Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked securely and the ignition is off.

2. Check Window Lock Switch

Locate the window lock switch on the driver's side door.
Ensure that the switch is in the "off" position to allow operation of all windows.

3. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Open the driver's side fuse panel (located under the dashboard).
Locate the fuse for the power windows (refer to the owner's manual for the exact location).
Remove the fuse and inspect it. If blown, replace it with a fuse of the same amperage (typically 30A).

4. Test Power Window Switches

Tools Required: Multimeter
Disconnect the power window switch from the wiring harness.
Set the multimeter to continuity mode.
Test the switch terminals by pressing the switch; continuity should be present when the switch is pressed. Replace the switch if no continuity is detected.

5. Inspect Wiring Harness

Remove the door panel using a socket set and trim removal tools.
Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
If damage is found, repair or replace the wiring as necessary.

6. Check Window Motor

Tools Required: Socket set, screwdriver
Locate the window motor within the door panel.
Disconnect the motor's wiring harness and test for voltage using a multimeter while pressing the window switch.
If voltage is present but the motor does not operate, the motor will likely need replacement.
