Remove the door panel using a socket set and trim removal tools.
- Sub-steps:
  - Pry off the door handle cover and remove the screws.
  - Carefully detach the door panel clips and lift the panel away.
Disconnect the electrical connector from the power window switch.
Install the new switch by connecting the electrical connector and reassembling the door panel.
Test the operation of the windows.

4. Replace the Power Window Motor

If the switch replacement does not resolve the issue, proceed to replace the motor.
Remove the door panel (as previously described).
Disconnect the power connector from the window motor.
Remove the mounting screws or bolts securing the motor to the door.
Replace the motor with a new component, ensuring it is securely mounted.
Reconnect the wiring and reassemble the door panel.
Test the window operation.
