Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, door panel removal tool, and a flathead screwdriver.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box as indicated in the owner's manual.
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage (burnt or broken).
Replace with a new fuse of the same amperage if damaged.

3. Inspect Window Switch

Remove the door panel using a door panel removal tool.
Disconnect the window switch connector.
Use a multimeter to check for continuity across the switch terminals when pressed.
If the switch is found faulty, replace it with a new one.

4. Test Window Motors

Disconnect the window motor connector.
Using jumper wires, connect the motor directly to the vehicle battery to test its function.
If the motor operates, the issue may lie in the wiring; if it doesn't, replace the motor.

5. Check Wiring Harness

Inspect the wiring harness for visible damage, such as fraying or broken wires.
Repair any damaged wires with soldering and heat shrink tubing or replace the harness if severely damaged.

6. Reassemble Components

Reconnect all components and wiring while ensuring no wires are pinched.
Reattach the door panel securely.
Reconnect the vehicle battery.
