Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock and damage.
Ensure you have a clean, well-lit workspace.

2. Inspect and Confirm Window Lock Switch

Locate the window lock switch on the driver's side door.
Toggle the switch to the "unlock" position.
Reconnect the battery and test the power windows again.

3. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Reference the fuse box diagram to locate the power window fuses.
Remove the fuses using a fuse puller; inspect them visually for any damage.
Replace any blown fuses with new ones of the same amperage rating.

4. Test Window Switches

Remove the switch panel from the driver's side door using a trim tool.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity across the switch terminals when pressed.
If the switch is faulty, replace it with a new one.

5. Inspect Wiring and Connections

Visually inspect the wiring harness for any signs of wear, fraying, or disconnections.
Check the connectors for corrosion or loose connections.
Repair or replace any damaged wiring or connectors as necessary.

6. Test Power Window Motors

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Use jumper wires to connect the motor directly to the battery to test its functionality.
If the motor does not operate, replace it with a new one.
