), but generally involves removing screws around the armrest, door handle, and possibly other interior trim pieces. Consult a repair manual (online or from a parts store) specific to your year and model for detailed instructions. These manuals often have diagrams showing screw locations and panel removal steps.
* Locate the window regulator: Once the door panel is off, you'll see the window regulator mechanism. This is the assembly that moves the window up and down.
3. Re-attach the Window to the Regulator:
* Inspect the regulator: Check for any broken parts or damage to the regulator itself. If it's significantly damaged, you might need a replacement.
* Identify the problem: Determine exactly *how* the window came off the track. Was it a single roller that popped out? Did the entire window detach? Is the regulator arm broken?
* Re-attach the window: Carefully guide the window back onto the regulator track. This might involve gently manipulating the window and the regulator components. If a roller came off, you may need to use small pliers or similar tools to carefully realign it.
* Test the window: Before reassembling everything, carefully test the window mechanism by operating the switch. Make sure the window moves smoothly up and down without binding or making unusual noises.
4. Reassemble:
* Replace the door panel: Carefully put the door panel back on, ensuring all screws and clips are securely fastened.
Tools You Might Need:
* Screwdrivers (Phillips and flathead)
* Panel removal tools (to avoid scratching the panel)
* Pliers (possibly needle-nose)
* Repair manual (highly recommended!)
* Possibly a new window regulator (if the old one is damaged)
If you are not comfortable working on car repairs yourself, take your Expedition to a qualified mechanic. Improperly repairing the window regulator can lead to further damage or even injury. They have the experience and tools to do the job correctly. Attempting this repair yourself could potentially void any warranty you may have.
