Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, screwdrivers, replacement fuses, and window switch if needed.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect the Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the cover or in the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse: replace it if it’s blown with a new one of the same amperage.

3. Test Window Switches

Remove the door panel to access the window switches:
- Unscrew any visible screws securing the panel.
- Use a trim removal tool to carefully pry the panel away from the door.
Disconnect the switch connector.
Use a multimeter to check for continuity across the switch terminals when activated.
Replace the switch if continuity is not present.

4. Inspect Wiring

With the door panel still removed, visually inspect the wiring harness for any fraying, cuts, or corrosion.
Repair or replace damaged wiring as necessary.
Ensure all connectors are securely fastened.

5. Check Window Motor

Test the window motor directly:
- Connect the battery voltage to the motor terminals to see if it operates.
If the motor does not work, replace it with a new unit.
