1. Preparation:
* Safety First: Disconnect the negative battery terminal to prevent accidental short circuits.
* Gather Tools: You'll need a variety of tools, likely including: sockets (various sizes), ratchet, extensions, screwdrivers (Phillips and possibly flathead), possibly a trim removal tool, pliers, and a new rear wiper motor. Consult your vehicle's repair manual for the specific socket and bolt sizes.
* Consult a Repair Manual: A factory service manual or a reputable online repair guide specific to your 2007 Ford Explorer is highly recommended. This will provide detailed diagrams and torque specifications, preventing damage to your vehicle.
2. Accessing the Wiper Motor:
* Interior Access (Most Likely): The rear wiper motor on many 2007 Explorers is accessed from the interior of the vehicle, through the cargo area. You'll likely need to remove the interior trim panels around the rear hatch or liftgate. This often involves carefully prying off plastic clips. Be gentle to avoid breaking them. Your repair manual will show you exactly which panels to remove.
* Exterior Access (Less Likely): In some rare cases, the motor might be partially accessible from the outside, but this is less common.
3. Removing the Old Wiper Motor:
* Disconnect Electrical Connectors: Once you've accessed the motor, carefully disconnect the electrical connector(s) from the motor. Take note of how they are connected for easy reassembly. Take pictures if needed.
* Disconnect Linkage: Detach the wiper arm linkage from the motor. This often involves removing a nut or bolt.
* Remove Mounting Bolts: Unscrew the bolts securing the wiper motor to the vehicle body. Again, your repair manual will indicate the number and location of these bolts.
* Remove the Motor: Carefully remove the old wiper motor.
4. Installing the New Wiper Motor:
* Installation is the Reverse of Removal: Follow the steps in reverse order to install the new motor. Ensure the linkage is properly connected and that the motor is securely fastened.
* Reconnect Electrical Connectors: Securely reconnect the electrical connectors.
* Reinstall Trim Panels: Carefully reinstall all removed trim panels and clips.
5. Testing:
* Reconnect Battery: Reconnect the negative battery terminal.
* Test the Wiper: Turn on the rear wiper to ensure it functions correctly.
Important Considerations:
* Rust and Corrosion: In older vehicles, bolts can be seized due to rust and corrosion. Penetrating oil might be necessary to loosen them.
* Damaged Clips: Be very careful when removing and reinstalling trim panels; plastic clips are easily broken. It's a good idea to have replacements on hand.
* Professional Help: If you're uncomfortable with any aspect of this repair, it's always best to seek professional help from a qualified mechanic. Incorrectly installing the motor could lead to further damage.
This is a general guide. Always consult a repair manual specific to your 2007 Ford Explorer for detailed instructions and diagrams. Improper repair can damage your vehicle, so proceed with caution.
