Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and wire connectors.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover or the owner's manual.
Remove the fuse using fuse pullers or pliers.
Check the fuse for continuity using a multimeter; replace it if blown with a fuse of the same amperage.

3. Inspect and Test Switches

Remove the door panel using a screwdriver to access the power window switch.
Disconnect the switch connector and test for continuity with a multimeter.
If defective, replace the power window switch with a new one.

4. Test Power Window Motor

If the switch is functional, reconnect the switch and check for voltage at the power window motor while activating the switch.
If no voltage is detected, trace the wiring back to the switch for any breaks.
If voltage is present but the window does not move, replace the power window motor.

5. Check Window Regulator

With the door panel removed, inspect the window regulator for any physical obstructions or mechanical failures.
If the regulator is damaged, remove it by unscrewing it from the door and replace it with a new unit.
