Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and locate the power window fuse (refer to the owner's manual).
Inspect the fuse; if it is blown, replace it with a fuse of the same amperage (typically 30A).
Reinstall the fuse box cover.

3. Test and Replace Power Window Switch

Disconnect the battery to avoid electrical shorts.
Remove the door panel using a screwdriver and trim tool.
Disconnect the power window switch connector.
Use a multimeter to check for continuity across the switch terminals.
If faulty, replace the switch with an OEM part.
Reconnect the switch and reassemble the door panel.

4. Inspect and Replace Window Motor

If the switch is functional, test the window motor.
Disconnect the battery again.
Remove the door panel to access the window motor.
Disconnect the motor connector and apply direct 12V power to the motor.
If the motor does not operate, replace it with an OEM part.
Reassemble the door panel and reconnect the battery.
