Replacing a door mirror varies significantly depending on the vehicle. The process generally involves these steps, but the specifics (like fastener types, connector locations, and whether the glass is separate from the housing) will differ greatly:
General Steps (May not apply to your car):
1. Disconnect the battery: This is a safety precaution to prevent accidental short circuits.
2. Remove the interior door panel: This usually involves removing screws and possibly plastic clips around the edges of the panel. Consult a repair manual specific to your vehicle for the correct procedure.
3. Disconnect the electrical connector: Locate the electrical connector for the mirror's heating element, turn signal, and possibly other functions. Carefully disconnect it.
4. Remove the mirror mounting bolts: These are usually located behind the door panel and are accessible after removing the panel. You might need a socket wrench or other tools depending on the type of fastener.
5. Remove the mirror assembly: Carefully pull the mirror assembly away from the door. There might be some clips holding it in place.
6. Install the new mirror assembly: Reverse the removal steps to install the new mirror. Make sure the electrical connector is securely plugged in.
7. Reinstall the interior door panel: Carefully snap the door panel back into place and secure it with screws and clips.
8. Reconnect the battery: Reconnect the battery and test the mirror's functionality (heating, turn signal).
Crucially, you NEED a repair manual specific to your 2002 Ford model. These manuals provide detailed, illustrated instructions and are essential to avoid damaging your car. You can find these online (e.g., eBay, Amazon) or at auto parts stores. Attempting this repair without the correct information can lead to damage or injury.
