Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box, typically found 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).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a fuse of the same amperage rating.

3. Inspect Window Switch

Remove the door panel to access the window switch assembly.
Disconnect the switch harness from the window switch.
Use a multimeter to check for continuity across the switch terminals while pressing the switch.
If no continuity is detected, replace the window switch.

4. Test Window Motors

With the door panel still removed, access the window motor.
Disconnect the motor harness.
Using jumper wires, connect the motor directly to the battery (positive to positive, negative to negative).
If the motor operates, it is functional; if not, replace the window motor.

5. Reassemble and Test

Reconnect all switches and motors, ensuring all connections are secure.
Reinstall the door panel and ensure all clips are fastened properly.
Reconnect the vehicle battery.
Test the window operation from both the driver's control and individual window switches.
