Before You Begin:
* Safety First: Disconnect the negative battery terminal to prevent electrical shocks.
* Gather Tools: You'll likely need a socket set (various sizes), screwdrivers (Phillips and possibly flathead), possibly a wrench, and possibly a trim removal tool to avoid scratching the plastic.
* Repair Manual: A factory service manual or a reputable online repair guide specific to your Caravan's year and model is invaluable. This will provide detailed diagrams and torque specifications.
General Steps (May Vary):
1. Access the Wiper Motor: This usually involves removing the interior trim panel on the rear hatch or tailgate. This often entails:
* Removing the rear wiper arm and blade (may require a special tool to release the arm).
* Removing interior plastic panels. This typically involves carefully prying off plastic clips and fasteners. Be gentle to avoid breaking them.
* Possibly removing the rear hatch or tailgate liner for better access.
2. Disconnect Electrical Connections: Once you have access to the motor, carefully disconnect the electrical connector(s) from the motor. Take photos or make notes to remember how they were connected.
3. Disconnect Linkage: The wiper motor is connected to the wiper arm mechanism by a linkage. Disconnect this linkage. This may involve removing bolts or clips.
4. Remove the Wiper Motor: The motor is typically secured by bolts or nuts. Carefully remove these fasteners to release the motor.
5. Install the New Wiper Motor: Reverse the removal process to install the new motor. Ensure the linkage is correctly reconnected and the electrical connectors are securely attached.
6. Reconnect and Test: Reconnect the electrical connectors and the battery. Test the rear wiper to ensure it's functioning correctly.
7. Reassemble: Put everything back together, securing all panels and trim pieces.
Important Considerations:
* Year and Model: The location and access to the motor can vary significantly between Caravan years and models. Your repair manual is essential.
* Plastic Clips: Be very careful when removing and reinstalling plastic clips. They are easily broken.
* Electrical Connections: Make sure the electrical connections are secure to avoid short circuits.
* Torque Specifications: Use the correct torque specifications from your repair manual when tightening bolts and nuts to prevent damage.
