Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and replacement fuses.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse related to the power windows using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if the filament is broken, replace it with a new fuse of the same amperage.

3. Test and Replace the Power Window Switch

Remove the door panel using a socket set and screwdrivers to access the power window switch.
Disconnect the wiring harness from the switch and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new switch by reconnecting the wiring harness and securing the door panel back in place.

4. Check and Replace the Power Window Motor

If the switch is functional, access the power window motor by removing the door panel.
Disconnect the motor's wiring harness and use a multimeter to check for power at the connector when the switch is activated.
If no power is present, inspect the wiring; if power is present but the motor does not operate, replace the motor.

5. Reassemble and Test

Reattach the door panel securely and reconnect the negative battery terminal.
Test the windows by operating each switch to ensure proper function.
