1. Safety First:
* Disconnect the battery's negative terminal. This prevents accidental short circuits.
2. Access the Window Mechanism:
* Door Panel Removal: This is usually the most challenging part. You'll need to remove the interior door panel. This typically involves removing screws around the armrest, door handle, and possibly some under the speaker grille. There are usually plastic clips holding the panel in place; carefully pry these loose using plastic trim removal tools to avoid breaking them. Consult your repair manual for the exact procedure.
3. Identify the Problem:
* Inspect the Regulator: Carefully examine the window regulator (the mechanism that moves the window). Look for broken parts, bent tracks, or detached cables. The window may have simply popped off the track.
* Inspect the Tracks: Check the condition of the window tracks. Are they bent, damaged, or dirty? Clean them with a brush and degreaser if necessary.
4. Common Issues and Solutions:
* Window popped off track: Gently maneuver the window back onto the tracks. This often requires some maneuvering and might involve using a tool to guide it.
* Broken regulator cable: This requires replacing the entire window regulator. You'll need a new one from an auto parts store (make sure it's the correct part number for your vehicle). Replacing the regulator involves removing the old one and installing the new one, often following the reverse steps of removal. This is the most complex part.
* Bent tracks: This might be repairable with careful bending, but often replacement is easier.
* Broken or dislodged clips: These small plastic clips are crucial for keeping the window on track. Replacement clips might be necessary.
5. Reassembly:
* Reinstall the Window: Once the regulator is repaired or replaced, and the tracks are clean and aligned, carefully reinstall the window, ensuring it's properly seated in the tracks.
* Reinstall the Door Panel: Reassemble the door panel, carefully lining up all the clips and screws.
Tools You Might Need:
* Plastic trim removal tools: Essential for removing the door panel without damage.
* Screwdrivers (Phillips and flathead): Various sizes.
* Pliers: For working with the regulator and clips.
* Socket wrench set: Possibly needed for certain screws.
* New window regulator (if necessary): Ensure you get the correct part number.
* Repair manual specific to your 2002 Lincoln LS: Absolutely crucial for detailed instructions and diagrams.
Important Considerations:
* If you're not comfortable with this type of repair, take your car to a qualified mechanic. It's much better to have a professional handle it than risk further damage.
* Take pictures throughout the disassembly process. This will help you remember how everything goes back together.
