2. Faulty switch: The switch that controls the electric windows may be faulty. Try operating the windows from the other switches in the car to see if they work. If the windows work from the other switches, then the switch on the driver's door is most likely faulty.
3. Faulty wiring: The wiring that connects the switch to the window motors may be faulty. Check the wiring for any loose connections or breaks. If you find any loose connections, reconnect them. If there are any breaks in the wiring, you will need to replace the wiring.
4. Faulty window motor: The window motor itself may be faulty. If the window motor is faulty, you will need to replace it with a new one.

1. Remove the door panel.

5. Install the new window motor in the door.
