Steps (General Outline):
1. Disconnect the Battery: This is crucial for safety to prevent short circuits.
2. Remove the Interior Door Panel: This involves carefully prying off the panel using panel removal tools. Start by removing screws around the armrest, door handle, and any other visible fasteners. There are often plastic clips holding the panel in place. Be gentle to avoid breaking the clips. A repair manual will show you the exact locations of the fasteners.
3. Access the Window Regulator and Motor: Once the door panel is off, you'll see the window regulator mechanism and the motor. You might need to remove some additional parts to gain access, like screws or plastic covers. The motor is typically attached to the regulator.
4. Disconnect the Electrical Connector: Carefully disconnect the electrical connector from the window motor. Take a picture or note the position of the wires before disconnecting.
5. Remove the Old Motor: This usually involves removing bolts or screws attaching the motor to the regulator. Again, consult your repair manual for the precise location and type of fasteners.
6. Install the New Motor: Attach the new motor in the same way the old one was attached. Make sure it's securely fastened.
7. Reconnect the Electrical Connector: Carefully reconnect the electrical connector to the new motor, ensuring the wires are correctly seated.
8. Reconnect the Window Regulator (if necessary): If you had to disconnect anything from the regulator, carefully reconnect it. Make sure the window moves freely up and down manually.
9. Lubricate the Window Regulator: Apply a small amount of grease to the moving parts of the window regulator to ensure smooth operation.
10. Reinstall the Interior Door Panel: Carefully reinstall the door panel, ensuring all clips and screws are securely fastened.
11. Test the Window: Reconnect the battery and test the power window to ensure it operates correctly in both directions.
12. Inspect your work: Check for any loose parts or wires and make sure the door panel is properly sealed to prevent water intrusion.
