Solution

1. Preparation

Gather necessary tools and parts.
Safety warning: Ensure the vehicle is turned off and keys are removed to prevent accidental activation.

2. Check and Replace Fuses

Locate the fuse box (usually found under the dashboard or in the engine bay).
Remove the fuse related to the power windows (refer to the owner's manual for the specific fuse location).
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Inspect and Test Window Switches

Remove the door panel using a trim tool or screwdriver.
Disconnect the wiring harness from the window switch.
Use a multimeter to test for continuity across the switch terminals while pressing the switch.
If the switch is faulty, replace it with a new switch.

4. Check Window Motor Functionality

If the switch is functioning, reconnect the wiring and test the window motor by applying battery power directly to the motor terminals.
If the motor does not operate, it may need to be replaced.
To replace, remove the motor from the window regulator by unscrewing the mounting screws.

5. Reassemble Components

Reinstall the window motor or switch as necessary.
Reattach the door panel securely, ensuring all clips and screws are in place.
