Here's a general overview of the process; however, this is not a substitute for a proper repair manual:
1. Safety First:
* Disconnect the battery: This prevents accidental short circuits.
* Wear safety glasses: Broken glass is dangerous.
* Work in a well-lit area: Good visibility is essential.
2. Gather Tools and Materials:
* New window: Ensure you get the correct replacement for your vehicle's year and model. Getting the wrong one will be a huge waste of time and effort.
* Repair manual: Absolutely crucial for specifics.
* Window removal tool (if needed): Some windows require specialized tools for removal.
* Putty knife or trim removal tool: For carefully prying interior trim pieces.
* Screwdrivers (various types): Phillips and flathead likely needed.
* Socket set: Possibly needed depending on the window regulator design.
* Safety glasses: Protect your eyes.
* Gloves: Protect your hands.
* Clean rags: For cleaning up glass fragments.
* Window adhesive (urethane): This is crucial for resealing the new window. Choose a high-quality automotive-grade adhesive.
* Caulk gun: To apply the adhesive neatly.
* Razor blade or utility knife: To carefully clean up excess adhesive.
* Clean workspace: Makes the job easier and reduces the chance of damage.
3. Removal Process (General Steps, Refer to Your Repair Manual):
* Interior Trim Removal: Carefully remove any interior trim panels that obstruct access to the window. This often involves prying gently with plastic trim removal tools to avoid scratching the interior.
* Window Regulator Access: Access the window regulator mechanism. This might involve removing parts of the door panel or quarter panel.
* Window Removal: Disconnect any wiring harnesses connected to the window motor. Then, carefully remove the window from the regulator using the appropriate tools. There may be clips or screws holding the glass in place. Take pictures as you go to help with reassembly.
* Clean the Window Channel: Thoroughly clean the window channel to remove any old adhesive, dirt, or debris. This ensures a proper seal for the new window.
4. Installation Process (General Steps, Refer to Your Repair Manual):
* Apply Adhesive: Apply a bead of automotive-grade urethane adhesive to the window channel according to the manufacturer's instructions.
* Install the Window: Carefully install the new window into the channel, ensuring it's properly seated.
* Secure the Window: Let the adhesive cure according to the manufacturer's instructions (usually several hours or overnight). This is crucial for a watertight seal.
* Reassemble: Carefully reassemble all removed interior trim panels and components.
* Reconnect the Wiring Harness: Reconnect the window motor wiring harness.
* Test the Window: Test the window to make sure it operates correctly.
Important Considerations:
* Power Windows: If your Expedition has power windows, be extra careful not to damage the wiring during removal and reinstallation.
* Glass Handling: Automotive glass is very heavy and can easily break. Handle it with care.
* Adhesive: Using the wrong adhesive can lead to leaks and window failure. Use only high-quality automotive-grade urethane adhesive.
Again, this is a general overview. A repair manual specific to your 2001 Ford Expedition is absolutely necessary for a successful repair. Attempting this without a proper manual significantly increases the risk of damage to your vehicle and personal injury. If you are not comfortable performing this repair yourself, it's best to take your Expedition to a qualified auto glass repair shop.
