Solution

1. Preparation

Gather tools: socket set, multimeter, screwdrivers, and a replacement fuse if needed.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box, usually found inside the glove compartment or under the dashboard.
Identify the power window fuse using the diagram.
Remove the fuse and inspect it; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the power windows.

3. Inspect and Replace Power Window Switch

Remove the door panel using the appropriate tools, carefully prying it away from the clips.
Disconnect the power window switch connector.
Test the switch with a multimeter for continuity. If faulty, replace with a new switch.
Reassemble the door panel after replacement.

4. Test and Replace Window Motor

If the switch is functioning, remove the interior door panel to access the window motor.
Disconnect the motor's electrical connector and test it with a multimeter for power.
If no power is detected, check wiring continuity. If power is present but the motor does not operate, replace the motor.
Reinstall the door panel, ensuring all connections are secure.

5. Final Assembly

After verifying all components, reattach the door panel, ensuring all clips are snapped into place.
Reconnect the battery and perform a final test of the power windows.
