Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid electrical shock.

2. Check Window Lock Switch

Locate the window lock switch on the driver’s side control panel.
Ensure it is in the "off" position to allow operation of all windows.

3. Inspect Fuses

Open the fuse box, which is usually located under the dashboard or in the engine compartment.
Identify the fuse related to the power windows (refer to the owner's manual).
Remove the fuse using a fuse puller and visually inspect it for damage. Replace if blown.

4. Test Power Window Switches

Remove the door panel using a socket set and trim removal tools.
Disconnect the electrical connector from the window switch.
Using a multimeter, check for continuity across the switch terminals when pressed. Replace the switch if faulty.

5. Check Wiring and Connectors

Inspect wiring harnesses leading to the power window motor for fraying or breaks.
Ensure all connectors are secure and free from corrosion. Clean or replace as necessary.

6. Test Power Window Motor

With the door panel still removed, locate the power window motor.
Disconnect the motor from the wiring harness.
Use jumper wires to connect the motor directly to the battery. If it operates, the motor is functional; otherwise, replace the motor.
