Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Screwdriver set
- Wiring diagram for reference
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram on the cover or in the owner’s manual.
Visually inspect the fuse for continuity; replace it if blown with an identical amperage fuse.

3. Test and Replace Window Switches

Remove the door panel using a screwdriver to access the window switch connector.
Disconnect the window switch and test it with a multimeter for continuity when the button is pressed.
If faulty, replace the switch with a new component.

4. Inspect Wiring and Connectors

Check the wiring harness leading to the door for any signs of fraying or damage.
Ensure that all connectors are fully seated and free from corrosion.
Repair or replace any damaged wires or connectors as necessary.

5. Test Window Motors

With the door panel still removed, access the window motor.
Apply direct battery voltage to the motor terminals using jumper wires to determine if the motor is operational.
If the motor does not respond, replace it with a new motor.

6. Reassemble and Test

Reattach the door panel securely after all repairs and replacements are made.
Reconnect the battery and test the power windows to ensure full functionality.
