Solution

1. Preparation

Tools Required: Socket set, flathead screwdriver, Phillips screwdriver, multimeter, panel removal tool, OBD-II scanner.
Safety Warning: Disconnect the vehicle battery before beginning any electrical work to prevent short circuits or shocks.

2. Check and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and locate the specific fuse for the power windows (refer to the owner's manual for the exact location).
Inspect the fuse for continuity using a multimeter. Replace it if it is blown with a new fuse of the same amperage.

3. Inspect and Test Switches

Remove the door panel using a panel removal tool to access the window switch assembly.
Disconnect the switch connectors and test for continuity with a multimeter when the switch is pressed.
If faulty, replace the switch with a new one.

4. Inspect Window Motors and Regulator

While the door panel is removed, visually inspect the window motor and regulator for any signs of damage or wear.
Check the wiring harness for loose connections or frayed wires.
If the motor is suspected to be faulty, unscrew it from the door and replace it with a new motor.

5. Reassemble and Restore Power

Once repairs are completed, reattach the door panel securely.
Reconnect the vehicle battery.
Test the power window operation to ensure functionality.
