Remove the Old Motor: Locate the power window motor and disconnect it from the electrical connections. Remove the screws holding the motor in place, and gently pull the motor out of the door.
Install the New Motor: Take the new motor and place it in the same position as the old one. Secure it in place using the screws that were removed earlier.
Connect the Electrical Connections: Connect the electrical connections to the new motor, making sure to tighten all screws and nuts securely.
