Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
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 control panel.
Ensure the switch is in the "unlocked" position before testing the windows.

3. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse; refer to the owner's manual for the exact location and rating.
Remove the fuse using a fuse puller and visually inspect it for a break.
Replace the fuse with a new one of the same rating if it is blown.

4. Test Window Switch

Remove the driver’s side power window switch by gently prying it out with a trim tool.
Use a multimeter to check for continuity across the switch terminals when activated.
If the switch fails the test, replace it with a new switch.

5. Inspect Window Motor and Wiring

If the switch is functional, check the wiring harness that connects to the window motor.
Unplug the motor connector and test for voltage when the switch is pressed.
If there is voltage but the motor does not operate, replace the window motor.
If there is no voltage, trace the wiring back to the switch for continuity.

6. Reassemble and Test

Reconnect all components and ensure all connections are secure.
Reconnect the battery and test the power windows to confirm operation.
