Here's a general procedure:
1. Preparation:
* Gather tools: You'll need a screwdriver set (likely Phillips and flathead), possibly a socket set (depending on the door panel fasteners), panel removal tools (plastic pry tools are recommended to avoid scratching), and possibly some wire strippers/crimpers if you need to repair wiring. A flashlight will be helpful.
* Consult a repair manual: A Haynes or Chilton manual specific to your 2002 Chevy Cavalier will provide detailed diagrams and instructions. This is highly recommended, as it will show you exactly where everything is located and how it's assembled.
* Obtain the replacement motor: Make sure you get the correct motor for the specific door you're repairing.
2. Door Panel Removal:
* Locate and remove the door panel: This usually involves removing screws found in the armrest, door handle area, and possibly under the door pull. Use plastic pry tools to carefully separate the panel from the door, working your way around the perimeter. Be gentle to avoid breaking any clips. There might be some electrical connectors attached; disconnect them carefully. The repair manual will be indispensable here.
3. Accessing the Window Motor:
* Remove any remaining obstructions: Once the panel is off, you might need to remove other components like the window regulator, speaker, or other trim pieces to access the window motor. Again, your repair manual will guide you here. Take pictures as you go to help with reassembly.
* Disconnect the electrical connector: Unplug the electrical connector from the window motor.
4. Removing the Old Motor:
* Remove the window motor mounting bolts: These are typically located on the motor itself. Carefully remove the bolts and detach the motor from the regulator. Note the position of everything for reassembly.
5. Installing the New Motor:
* Attach the new motor: Carefully attach the new motor to the window regulator using the bolts you removed earlier.
* Reconnect the electrical connector: Securely plug the electrical connector back onto the new motor.
6. Reassembly:
* Reinstall all removed components: Carefully put everything back in its place, reversing the steps from the removal process. Make sure the window regulator is properly aligned.
* Reconnect electrical connectors: Ensure that all the electrical connectors are properly secured.
* Reattach the door panel: Snap the door panel back onto the door, making sure all the clips are properly engaged and the screws are tightened.
7. Testing:
* Reconnect the negative battery terminal: Reconnect the battery terminal.
* Test the window: Operate the power window switch to verify that the new motor is functioning correctly.
Important Considerations:
* Wiring: If the wiring to the motor is damaged, you might need to repair or replace it. This requires electrical knowledge and appropriate tools.
* Window Regulator: Sometimes, the window regulator itself is the problem, not the motor. If the window is binding or moving erratically even with a new motor, the regulator may need to be replaced as well.
* Safety: Be careful when working with electrical components. Always disconnect the battery terminal before starting any work.
This is a general outline. The exact procedure and difficulty will vary depending on your specific vehicle and your experience. Using a repair manual specifically for your 2002 Chevy Cavalier is crucial for success. If you are uncomfortable performing this repair yourself, consider taking your vehicle to a qualified mechanic.
