Solution

1. Preparation

Tools Required:
- Multimeter
- OBD-II scanner
- Socket set
- Screwdrivers (flat and Phillips)
- Wire connectors (if needed)
Disconnect the vehicle battery before starting any electrical work.

2. Inspect the Window Lock Switch

Locate the window lock switch on the driver's side door.
Ensure the switch is in the "off" position.
Test the switch for proper function; replace if faulty.

3. Check the Fuse

Open the fuse box, typically located under the dashboard or in the engine compartment.
Identify the fuse for the power windows using the diagram provided in the owner’s manual.
Remove the fuse and inspect it for continuity; replace if blown with the same amperage fuse.

4. Test the Power Window Switches

Remove the door panel using a screwdriver to access the power window switch.
Disconnect the switch connector and use a multimeter to check for continuity across the terminals when the switch is pressed.
Replace the switch if it fails the continuity test.

5. Inspect Wiring and Connections

Visually inspect the wiring harness for any signs of wear, fraying, or disconnection.
Ensure all connectors are securely attached and free of corrosion.
Repair or replace any damaged wires or connectors as necessary.

6. Test the Power Window Motor

Remove the door panel to access the window motor.
Disconnect the motor connector and apply direct battery voltage to the motor terminals.
If the motor operates, it may be functioning correctly; if not, replace the motor.
