Solution

1. Preparation

Gather tools: multimeter, socket set, screwdrivers, and a test light.
Ensure the vehicle is parked with the ignition in the OFF position.
Disconnect the battery to prevent electrical shock.

2. Check and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller.
Inspect the fuse for any signs of damage (broken filament).
Replace with a new fuse of the same amperage if necessary.

3. Inspect and Replace the Power Window Switch

Remove the door panel using a screwdriver and pry tool to access the switch.
Disconnect the power window switch connector.
Test the switch using a multimeter for continuity.
Replace the switch if it fails the continuity test.

4. Check the Window Motor

Access the window motor by removing the door panel completely.
Disconnect the window motor connector.
Test for voltage at the connector while operating the switch.
Replace the window motor if there is no voltage present or if it fails to operate when voltage is applied directly.

5. Reassemble and Test

Reinstall the door panel securely.
Reconnect the battery.
Test the functionality of the power windows from both the driver's side and individual door switches.
