Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Ensure the vehicle is parked in a safe location.

2. Check Window Lock Button

Locate the window lock button on the driver’s control panel.
Ensure that the window lock is not activated; toggle the switch to the off position if it is.

3. Inspect Fuses

Locate the fuse box, typically found in the front trunk area.
Remove the cover to access the fuses.
Identify the fuses related to the windows (consult the owner's manual for specific fuse locations).
Use a fuse puller to remove each window fuse and inspect for damage.
Replace any blown fuses with identical-rated fuses.

4. Examine Wiring and Connectors

Remove the door panel using a trim tool to avoid damage.
Inspect all wiring and connectors leading to the window motor.
Look for any signs of wear, fraying, or disconnection.
Reconnect or repair any damaged wires as necessary.

5. Test Window Switches

Remove the window switch assembly from the door panel.
Use a multimeter to check for continuity across the switch terminals.
Replace the switch assembly if it fails the continuity test.

6. Reassemble and Test

Reinstall the door panel and ensure all clips are securely fastened.
Reconnect the vehicle battery.
