1. Assessment:
* Safety First: Disconnect the negative battery terminal before starting any work.
* Identify the Problem: Is the window completely detached? Is the motor running but the window not moving? Is there a broken cable or other visible damage? Understanding the specific issue helps determine the best course of action.
2. Parts and Tools:
* Replacement Window Regulator: This is the most likely culprit. You can find these online (eBay, Amazon, auto parts stores) or at a local parts store. Make sure to specify it's for a 2000 Mercury Villager driver's side.
* Screwdrivers (Phillips and flathead): Various sizes.
* Socket Set: Likely needed for certain bolts.
* Pliers: Needle-nose pliers can be helpful.
* Panel Removal Tools: These plastic tools help avoid scratching the door panels. (Highly recommended)
* Wrench: Possibly needed.
* Shop rags or paper towels: To keep things clean.
* Optional: Torque wrench: For tightening bolts to the manufacturer's specifications.
3. Repair Process (General Steps):
This is a general outline. The exact steps might vary slightly depending on the specific year and model. Consult a repair manual specific to your vehicle for detailed instructions and diagrams.
* Remove the Door Panel: This usually involves removing screws around the armrest, door handle, and possibly under the window crank/switch panel. Carefully pry the panel away using your panel removal tools. There may be clips holding it in place, so work slowly to avoid breakage. Take pictures as you go to help with reassembly.
* Access the Window Regulator: Once the door panel is removed, you'll see the window regulator mechanism.
* Assess the Damage: Inspect the regulator for broken cables, stripped gears, or other damage. If the motor is working but the window isn't moving, a broken cable is likely the issue. If the motor doesn't run, the motor itself might be faulty.
* Replace the Regulator (if necessary): Disconnect the motor connector and any other connections. Carefully remove the old regulator, taking note of how it's attached. Install the new regulator, following the reverse order of removal. Make sure the window is properly connected to the new regulator.
* Reconnect the Motor and Other Connections:
* Reinstall the Door Panel: Carefully put the door panel back in place, securing all the screws and clips.
* Test the Window: Reconnect the battery and test the window to ensure it operates correctly.
4. Repair Manual:
A repair manual specific to your 2000 Mercury Villager is highly recommended. These manuals provide detailed diagrams and step-by-step instructions that are far more precise than a general description. You can find these online (often as downloadable PDFs) or at auto parts stores.
Important Considerations:
* Window Removal: You may need to temporarily remove the window glass to access certain parts of the regulator. Be very careful as the glass is heavy and can break. Support the glass with a suitable tool or rope as you work.
* Professional Help: If you're not comfortable with auto repair, don't hesitate to take it to a professional mechanic. Improper repair can lead to further damage.
This is a complex repair; taking pictures at each step is crucial for reassembly. A repair manual is your best friend for this job. Remember to prioritize safety throughout the entire process.
