Why did one window stop working completely while others are fine?

On my Tiggo 8 Pro, suddenly one of the power windows say rear-left o r front passenger side stopped functioning — pressing the switch does nothing no sound, no movement, while all other windows operate normally. What are the likely causes: a blown fuse, a bad window switch, a damaged door wiring harness, o r a failed motor/regulator for that specific window?

If a single window stops working entirely:

Blown fuse o r faulty switch: Check if the specific window’s fuse is blown o r the switch is malfunctioning.

Damaged wiring harness: Wires in the door can break due to constant opening/closing look for visible damage near the hinge.

Failed motor o r regulator: The window motor o r regulator for that specific door may have burned out.

Action:

Swap the switch with a working one to test.

Inspect the door wiring harness for continuity.

Test the motor by supplying direct 12V power. Replace the faulty motor o r regulator if necessary.
