1. Preparation:
* Safety First: Disconnect the negative battery terminal to prevent electrical shocks.
* Gather Tools: You'll need a variety of tools, likely including: screwdrivers (Phillips and flathead), possibly Torx bits, sockets and wrenches (various sizes), possibly panel removal tools, a wiring harness diagram (very helpful!), and a new rear window motor (ensure you get the correct one for your year and model).
* Consult a Repair Manual: A Haynes or Chilton repair manual specific to your year and model Plymouth Voyager is essential. These manuals provide detailed diagrams, torque specifications, and step-by-step instructions crucial for avoiding damage. Online resources may offer some guidance, but a dedicated manual is far superior.
2. Accessing the Motor:
* Interior Panel Removal: This is often the most challenging part. You'll need to carefully remove interior trim panels around the rear window. This usually involves prying gently with plastic panel removal tools to avoid scratching or breaking the panels. Be methodical and take pictures as you go to help with reassembly.
* Wiring Harness Disconnection: Once the panels are removed, you'll locate the motor. Disconnect the wiring harness connected to the motor. Take note of how it's connected for reassembly.
3. Motor Removal and Replacement:
* Motor Mounting: The motor is typically mounted either directly to the window mechanism or to a bracket. The method of removal depends entirely on your specific Voyager's design. This is where your repair manual will be crucial. You may need to remove bolts, screws, or clips.
* Removing the Old Motor: Carefully remove the old motor, paying attention to how the linkage connects to the window mechanism.
* Installing the New Motor: Install the new motor, ensuring proper alignment with the window mechanism and linkage.
* Reconnecting the Wiring Harness: Securely reconnect the wiring harness.
4. Reassembly:
* Reinstalling Panels: Carefully reinstall the interior trim panels, ensuring they're properly secured.
* Testing: Reconnect the negative battery terminal. Test the rear window operation to ensure the new motor works correctly.
Important Considerations:
* Year-Specific Differences: The exact procedure varies considerably between Voyager model years. A repair manual for your specific year is critical.
* Window Regulator Issues: Sometimes the problem isn't the motor itself, but a faulty window regulator. Inspect the regulator for wear or damage before replacing the motor.
* Professional Help: If you're not comfortable with automotive repairs, it's best to take your Voyager to a qualified mechanic. Improperly attempting this repair could lead to further damage.
This is a general overview. Without knowing your Voyager's year, I cannot provide more specific instructions. Always consult a repair manual specific to your vehicle. Trying to perform this repair without one is strongly discouraged.
