1. Preparation:
* Disconnect the battery: This is crucial to prevent short circuits and injury. Disconnect the negative (-) terminal first.
* Gather tools: You'll likely need a set of trim removal tools (plastic pry tools are ideal to avoid scratching), screwdrivers (Phillips and possibly flathead), possibly a socket wrench and possibly a Torx driver, depending on your vehicle's year. Refer to your specific year's repair manual for the exact tools required.
* Consult a repair manual: A Haynes or Chilton manual specific to your Ford Focus year and model is invaluable. It will provide diagrams and precise instructions tailored to your car. Online resources like forums specific to your Ford Focus model year can also be helpful.
2. Accessing the Window Motor:
* Door panel removal: This is the most significant step. You'll need to carefully remove the interior door panel. This usually involves:
* Removing the door handle cover (often held on by small screws or clips).
* Removing any screws or bolts securing the door panel.
* Carefully prying the door panel away from the door using trim tools. There are usually several clips holding it in place. Work slowly and deliberately to avoid breaking the clips. Once you've released the clips around the perimeter of the panel, it should come off.
* Locate the window regulator and motor: Once the door panel is removed, you should see the window regulator mechanism and the electric window motor attached to it. The location and access will vary slightly depending on the year and model.
3. Removing the Window Motor:
* Disconnect the electrical connector: Unplug the electrical connector leading to the window motor.
* Remove mounting screws or bolts: The motor is usually held in place by screws or bolts. Locate and carefully remove these fasteners. Again, your repair manual is essential here to identify the correct fasteners and their locations.
* Remove the motor: Once the fasteners are removed, the motor should be free to remove.
4. Reassembly:
Reassembly is the reverse of the removal process. Make sure all clips and fasteners are securely reattached. Reconnecting the electrical connector is also vital. Test the window operation after reassembly.
Important Considerations:
* Year and model: The exact procedure varies between Ford Focus years. Do not rely on general instructions; always use a repair manual specific to your car.
* Care with clips: Door panel clips are easily broken. Work carefully and use the correct tools to avoid damage.
* Wiring: Take pictures or make notes of the wiring connections before disconnecting anything to help with reassembly.
* Safety: Always disconnect the battery before starting any work on the electrical system.
This is a general overview. Without knowing the specific year and model of your Ford Focus, I cannot provide more precise instructions. Consult a repair manual appropriate for your car's year and model for detailed, accurate instructions and diagrams. If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
