Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check Window Lock Switch

Locate the window lock switch on the driver’s side door panel.
Ensure the switch is in the 'unlocked' position to allow operation of all windows.

3. Replace Blown Fuses

Locate the fuse box (typically under the dashboard or in the engine bay).
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 for any signs of damage; if blown, replace it with a new fuse of the same amperage (usually 30A for power windows).

4. Test Power Window Switches

Remove the door panel using a trim removal tool or screwdriver.
Disconnect the power window switch connector.
Use a multimeter to test continuity across the switch terminals while pressing the switch.
Replace the switch if no continuity is detected.

5. Inspect Wiring Harness

While the door panel is removed, visually inspect the wiring harness for any frayed wires or disconnections.
Repair or replace any damaged wiring as necessary.

6. Reassemble and Test

Reconnect the door panel and secure it with screws or clips.
Reconnect the vehicle battery.
Test all power windows to verify proper functionality.
