Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, flathead screwdriver.
Disconnect the negative battery terminal to ensure safety before starting any electrical work.

2. Fuse Inspection

Locate the fuse box under the dashboard or in the engine compartment.
Identify the fuse for the power windows (refer to the owner's manual for the exact location).
Pull the fuse using a fuse puller and inspect it for continuity. Replace it if blown.

3. Switch Testing

Remove the door panel using a flathead screwdriver to access the power window switch.
Disconnect the switch connector and use a multimeter to test for continuity across the switch terminals while pressing the button.
Replace the switch if it is found to be defective.

4. Motor and Wiring Inspection

With the door panel removed, locate the power window motor.
Connect the multimeter to the motor connector and press the window switch. Check for voltage (around 12V).
If there is voltage but no movement, replace the window motor.
If there is no voltage, inspect the wiring harness for breaks or shorts, and repair as necessary.

5. Relay Check

Locate the power window relay in the fuse box.
Remove the relay and test it for continuity with a multimeter.
Replace the relay if found to be faulty.
