Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, trim removal tools, socket set.
Ensure the vehicle is parked on a flat surface with the ignition turned off.

2. Check and Replace Fuse

Locate the fuse box: Refer to the owner's manual for the specific fuse location for the power windows.
Inspect the fuse: Remove the fuse and visually check for signs of a blown fuse (broken filament).
Replace if necessary: If the fuse is blown, replace it with one of the same amperage rating.

3. Inspect Window Switches

Remove door panel: Use trim removal tools to carefully detach the door panel, exposing the switch assembly.
Test switches: Use a multimeter to check for continuity across the switch terminals when pressed.
Replace faulty switches: If the switch is defective, replace it with a new one.

4. Check Window Motors

Access window motor: Remove the door panel to access the window motor.
Test motor operation: Connect the motor directly to a power source to see if it functions. If not, it may need replacement.
Reinstall components: If the motor is functioning, ensure all connections are secure before reassembling the door panel.

5. Software Reset

Perform a reset: On the touchscreen, go to 'Controls' > 'Service' > 'Power Off' and wait for the system to turn off completely.
Restart the system: After a few minutes, press the brake pedal to turn the vehicle back on and check window functionality.
