1. Preparation:
* Gather tools: You'll need a set of screwdrivers (likely Phillips and possibly flathead), possibly a panel removal tool (to avoid scratching the interior), possibly pliers or a trim removal tool, and potentially a socket set. You might also need electrical tape or connectors if you're splicing wires.
* Disconnect the battery: This is crucial to prevent accidental short circuits. Disconnect the negative (-) terminal first.
* Gather replacement parts: Make sure you have the correct replacement actuator for your specific door. You might also consider getting new screws if the old ones are damaged.
2. Accessing the Door Panel:
* Remove interior door handle: This usually involves removing screws located around the handle itself. The exact location varies by door.
* Remove the armrest/panel: This typically involves removing more screws hidden under the armrest or around the edges of the door panel. Carefully pry the panel away from the door using your trim removal tool or a flathead screwdriver (covered in cloth to protect the paint) working your way around the perimeter. Be aware of the electrical connectors for the window, power locks (if equipped), and door speakers. Unplug these carefully.
* Carefully remove the door panel: Once all screws and connectors are detached, carefully pull the door panel away from the door. It might be clipped in at various points, so take your time and avoid breaking any clips.
3. Accessing and Replacing the Actuator:
* Locate the actuator: The actuator is usually located within the door, often near the lock mechanism itself. You'll likely need to remove some screws or clips holding it in place.
* Disconnect the wiring harness: Carefully disconnect the electrical connector from the actuator. Take note of how the wires are connected for easier reassembly. A diagram or picture is highly recommended.
* Remove the old actuator: Unscrew or unclip the actuator from its mounting location. This step might require some maneuvering and potentially the use of pliers to gently remove stubborn fasteners.
* Install the new actuator: Install the new actuator in the same position as the old one, ensuring it's securely fastened.
* Reconnect the wiring harness: Carefully reconnect the electrical connector to the new actuator, making sure the wires are properly seated.
4. Reassembly:
* Reinstall the door panel: Carefully put the door panel back onto the door, making sure all the clips are properly engaged.
* Reconnect the interior door handle: Reattach the door handle and all screws.
* Reconnect the battery: Reconnect the negative (-) terminal and then the positive (+) terminal.
Important Considerations:
* 1987 Ford Explorer variations: There might be slight variations in the door panel design and actuator location depending on the trim level and specific model of your Explorer. Consult a repair manual specific to your vehicle's year and model for detailed instructions and diagrams.
* Wiring diagrams: Finding a wiring diagram for your specific Explorer is highly recommended to help with reconnecting the electrical harness correctly.
* Patience: This is not a quick job. Take your time and avoid forcing anything. Rushed work can lead to damage.
* Professional help: If you're uncomfortable working on your vehicle's interior, it's always best to seek professional help from an auto mechanic.
This is a generalized guide. Using a repair manual specific to your 1987 Ford Explorer is essential for precise instructions and to avoid damaging your vehicle. You can often find these manuals online or at auto parts stores.
