Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and a test light.
Ensure the vehicle is turned off and the key is removed from the ignition.

2. Check Window Lock Switch

Locate the window lock switch on the driver's door.
Ensure it is not engaged; if it is, disengage it and test the windows again.

3. Inspect and Replace the Fuse

Locate the fuse box and identify the fuse for the power windows using the fuse panel diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown with a fuse of the same amperage.

4. Test the Window Switches

Remove the door panel to access the window switch assembly.
Disconnect the wiring harness from the window switches.
Use a multimeter to check for continuity on each switch when pressed. Replace any faulty switches.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness for any frayed wires or corrosion at the connector points.
Repair any damaged wires or replace corroded connectors.

6. Test Window Motors

Disconnect the window motor from the wiring harness.
Use a test light or multimeter to verify the motor receives power when the window switch is activated.
If no power is detected, check the harness leading to the motor. If power is confirmed, replace the window motor.
